GLC-LX-SM-RGD is a Cisco rugged optical transceiver in the Small Form-Factor Pluggable form factor for Gigabit Ethernet ports. The hot-swappable hardware plugs into compatible Cisco Gigabit Ethernet interface slots without replacing the host chassis. This module provides 1 Gbps operation for 1000BASE-LX/LH Ethernet links where the platform accepts Cisco optics. Single-mode and multimode fiber are supported as the documented optical media options for LX/LH operation across existing cable plants. A dual LC/PC connector terminates the two-strand optical interface and preserves duplex transmit and receive separation. The 1310 nm wavelength handles transmit and receive optical operation within Cisco's LX/LH optical specification. Cisco specifies a 10 km maximum distance over standard single-mode fiber infrastructure under documented cabling conditions. Industrial operating temperature class applies to this rugged optic for matching in non-commercial operating spaces. Digital Optical Monitoring reports temperature, voltage, bias current, transmit power, and receive power on supported host platforms.
TX power range delivers -9.5 dBm minimum to -3 dBm maximum optical output. RX sensitivity receives compliant operation down to -20 dBm. Receiver overload point accepts -3 dBm as the maximum receive input. GLC-LX-SM-RGD follows IEEE 802.3z for the 1000BASE-LX optical Ethernet standard. SFF-8472 telemetry applies through the monitoring functions reported by compatible Cisco platforms. At 8b/10b encoding, the optical path carries Ethernet symbols across the physical layer. Power consumption stays within Cisco's typical 1 W per port envelope. Minimum port distance is 2 m across the listed fiber-port entries. Channel insertion loss reaches 6 dB on G.652 single-mode paths. A 2.4 dB maximum channel insertion loss applies on any multimode path. Both receiver power and channel insertion loss meet the specified optical operating limits. The ordering table pairs this product number with long-wavelength rugged hardware. Cisco's temperature table assigns IND operation and monitoring availability to this exact part number.
Cisco Catalyst 2960-X, Catalyst 3560-X, Catalyst 3750-X, and Catalyst 3850 families accept supported 1G SFP optics. Catalyst 4500-X, Nexus 9000, ASR 1000, IE2000, and IE3010 platforms also use supported 1G SFP optics. Deployment roles include industrial access, enterprise campus uplinks, aggregation handoffs, edge router connections, and metro extension points. Aggregation teams place the optic at uplink boundaries where rugged endpoints meet managed Cisco infrastructure. OS2 supports the long outside-plant or campus run when the optical budget matches the link. OM1 and OM2 require mode-conditioning planning for legacy short runs. Campus teams use it for repeatable rugged uplink spares. Buy GLC-LX-SM-RGD from ORM Systems in new and certified refurbished condition.

GLC-LX-SM-RGD sits in a Cisco industrial access switch and carries a 1G 1000BASE-LX/LH uplink from a remote cabinet toward the aggregation layer. The module uses 1310nm optics over single-mode fiber for spans up to 10km, with dual LC connectivity at the patch panel. Network teams monitor receive power and module temperature through DOM on supported platforms. The industrial temperature rating keeps the optic aligned with rugged access equipment in uncontrolled spaces, giving the access layer a stable long-reach fiber handoff.
GLC-LX-SM-RGD terminates a 1G fiber link between an access switch and a distribution switch where the cable plant uses single-mode fiber. Engineers place the optic in a supported Cisco SFP port, patch the dual LC strands through the fiber tray, and validate optical levels before enabling production traffic. The 1000BASE-LX/LH standard keeps the handoff consistent with Cisco Gigabit Ethernet uplink designs. The network gains a predictable 10km access-to-distribution path without changing copper endpoint cabling.
Operations teams standardize GLC-LX-SM-RGD as the rugged 1G LX/LH spare for Cisco sites that use single-mode uplinks in harsher temperature conditions. The module reports DOM values on supported platforms, so engineers compare transmit power, receive power, temperature, voltage, and laser bias during fault isolation. Its dual LC 1310nm design matches established two-strand fiber patching practices. The spares model reduces mixed optic handling and gives support teams a consistent replacement part for rugged 10km Gigabit Ethernet links.

