XENPAK-10GB-SR Overview
XENPAK-10GB-SR uses the XENPAK form factor for hot-swappable placement in Ethernet XENPAK ports on Cisco switch and router legacy hosts. Line operation provides 10 Gbps Ethernet signaling through 10GBASE-SR interfaces and legacy Cisco optical module bays across chassis uplink slots. Optical media is multimode fiber with 50-micron laser-optimized cabling and legacy 62.5-micron installed plant compatibility for short-reach Ethernet spans. Dual SC/PC connectors provide separate transmit and receive paths through PC or UPC patch cord assemblies in the optical interface. Wavelength operation uses 850 nm optics across the 840 nm to 860 nm transmit-and-receive window for shortwave signaling links. Maximum reach is 400 m on OM4, 300 m on OM3, 82 m on OM2, and 33 m on OM1. XENPAK-10GB-SR carries the Commercial operating temperature class for standard Cisco XENPAK optical-module environmental operation.
A VCSEL transmitter launches shortwave optical output for IEEE 802.3ae 10GBASE-SR operation across Cisco XENPAK host ports and line cards. PIN receiver circuitry converts incoming multimode optical input into electrical signaling for the XENPAK host interface and receive-path electronics. TX power delivers -7.3 dBm to -1.2 dBm average launch power across Cisco optical operating conditions and end-of-life limits. RX sensitivity reaches -9.9 dBm at the receive minimum input level for the short-reach optical budget using IEEE test patterns. Receiver overload tolerates -1.0 dBm at the maximum receive input level before optical front-end saturation under maximum input conditions. With 64b/66b encoding, 10GBASE-R framing carries Ethernet payloads across the serial shortwave optical lane without WAN PHY framing. IEEE 802.3ae and XENPAK MSA INF-8474i establish Ethernet operation and XENPAK module interface requirements for compliant switch ports. Power consumption stays at 8 W maximum for XENPAK-10GB-SR during Cisco 10GBASE-SR optical operation across installed Cisco hosts.
Cisco Catalyst 6500 Series and Cisco 7600 Series hosts provide documented XENPAK 10GBASE-SR deployment targets and legacy chassis families. Deployment environments span campus core, data center aggregation, service provider edge, and enterprise wiring-closet uplink refreshes. Required cable grade is OM4 for 400 m installations and OM3 for 300 m runs. OM2 and OM1 cabling serve shorter legacy multimode links within the documented Cisco reach table. Interoperable 10GBASE-SR XENPAK, X2, XFP, and SFP+ endpoints fit same-link optical migration projects with matched optics.

XENPAK-10GB-SR Use Case
Legacy Chassis 10G Access
The Cisco XENPAK-10GB-SR operates in a legacy 10 GbE switch or router slot where short-reach multimode fiber connects chassis equipment inside the same room or nearby row. Its XENPAK form factor matches platforms built before SFP+ became the standard 10G optic, while the 850 nm 10GBASE-SR interface runs across OM3 multimode fiber up to 300 meters. In this position, XENPAK-10GB-SR preserves 10G access on existing modular hardware and gives the topology a defined short-reach optical handoff for rack aggregation edge.
Aggregation Switch Interconnect
The XENPAK-10GB-SR sits between aggregation switches that still use XENPAK 10G ports and multimode fiber patching. The dual SC interface terminates the optic directly into the installed connector format, and the 850 nm SR link keeps the span aligned with short-distance OM3 cabling. This role fits switch-to-switch interconnects where replacing the chassis is outside the current refresh window. The aggregation layer gains a 10 GbE optical path that keeps legacy port hardware active without changing the multimode cabling plant design.
Data Center Row Handoff
The XENPAK-10GB-SR operates as a data center row interconnect for older Cisco platforms that expose 10G XENPAK bays instead of SFP+ cages. It uses multimode fiber and 10GBASE-SR optics for short spans, with OM3 reach up to 300 meters and 850 nm transmission across the row or room. The module places a 10 GbE link between access and aggregation equipment without introducing single-mode optics into a short MMF run. The network keeps a defined upgrade bridge for legacy 10G switching.

Questions & Answers
What is XENPAK-10GB-SR?
XENPAK-10GB-SR is a Cisco 10GBASE-SR XENPAK optical transceiver for short-reach 10 Gigabit Ethernet over multimode fiber. It uses an 850 nm optical interface, dual SC connectors, and the larger XENPAK form factor used by older Cisco switching and routing platforms. It supports up to 300 m on OM3 multimode fiber.
