SFP-10G-LR is a Cisco SFP+ optical transceiver with 10 Gbps Ethernet operation for host interfaces. The module uses single-mode fiber as its optical transmission media for long-reach hardware connectivity inside pluggable optical links. Its port side uses a Dual LC/PC connector for supported PC or UPC patch cords. The transmit and receive wavelength is 1310 nm across the LR optical lane. The maximum supported link length is 10 km on standard G.652 cabling for LR operation. The operating temperature class is Commercial for standard equipment-room and controlled-rack thermal conditions. Digital optical monitoring reports optical output power, optical input power, temperature, laser bias current, and transceiver voltage. Hot-swappable input/output construction allows insertion and replacement without powering down the connected Cisco host platform. Cisco quality identification enables compatible Cisco platforms to recognise certified and tested Cisco optics during module insertion and inventory checks.
SFP-10G-LR delivers transmit power from -8.2 dBm minimum to 0.5 dBm maximum average output. RX sensitivity provides -14.4 dBm minimum receive performance under Cisco LR optical characteristics. RX overload sits at 0.5 dBm maximum receive power for the LR receiver path. IEEE 802.3ae governs 10-Gigabit Ethernet operation and the two-meter minimum LR cabling distance. SFF-8431 applies to optical modules, active optical cables, and passive twinax assemblies. GR-20-CORE addresses optical fiber and optical fiber cable requirements for related physical infrastructure. GR-326-CORE addresses optical connector and jumper assembly requirements across optical paths. GR-1435-CORE addresses multifiber optical connector requirements within the same standards set. ITU-T G.709 applies to Optical Transport Network interface requirements. ITU-T G.975 applies to generic forward error correction requirements. ITU-T G.975.1 applies to enhanced forward error correction requirements. With 1 W maximum consumption, the module fits low-power port budgets. The optical power values use average dBm measurements rather than OMA measurements.
Compatible platform families include Cisco ASR 1000, ASR 9000, Catalyst 2960-X, Catalyst 3560-X, Catalyst 3750-X, and Catalyst 3850. Additional families include Catalyst 4500-X, Nexus 2000, Nexus 3000, Nexus 9000, MDS 9000, and UCS switching platforms. Deployment roles include data centre interconnect, enterprise campus backbone, aggregation, service provider transport, and storage Ethernet fabrics. Campus backbone roles place LR optics between building distribution and core switching layers. Aggregation roles use the optic for northbound 10G handoffs between Cisco switching tiers. G.652-class infrastructure aligns with the specified LR optical path. Buy SFP-10G-LR from ORM Systems in new and certified refurbished condition.

SFP-10G-LR occupies the 10G optical handoff between an access switch uplink slot and a distribution switch SFP+ port. Engineers connect duplex LC single-mode fiber, pair the far end with a compatible 10GBASE-LR optic, and keep the path within the 10km LR reach. The 1310nm link carries aggregated access traffic northbound while DOM readings expose optical power and temperature on supported Cisco platforms. This placement fits access closets that already terminate single-mode riser or campus fiber. The result is a verified long-reach access uplink that avoids replacing existing single-mode cabling.
The transceiver operates at the campus distribution layer where 10G links feed core switches across building fiber. Network teams place Cisco SFP-10G-LR in SFP+ interfaces, patch LC single-mode runs through the fiber plant, and validate the optical budget before enabling trunks or routed links. The 10GBASE-LR standard keeps the 1310nm connection aligned with common SMF infrastructure up to 10km. Engineers reserve ER and ZR optics for paths beyond the LR distance class. The result is predictable distribution-to-core capacity across longer campus paths.
SFP-10G-LR serves as a standardized spare for teams maintaining Cisco 10GBASE-LR links across Catalyst, Nexus, router, or module-based SFP+ ports. Operations teams label the spare against 10km SMF use, LC patching, DOM visibility, and FCoE requirements, then reserve SR, ER, and LR-X optics for different distance or temperature cases. A tested Cisco SFP-10G-LR replaces failed LR modules without changing fiber type, connector style, or link design. The spare pool keeps identical 1310nm LR behavior across repeated replacements. The result is faster restoration for established 10G single-mode uplinks.

Cisco SFP-10G-LR is a 10GBASE-LR SFP+ optical transceiver for 10 Gigabit Ethernet links over single-mode fiber. It uses a 1310nm wavelength, supports up to 10km reach on standard G.652 SMF, and uses an LC connector. Network teams use it for longer 10G fiber uplinks where multimode SR optics do not provide enough distance.
SFP-10G-LR identifies a Cisco SFP+ transceiver for 10 Gigabit Ethernet long-reach optical links. The SFP portion refers to the pluggable transceiver family, 10G indicates 10Gbps Ethernet operation, and LR refers to long reach. For this SKU, long reach means 10km over standard single-mode fiber using a 1310nm optical wavelength.
