Industrial copper SFP for extended temperatures

The STARTECH GLCTEST is a Cisco GLC-TE compatible transceiver that delivers 1.25 Gbps over Cat5e or Cat6 copper cable up to 100 m. It fits standard SFP slots in switches and routers and operates from -40°C to 85°C. The module is hot-swappable for simple installation without downtime.

Passive cooling with no moving parts

Because the transceiver contains no fan, it runs silently and draws minimal power during normal operation. The extended temperature rating of -40°C to 85°C means it stays within specification inside industrial enclosures or outdoor cabinets. No active airflow is required to maintain performance.

Stable throughput under continuous load

The copper link maintains 1000BASE-T line rate across the full 100 m distance without throttling during sustained traffic. Temperature extremes do not reduce the 1.25 Gbps transfer rate or introduce errors. The module remains reliable for always-on industrial and commercial deployments.

Questions about this item

How do I install the GLCTEST SFP transceiver in a Cisco switch without damaging the RJ45 port?

Insert the module into an empty SFP slot until it clicks; the hot-swappable design means the switch stays powered. Connect Cat5e or Cat6 patch cable to the RJ45 jack — avoid forcing the latch, which is the step most installers get wrong.

What maintenance will the GLCTEST transceiver need after deployment in an industrial cabinet?

No scheduled maintenance is required. Keep the RJ45 port dust-free and verify cable integrity periodically; the module itself has no moving parts or replaceable components.

At what ambient temperature does the GLCTEST reach its operating limit during continuous 1.25 Gbps traffic?

The rated operating ceiling is 85 °C (185 °F). Sustained loads at or above that temperature exceed the specified range and may cause link errors or shutdown.