What does the Cisco XENPAK-10GB-SR model number mean?
The XENPAK-10GB-SR model number identifies a Cisco XENPAK form factor transceiver for 10 Gigabit Ethernet short-reach optical links. XENPAK describes the physical module type, 10GB identifies 10 Gigabit Ethernet operation, and SR means short reach. The module is designed for multimode fiber cabling rather than single-mode long-reach fiber.
Is XENPAK-10GB-SR an optical transceiver or a cable?
XENPAK-10GB-SR is an optical transceiver module, not a fixed cable. It plugs into a compatible XENPAK port on older Cisco hardware and connects to a separate multimode fiber patch cable. The module uses dual SC connectors, so it needs SC duplex multimode fiber cabling rather than the LC patch leads used by many SFP+ optics.
Where does XENPAK-10GB-SR sit in the Cisco optics lineup?
XENPAK-10GB-SR sits in Cisco's older 10GBASE XENPAK module family as the short-reach multimode option. It was used before smaller X2, XFP, SFP+, and SFP28 modules became common. Related Cisco XENPAK alternatives include XENPAK-10GB-LR+, XENPAK-10GB-ER+, XENPAK-10GB-ZR, XENPAK-10GB-LRM, XENPAK-10GB-LX4, and XENPAK-10GB-CX4.
What form factor does XENPAK-10GB-SR use?
XENPAK-10GB-SR uses the XENPAK form factor, which is larger than X2, XFP, and SFP+ transceivers. The module is intended for hardware with native XENPAK slots and is not physically interchangeable with SFP+ ports. Buyers replacing failed optics should verify the line card or supervisor has XENPAK cages before ordering this SKU.
What data rate does XENPAK-10GB-SR support?
XENPAK-10GB-SR supports 10 Gigabit Ethernet operation through a 10GBASE-SR optical interface. It is used for 10G Ethernet links between compatible Cisco platforms over multimode fiber. It is not a 1G optic, not a 25G optic, and not a copper DAC cable, so both connected ports must support 10GBASE-SR optical Ethernet.
What wavelength does XENPAK-10GB-SR use?
XENPAK-10GB-SR uses an 850 nm short-reach multimode optical interface. The 850 nm wavelength is standard for 10GBASE-SR links over laser-optimized multimode fiber. It should be connected to another compatible 10GBASE-SR optical interface on the far end, using multimode fiber rather than single-mode fiber designed for 1310 nm or 1550 nm optics.
What reach does XENPAK-10GB-SR support?
XENPAK-10GB-SR supports 26 m on standard FDDI-grade multimode fiber and up to 300 m on 2000 MHz-km OM3 multimode fiber. Cisco documentation also lists up to 400 m on 4700 MHz-km OM4 multimode fiber. Actual link design should check fiber grade, patching quality, connector cleanliness, and receiver power at both ends.
What connector type does XENPAK-10GB-SR use?
XENPAK-10GB-SR uses dual SC connectors for transmit and receive fiber strands. This is different from many newer Cisco 10G SFP+ optics, which usually use duplex LC connectors. Buyers should confirm the patch panel and transceiver at the far end use the correct connector format, or plan approved SC-to-LC multimode patching where needed.
Does XENPAK-10GB-SR support DOM?
XENPAK-10GB-SR should not be assumed to provide DOM unless the exact module revision and host platform report diagnostics. Cisco's end-of-sale listing describes XENPAK-10GB-SR as a 10GBASE-SR XENPAK module, while DOM is explicitly stated for some other XENPAK part descriptions such as LR+ and ER+. Buyers should verify diagnostics on the target platform.
What is XENPAK-10GB-SR used for?
XENPAK-10GB-SR is used for short 10G Ethernet links on legacy Cisco platforms with XENPAK ports. Common uses include data center interconnects inside a room, campus distribution links, aggregation connections, and replacement optics for older Catalyst or routing hardware. It is most practical where installed equipment still depends on XENPAK rather than SFP+ interfaces.
What environment size fits XENPAK-10GB-SR?
XENPAK-10GB-SR fits legacy enterprise, service provider, campus, and data center environments that still operate Cisco platforms with XENPAK slots. Its 300 m OM3 reach suits in-building fiber runs, equipment rooms, nearby aggregation blocks, and short campus risers. For modern refresh projects, buyers often evaluate SFP+ switches instead of expanding XENPAK infrastructure.