SFP-10G-LR is an SFP+ transceiver, not a 1G SFP module. The SFP+ form factor supports 10Gbps links and fits compatible Cisco SFP+ ports on switches, routers, and network modules. It should be matched with 10G-capable host ports rather than older 1G-only SFP slots during network design and procurement.
SFP-10G-LR sits in the Cisco 10GBASE SFP+ optics family as the standard 10km single-mode option. It sits above short-reach SFP-10G-SR for distance and below longer-reach options such as SFP-10G-ER and SFP-10G-ZR. It is commonly selected when existing fiber plant uses duplex single-mode runs between network rooms or buildings.
SFP-10G-LR uses the SFP+ form factor for 10Gbps optical Ethernet connectivity. The module plugs into compatible Cisco SFP+ cages and provides a removable optical interface, which allows network teams to match the same switch or router port to the required fiber reach, wavelength, and connector type.
Cisco SFP-10G-LR supports 10 Gigabit Ethernet operation as a 10GBASE-LR optical module. It is intended for 10Gbps uplinks, distribution links, aggregation links, and compatible server or storage fabric handoffs where Cisco platform support is confirmed. It is not a 1G optical transceiver and should be ordered for 10G SFP+ interfaces.
SFP-10G-LR uses a 1310nm optical wavelength, which is standard for 10GBASE-LR transmission over single-mode fiber. This wavelength supports longer reach than 850nm short-reach multimode optics. Engineers should match the optic with suitable single-mode patch leads, cleaned fiber connectors, and a compatible 10GBASE-LR transceiver at the far end.
SFP-10G-LR supports up to 10km link length over standard G.652 single-mode fiber. The actual working link still depends on fiber quality, splice loss, connector cleanliness, and optical budget across the path. For distances beyond 10km, Cisco SFP-10G-ER or SFP-10G-ZR is normally reviewed instead of stretching the LR design.
SFP-10G-LR uses an LC optical connector, typically deployed with duplex LC single-mode patch leads. The connector choice matters during ordering because it must match patch panels, fiber trays, and the remote optic. Network teams should confirm LC polarity and fiber cleanliness before bringing the 10G link into service.
SFP-10G-LR supports DOM, also called digital optical monitoring, on compatible Cisco platforms and software. DOM helps operations teams view optical transmit power, receive power, temperature, voltage, and bias current where the host platform exposes those values. This visibility supports troubleshooting for dirty connectors, high fiber loss, and marginal long-distance 10G links.
SFP-10G-LR is used for 10Gbps fiber links that need more distance than multimode short-reach optics provide. Common placements include access-to-distribution uplinks, distribution-to-core links, building-to-building fiber, and 10G handoffs between Cisco network devices. Its 10km single-mode reach makes it useful where duplex SMF already exists in the cabling plant.
SFP-10G-LR suits environments that need 10G connectivity across wiring rooms, floors, buildings, or campus fiber routes. It is not sized by user count like a switch or firewall. The practical fit depends on 10G port availability, single-mode fiber routes, distance, and the bandwidth requirement between connected Cisco devices.
Cisco SFP-10G-LR links suit traffic that needs stable 10Gbps transport across longer fiber paths, including uplink aggregation, inter-switch traffic, virtualization clusters, storage network handoffs, backup movement, and routed campus links. The SKU provides the optical layer for the connection, while throughput behavior depends on the connected platforms and network design.
SFP-10G-LR is commonly used for building-to-building 10G links when the route uses standard single-mode fiber and the optical path stays within the 10km LR reach. Engineers still validate patch panels, splice trays, fiber loss, and grounding or pathway design separately. The transceiver provides the 10G optical endpoint, not the outside plant design.
SFP-10G-LR is supported across selected Cisco platforms with compatible 10G SFP+ interfaces, including many Catalyst, Nexus, ASR, ISR, and network module options. Exact support depends on the host hardware and software release. The Cisco Optics Compatibility Matrix should be checked before ordering SFP-10G-LR for a specific switch or router.
SFP-10G-LR works with supported Cisco Catalyst switches that have compatible 10G SFP+ ports or uplink modules. Examples often reviewed include Catalyst access, distribution, and core platforms with SFP+ uplink capability. Buyers should confirm the exact Catalyst model, network module, and IOS XE release in the Cisco Optics Compatibility Matrix.
SFP-10G-LR is used with supported Cisco Nexus platforms that expose compatible 10G SFP+ interfaces. It is often considered for data center leaf, aggregation, and storage-adjacent network links over single-mode fiber. Compatibility should be validated against the exact Nexus model, NX-OS release, and port mode before deployment.
SFP-10G-LR is tied to 10GBASE-LR Ethernet operation over single-mode fiber and is listed by Cisco as supporting FCoE in the provided product context. The link should be paired with another compatible 10GBASE-LR optic on the far end. Platform support, DOM exposure, and protocol behavior depend on the Cisco host device.
SFP-10G-LR is the single-mode 10km option, while SFP-10G-SR is the short-reach multimode option for shorter fiber runs. SFP-10G-SR uses multimode fiber and is usually selected inside a rack, row, or nearby network room. SFP-10G-LR is selected when the 10G link crosses longer campus or building fiber paths.
