Compatible Gigabit SFP module

This StarTech.com GLCLHSMDST transceiver delivers 1.25 Gbps over single-mode or multi-mode fiber at 1310 nm. It meets IEEE 802.3z 1000BASE-LX/LH standards and reaches 10 km on single-mode cable. The LC duplex connector fits standard SFP cages and the module is fully compatible with Cisco GLC-LH-SMD equipment. Digital Diagnostic Monitoring reports transceiver health to SNMP tools.

Suited for Cisco and MSA switches

Network engineers extending campus or metro links between Cisco Firepower, ASR or IE switches will find this module a direct replacement. Builders using Ubiquiti, Netgear or other MSA-compliant gear that accepts uncoded SFPs can also deploy it. It is not suited for links longer than 10 km or for multi-mode runs that exceed the standard reach. Buyers needing 10 Gbps or 25 Gbps speeds must select a different form factor.

Deciding specification: 10 km single-mode reach

The 10 km maximum distance on single-mode fiber at 1310 nm is the figure that confirms whether this transceiver matches the link budget. Verify the patch length and fiber type before ordering. Operating temperature spans 0 °C to 70 °C with storage down to -40 °C. Humidity tolerance is 5 to 95 percent RH. Weight is 0.15 units.

Questions about this item

How do I install the GLCLHSMDST SFP transceiver into a Cisco switch, and what step do people often miss?

Insert the module into an SFP slot until it clicks, then lock the LC duplex cables by pushing the connector until the latch engages; the step people miss is removing the dust caps from both the transceiver and the fiber ends before connecting.

What maintenance will the GLCLHSMDST transceiver need over its lifetime?

Periodically inspect and clean the LC duplex fiber connectors with a lint-free wipe and isopropyl alcohol to prevent signal loss from dust or oil; no internal components require replacement.

At what operating temperature does the GLCLHSMDST transceiver hit its thermal limit during sustained use?

The module is rated for continuous operation up to 70 °C; exceeding this temperature can cause errors or shutdown before any other limit is reached.