What workloads suit XENPAK-10GB-SR?
XENPAK-10GB-SR suits 10G Ethernet traffic between older Cisco switching or routing platforms, including aggregation, backup, virtualization, storage Ethernet, and campus backbone traffic. It is not suitable for long single-mode links, 25G upgrades, or hardware without XENPAK slots. The module mainly serves maintenance, spares, and lifecycle extension for installed 10G infrastructure.
Can XENPAK-10GB-SR work in campus aggregation links?
XENPAK-10GB-SR can work in campus aggregation links when the distance fits multimode fiber reach limits and both ends support 10GBASE-SR. It is useful between nearby distribution, core, or data center switches in the same building. For links beyond OM3 or OM4 reach, buyers should compare long-reach XENPAK optics or newer platform options.
Which Cisco platforms are compatible with XENPAK-10GB-SR?
XENPAK-10GB-SR is associated with older Cisco platforms that supported XENPAK interfaces, including Catalyst 6500, Cisco 7600, Catalyst 3750 Series variants, and Cisco CRS-1 environments depending on the exact module and line card. Compatibility must be checked against the specific chassis, supervisor, line card, operating system, and software release before ordering replacement optics.
Does XENPAK-10GB-SR work with Catalyst 6500 switches?
XENPAK-10GB-SR can work with compatible Cisco Catalyst 6500 10 Gigabit Ethernet modules that provide XENPAK ports, such as older 10GE line cards and supervisor uplink designs. Buyers should verify the exact Catalyst 6500 line card, software train, and optical support matrix. Some later Catalyst 6500 modules use X2 or SFP+ rather than XENPAK.
Does XENPAK-10GB-SR interoperate with X2, XFP, or SFP+ 10GBASE-SR optics?
XENPAK-10GB-SR can interoperate optically with matching 10GBASE-SR interfaces in other form factors when both ends use compatible multimode fiber, wavelength, reach, and Ethernet speed. Physical form factors do not need to match across a fiber link. The local port must still accept XENPAK, while the far end may use X2, XFP, or SFP+ SR optics.
What fiber standard should be used with XENPAK-10GB-SR?
XENPAK-10GB-SR should use multimode fiber, preferably OM3 for up to 300 m or OM4 for up to 400 m where supported. Legacy FDDI-grade multimode fiber supports only 26 m, so older cabling can sharply limit reach. Duplex SC patching, clean connectors, and tested fiber plant loss are important for stable 10G operation.
How does XENPAK-10GB-SR compare with XENPAK-10GB-LR+?
XENPAK-10GB-SR is a short-reach 850 nm multimode optic for links up to 300 m on OM3. XENPAK-10GB-LR+ is a long-reach single-mode optic for links up to 10 km. XENPAK-10GB-SR fits in-building multimode runs, while XENPAK-10GB-LR+ fits longer campus, service provider, or interbuilding single-mode links.
How does XENPAK-10GB-SR compare with XENPAK-10GB-ER+?
XENPAK-10GB-SR uses multimode fiber for short 10GBASE-SR links, while XENPAK-10GB-ER+ uses single-mode fiber for extended-reach 10G links up to 40 km. XENPAK-10GB-SR is the right choice for nearby switches on OM3 cabling. XENPAK-10GB-ER+ is chosen for long-distance fiber paths where optical budget and dispersion requirements are higher.
How does XENPAK-10GB-SR compare with XENPAK-10GB-LX4?
XENPAK-10GB-SR is a standard 850 nm short-reach multimode module for 10GBASE-SR links. XENPAK-10GB-LX4 uses a different optical approach and was often used where legacy multimode fiber reach or cabling conditions made SR less suitable. Buyers should choose XENPAK-10GB-SR for clean OM3 short links and LX4 only when the installed fiber design requires it.
How does XENPAK-10GB-SR compare with XENPAK-10GB-CX4?
XENPAK-10GB-SR is an optical module for multimode fiber links up to 300 m on OM3. XENPAK-10GB-CX4 is a copper CX4 option for very short 10G connections over CX4 cabling, typically inside a rack or nearby cabinet. XENPAK-10GB-SR is better for fiber plant connectivity, while CX4 suits short legacy copper interconnects.