Cisco GLC-LX-SM-RGD is a rugged 1000BASE-LX/LH SFP transceiver module for Gigabit Ethernet fiber links. It uses 1310nm optics, supports up to 10km over single-mode fiber, uses a dual LC connector, and includes Digital Optical Monitoring. The industrial temperature rating makes it suitable for Cisco networks deployed outside normal commercial operating conditions.
GLC-LX-SM-RGD identifies a Cisco Gigabit Ethernet SFP optic built for LX/LH single-mode fiber applications with a rugged industrial rating. GLC refers to Cisco Gigabit SFP optics, LX/LH identifies the 1000BASE-LX/LH optical standard, SM points to single-mode fiber use, and RGD separates this module from standard commercial or extended-temperature versions.
GLC-LX-SM-RGD is an optical transceiver, not a switch, router, or media converter. It plugs into a compatible Cisco SFP port and provides the optical interface for a 1 Gigabit Ethernet fiber link. The module does not perform switching or routing by itself, because forwarding remains handled by the host Cisco platform.
GLC-LX-SM-RGD sits in Cisco's 1G SFP optic family as the rugged 1000BASE-LX/LH option for longer fiber links. It is positioned beside standard models such as GLC-LH-SMD and rugged multimode options such as GLC-SX-MM-RGD. Buyers choose it when a Cisco 1G SFP port needs LX/LH reach with industrial temperature tolerance.
GLC-LX-SM-RGD uses the Small Form-Factor Pluggable SFP form factor for Gigabit Ethernet interfaces. It is hot-swappable in supported Cisco SFP slots, allowing the host platform to accept fiber media on a port-by-port basis. The SFP format makes it suitable for access, distribution, router, industrial Ethernet, and service-provider edge equipment with compatible 1G SFP ports.
GLC-LX-SM-RGD supports 1 Gigabit Ethernet operation using the 1000BASE-LX/LH optical standard. It is intended for 1G SFP ports rather than 10G SFP+ or 25G SFP28 interfaces. Compatibility should be checked against the exact Cisco platform and software release, because host devices determine which optic part numbers are accepted.
GLC-LX-SM-RGD operates at 1310nm for 1000BASE-LX/LH fiber links. This wavelength is commonly used for long-wavelength Gigabit Ethernet optics over single-mode fiber. Cisco specifies the LX/LH optical category for both single-mode fiber up to 10km and multimode fiber up to 550m when the fiber plant is built correctly.
GLC-LX-SM-RGD supports up to 10km over standard single-mode fiber and up to 550m over multimode fiber under the 1000BASE-LX/LH specification. For legacy multimode fiber, a mode-conditioning patch cord is normally required. Buyers should validate fiber type, connector polish, patching, and link budget before ordering optics for an existing cable plant.
GLC-LX-SM-RGD uses a dual LC/PC connector for two-strand fiber operation. One strand transmits and the other receives, so it is not a single-fiber bidirectional optic. Patch cords should use compatible LC connectors and the correct fiber type for the intended link, such as single-mode fiber for 10km LX/LH connections.
GLC-LX-SM-RGD supports Digital Optical Monitoring, often shortened to DOM. DOM allows supported Cisco platforms to read optical parameters such as temperature, transmit power, receive power, voltage, and laser bias current. This is useful for troubleshooting fiber links, checking degraded optics, and confirming whether received optical power sits within the expected operating range.
GLC-LX-SM-RGD is used for 1G fiber uplinks between compatible Cisco switches, routers, or industrial Ethernet devices. It fits access-to-distribution links, remote cabinet connections, industrial network uplinks, and long building-to-building fiber runs. The rugged industrial temperature rating makes the SKU useful where the host equipment sits in harsher operating environments than a normal office closet.