SFP-10G-LR and SFP-10G-LR-S both target 10GBASE-LR links up to 10km over single-mode fiber. The S-Class SFP-10G-LR-S is positioned for Ethernet-only applications and Cisco notes that the S-Class LR-S variant does not support FCoE. SFP-10G-LR is the better match where the specified order requires FCoE support.
SFP-10G-LR is the standard 10GBASE-LR 10km SFP+ transceiver, while SFP-10G-LR-X is the extended temperature LR variant. Both use single-mode fiber for 10km links, but SFP-10G-LR-X is reviewed when the installation environment requires wider operating temperature tolerance. Standard indoor network rooms usually use SFP-10G-LR unless conditions require otherwise.
SFP-10G-LR supports 10km single-mode links, while SFP-10G-ER extends reach to 40km and SFP-10G-ZR is used for much longer 10G single-mode distances. LR is usually the practical choice for campus and building links within 10km. ER or ZR should be reviewed when the measured optical path exceeds LR distance limits.
SFP-10G-LR pricing depends on condition, quantity, sourcing route, and current market availability. New, refurbished, and surplus Cisco optics can price differently, especially for bulk network refresh orders. ORM Systems can provide a current SFP-10G-LR quote based on required quantity, delivery location, warranty preference, and whether matching optics are needed.
SFP-10G-LR may be sourced in new, refurbished, or surplus condition depending on current supply. Refurbished optics are often attractive for Cisco network expansions where the buyer needs genuine compatibility at lower cost. The correct condition should be confirmed at quote stage so procurement, warranty, and project timing match the deployment requirement.
Cisco SFP-10G-LR has been widely deployed for many years, and lifecycle status should be checked against Cisco announcements for the exact part and region. Even where lifecycle changes affect new supply, refurbished and secondary-market availability often remains important for maintaining existing Catalyst, Nexus, ASR, and ISR deployments using 10G SFP+ optics.
SFP-10G-LR lead time depends on required quantity, condition, and whether the order needs Cisco-original sealed, refurbished, or tested surplus units. Small quantities can often move faster than large matched batches. Buyers should request current lead time with the quote, especially when optics are tied to a cabling cutover or switch refresh window.
Bulk pricing is often available for SFP-10G-LR when buyers need multiple optics for switch refreshes, campus uplinks, spare kits, or standardized 10G rollouts. Quantity, condition, and delivery timing affect the final price. ORM Systems can quote volume pricing for matched batches where procurement needs consistent Cisco part numbers and warranty coverage.
ORM Systems offers warranty coverage on eligible SFP-10G-LR orders, with coverage depending on condition, sourcing route, and quote terms. For optics, buyers should confirm warranty length, replacement process, and whether the order includes tested refurbished or new units. Clear warranty terms help reduce risk when buying transceivers for production 10G links.
Refurbished SFP-10G-LR modules should be tested for recognition, link operation, optical transmit and receive behavior, and DOM readings where suitable test platforms are available. Practical checks help confirm that the module identifies correctly and supports a stable 10GBASE-LR link. Buyers should ask for tested units when the optics are going into production networks.
SFP-10G-LR aligns with 10GBASE-LR Ethernet operation for 10Gbps links over single-mode fiber. It is also part of the SFP+ optical module ecosystem used in Cisco qualified host platforms. Buyers should confirm any required regulatory, safety, or organizational compliance documents at quote stage, especially for controlled procurement environments.
SFP-10G-LR is installed by inserting the module into a compatible Cisco 10G SFP+ port, connecting duplex LC single-mode fiber, and bringing up the interface with the correct speed and configuration on the host device. Engineers should clean fiber ends, verify polarity, check link status, and review DOM readings after the connection comes online.
SFP-10G-LR does not require a separate transceiver licence by itself. The host Cisco platform must support the optic, the port speed, and any required feature licensing for the connected service. Software release compatibility remains important because Cisco optics support and DOM visibility are tied to the host platform and operating system.
SFP-10G-LR normally requires duplex LC single-mode patch leads, a compatible 10GBASE-LR optic at the far end, available SFP+ ports, and a fiber path within the optical budget. Fiber cleaning tools, inspection scope access, and patch panel labeling are also useful during installation because connector contamination is a common cause of marginal 10G optical links.
UK buyers can purchase Cisco SFP-10G-LR through ORM Systems for Cisco network upgrades, replacement optics, spare kits, and bulk 10G rollout projects. The quote should specify quantity, desired condition, warranty preference, and delivery deadline. This helps match available stock or sourcing options with the buyer's deployment schedule.
ORM Systems can support international sourcing requests for SFP-10G-LR, subject to availability, export requirements, carrier options, and destination rules. International buyers should include delivery country, required quantity, condition preference, and target timeline in the enquiry. Clear shipping details help confirm freight cost, lead time, and documentation requirements before order placement.