Is XENPAK-10GB-SR available new from ORM Systems?
XENPAK-10GB-SR new availability is limited because Cisco announced end of sale for 10GBASE XENPAK modules, with the last Cisco order date on September 30, 2015. ORM Systems can check remaining surplus, channel, or special-source availability. Buyers should confirm whether the requirement is new, refurbished, Cisco original, or compatible replacement before ordering.
Is XENPAK-10GB-SR available refurbished from ORM Systems?
XENPAK-10GB-SR can be requested from ORM Systems in certified refurbished condition when stock is available. Refurbished sourcing is common for legacy XENPAK optics because Cisco's sale and support dates have passed. ORM Systems can confirm module condition, connector inspection, identification, optical testing, warranty terms, and dispatch timing before the buyer commits.
How much does XENPAK-10GB-SR cost?
XENPAK-10GB-SR pricing depends on condition, stock source, quantity, Cisco original status, testing requirements, warranty cover, and delivery destination. Legacy XENPAK optics may vary in price because supply is driven by refurbished and surplus markets. ORM Systems can provide a current quote for single replacement modules, matched spares, or bulk legacy support orders.
Is XENPAK-10GB-SR end of life?
XENPAK-10GB-SR is end of sale and past Cisco's last date of support. Cisco announced end-of-sale and end-of-life dates for Cisco 10GBASE XENPAK modules on April 1, 2015. The last order date was September 30, 2015, the last ship date was December 29, 2015, and the last date of support was September 30, 2020.
What lead time should buyers expect for XENPAK-10GB-SR?
XENPAK-10GB-SR lead time depends on refurbished stock, testing queue, quantity, and delivery location. Because the module is a legacy end-of-support optic, availability can change quickly. ORM Systems can check current inventory, reserve tested units, confirm shipping options, and advise whether a Cisco original module or compatible replacement is more practical.
Are bulk discounts available for XENPAK-10GB-SR?
Bulk pricing for XENPAK-10GB-SR may be available when ORM Systems can source multiple tested units from refurbished or surplus inventory. Volume buyers should provide target quantity, acceptable condition, required delivery dates, and whether Cisco original modules are mandatory. Bulk purchases are useful for maintaining spares across legacy Catalyst 6500 or Cisco 7600 estates.
What warranty applies to XENPAK-10GB-SR from ORM Systems?
XENPAK-10GB-SR warranty terms from ORM Systems should be confirmed in the quotation because Cisco support for the XENPAK family has ended. Refurbished or surplus modules may carry reseller warranty rather than Cisco hardware support. Buyers should request written warranty duration, replacement process, testing coverage, and any exclusions related to legacy platform compatibility.
How is refurbished XENPAK-10GB-SR stock tested before dispatch?
Refurbished XENPAK-10GB-SR stock should be checked for module identification, clean dual SC connectors, physical latch condition, host recognition, stable 10G link operation, and optical transmit and receive behavior. Testing reduces risk from dirty connectors, damaged shells, marginal optics, or unsupported coding. ORM Systems can confirm the inspection process before dispatch.
What certifications and compliance standards apply to XENPAK-10GB-SR?
XENPAK-10GB-SR follows the 10GBASE-SR Ethernet optical application used with multimode fiber and the XENPAK module ecosystem. Project teams needing formal compliance evidence should request current documentation for the exact module supplied, especially for refurbished or surplus stock. Important checks include laser safety, EMC, RoHS position, and host platform acceptance.
How is XENPAK-10GB-SR installed?
XENPAK-10GB-SR installs by inserting the module into a compatible Cisco XENPAK port, securing the module latch, connecting dual SC multimode fiber, and checking link status on both ends. Engineers should clean fiber connectors, verify OM3 distance limits, confirm the far end uses 10GBASE-SR optics, and check platform logs for transceiver acceptance.
Does XENPAK-10GB-SR require software or licensing?
XENPAK-10GB-SR does not require a separate optic license, but the host Cisco platform must support the module, port type, and software release. Older Catalyst and routing platforms can have strict line card and software requirements. Buyers should confirm the exact chassis, supervisor, module, and operating system before ordering replacement XENPAK optics.
What cables and accessories are needed with XENPAK-10GB-SR?
XENPAK-10GB-SR requires duplex multimode fiber patching with dual SC connectors at the module end. OM3 fiber supports up to 300 m, while OM4 may support longer 400 m links where the design allows.