GLC-LX-SM-RGD fits networks that need a single 1G optical handoff across campus, industrial, utility, transport, or remote access locations. The 10km single-mode reach supports longer fiber paths than short-reach multimode optics. It is not selected by site size alone, because the real design factors are host compatibility, fiber type, distance, and temperature conditions.
GLC-LX-SM-RGD suits normal Gigabit Ethernet traffic carried across a fiber uplink, including management traffic, access-layer aggregation, industrial device connectivity, IP camera backhaul, controller links, and remote switch uplinks. It does not add bandwidth beyond 1G. The value of the module is the 1000BASE-LX/LH optical handoff over longer fiber distance with industrial temperature operation.
GLC-LX-SM-RGD is suitable for industrial Cisco deployments where the connected platform supports this rugged SFP. Cisco lists the module with an industrial temperature range and DOM support, making it better suited than commercial optics for cabinets, remote enclosures, and uncontrolled spaces. The surrounding switch, power, enclosure, and cabling must also meet the site's environmental requirements.
GLC-LX-SM-RGD is supported across many Cisco platforms that accept 1G SFP optics, including selected Catalyst, Cisco IE, Cisco ME, Nexus, ASR, ISR, ASA, and MDS families. Exact compatibility depends on the host model and software version. Buyers should match the SKU against Cisco's transceiver compatibility matrix before installation in a specific switch or router.
GLC-LX-SM-RGD is commonly selected for Cisco Industrial Ethernet environments when the switch model supports rugged 1G SFP optics. Cisco IE platforms such as IE2000 and IE3010 appear within Cisco's broader 1G SFP support ecosystem. The exact IE switch model, software image, and supported optic table should be checked before purchase.
GLC-LX-SM-RGD is aligned with the 1000BASE-LX/LH Gigabit Ethernet optical standard and IEEE 802.3z 1000BASE-LX operation. It uses 1310nm transmission, dual LC fiber connectivity, and supports single-mode fiber up to 10km. Multimode fiber use is possible within LX/LH rules, but legacy MMF generally requires a mode-conditioning patch cord.
GLC-LX-SM-RGD should connect to an optical peer using matching 1000BASE-LX/LH parameters, 1310nm wavelength, compatible receive power range, dual LC fiber polarity, and the same link speed. The opposite end does not have to be the identical SKU in every design, but the optical standard, fiber type, and host compatibility must align.
GLC-LX-SM-RGD and GLC-LH-SMD are both Cisco 1000BASE-LX/LH 1G SFP optics with 1310nm operation, dual LC connectivity, 10km SMF reach, and DOM support. The key difference is environmental rating. GLC-LX-SM-RGD is the rugged industrial-temperature option, while GLC-LH-SMD is the extended-temperature standard LX/LH option for less demanding environments.
GLC-LX-SM-RGD is the rugged long-wavelength LX/LH optic for 10km single-mode links, while GLC-SX-MM-RGD is the rugged short-wavelength SX optic for multimode fiber. Both are Cisco rugged 1G SFP modules with DOM support, but they serve different fiber plants. GLC-LX-SM-RGD fits longer SMF runs, while GLC-SX-MM-RGD fits short MMF connections.
GLC-LX-SM-RGD is the rugged 1000BASE-LX/LH option for up to 10km over single-mode fiber. GLC-ZX-SM-RGD is the rugged extended-distance 1000BASE-ZX option for much longer single-mode links, around 70km depending on link loss. The correct choice depends on fiber span, optical budget, attenuation requirements, and host support.
GLC-LX-SM-RGD is a rugged 1000BASE-LX/LH SFP for 1G industrial-temperature deployments. GLC-GE-DR-LX is a Cisco dual-rate 100M/1G LX SFP with DOM for designs that require 100M and 1G interoperability. GLC-LX-SM-RGD is the better fit when the design requires rugged 1G LX/LH operation rather than dual-rate behavior.
