Cisco-compatible 1000BASE-EX transceiver

The StarTech.com GLCEXSMDST is a hot-swappable SFP module built to the IEEE 802.3z 1000BASE-EX standard. It delivers a 1.25 Gbps Gigabit Ethernet link over single-mode fibre at a 1310 nm wavelength. Network engineers and integrators use it to extend Cisco and MSA-compliant switches across campus or metro distances up to 40 km (24.8 mi).

LC duplex interface and broad switch support

A single LC duplex female receptacle accepts standard single-mode patch cables for straightforward rack or cabinet installation. The module is coded for 100 percent Cisco GLC-EX-SMD compatibility and functions in platforms such as Firepower, ASR920, IE2000, IE4000 and ASR1000. It also operates in uncoded MSA switches from vendors including Ubiquiti, D-Link, Netgear, Supermicro and TP-Link.

Industrial temperature range and digital diagnostics

Rated for continuous operation from 0 °C to 70 °C (32 °F to 158 °F) with storage tolerance down to -40 °C and up to 85 °C, the transceiver suits demanding indoor environments. Built-in Digital Diagnostic Monitoring reports real-time status to SNMP management tools for proactive link health visibility. No moving parts means silent operation and minimal power draw.

Questions about this item

Does the 1000BASE-EX interface on this SFP module limit the link to 1.25 Gbps?

Yes, the IEEE 802.3z 1000BASE-EX standard sets the transfer rate at 1.25 Gbps over single-mode fibre.

What physical connector and fibre type does the GLCEXSMDST need to fit?

It uses an LC duplex female port and requires single-mode fibre patch cables.

How is this transceiver installed in a Cisco switch and what step is often missed?

Insert the hot-swappable module into an SFP slot until it clicks, then enable Digital Diagnostic Monitoring in your SNMP tool to read temperature and signal levels.