GLC-LX-SM-RGD is typically sourced through enterprise hardware channels in new, used, or refurbished condition depending on market availability. ORM Systems lists products for B2B buyers that need Cisco optics for maintenance, replacement, and project requirements. Availability should be confirmed at quote stage because rugged Cisco SFP demand and supply can change quickly.
GLC-LX-SM-RGD price is influenced by condition, quantity, lead time, original Cisco availability, testing requirements, and whether the order is for urgent replacement or planned rollout stock. Rugged industrial optics often price differently from standard commercial-temperature optics. Buyers comparing quotes should check whether DOM support, warranty terms, and genuine Cisco sourcing are included.
GLC-LX-SM-RGD availability depends on Cisco lifecycle status, channel stock, and secondary-market supply at the time of purchase. Even when a Cisco optic becomes harder to source new, refurbished or surplus units may still be available for installed-base support. Buyers should confirm current lifecycle, lead time, and acceptable condition before committing to a deployment plan.
GLC-LX-SM-RGD lead time depends on required condition, quantity, testing status, and destination. Single replacement units may be easier to source than larger rollout quantities, especially for rugged industrial optics. ORM Systems can quote based on current sourcing options, but buyers should provide required delivery date, acceptable condition, and target quantity for accurate availability.
Bulk pricing may be available for GLC-LX-SM-RGD when multiple units are ordered for spares, staged upgrades, industrial rollouts, or distributed site refreshes. Quantity, condition, sourcing route, and warranty expectations affect the final quote. Buyers should include target quantity and required delivery timeline so ORM Systems can check volume pricing across available supply.
GLC-LX-SM-RGD may be supplied with warranty coverage depending on condition, source, and quoted terms. ORM Systems product copy commonly supports up to a 3-year warranty for tested optics where applicable. Buyers should review the quote for the exact warranty period, replacement process, and any condition-specific coverage before placing an order.
Refurbished GLC-LX-SM-RGD modules should be tested before dispatch to confirm identification, link operation, DOM visibility where supported, and acceptable optical performance. Testing is especially important for rugged optics deployed in industrial environments because replacement windows may be limited. Buyers should request confirmation of testing standards and warranty coverage when ordering refurbished units.
GLC-LX-SM-RGD follows the 1000BASE-LX/LH Gigabit Ethernet optical standard and uses the Cisco SFP form factor for supported Cisco platforms. Cisco specifies dual LC/PC connectivity, 1310nm operation, DOM support, and industrial temperature rating for this SKU. Compliance should be reviewed against the host equipment, project standard, and regional procurement requirements.
GLC-LX-SM-RGD installs into a compatible Cisco 1G SFP port, then connects to a dual LC fiber patch cord. The fiber pair should be matched for transmit and receive polarity, and the far-end optic should use compatible 1000BASE-LX/LH parameters. After insertion, the host platform should report the optic and link state correctly.
GLC-LX-SM-RGD does not require a separate software licence because it is a physical SFP transceiver. The host Cisco switch or router must still run a software release that supports the optic. Platform licensing, port enablement, and feature configuration remain separate considerations handled on the switch, router, or network operating system.
GLC-LX-SM-RGD normally requires a compatible Cisco SFP port and a dual LC fiber patch cord matched to the link design. Single-mode fiber is used for 10km LX/LH links. Multimode deployments may require mode-conditioning patch cords. Technicians may also use fiber cleaning tools, optical power meters, and documentation from the host platform during installation.
UK buyers can purchase GLC-LX-SM-RGD through ORM Systems for Cisco hardware sourcing, replacement optics, and project-based procurement. ORM Systems can quote based on required quantity, condition, warranty expectation, and lead time. Buyers should provide the target Cisco platform and fiber distance so the correct rugged LX/LH SFP is matched to the requirement.
ORM Systems supports international B2B hardware sourcing and can quote GLC-LX-SM-RGD for buyers outside a single local market. Shipping options depend on destination, stock location, quantity, customs requirements, and delivery urgency. International buyers should confirm import details, required documentation, and acceptable delivery timeline during the quote process.
