Module Type and Purpose

The Transition Networks TN-SFP-GE-L-C is a small form-factor pluggable transceiver built for 1000Base-LX Gigabit Ethernet links. It targets network administrators extending fibre connections between switches, routers or servers across campus or metro distances.

Sustained Link Behaviour

The module maintains a continuous 1000 Mbps optical signal over single-mode fibre without the throughput drops seen in copper runs near their length limit. Laser-based transmission keeps latency stable during prolonged traffic loads such as backup windows or video streams.

Build and Connector Implications

A duplex LC receptacle locks securely into patch panels, reducing accidental disconnects during rack maintenance. The hot-pluggable SFP footprint lets technicians add or replace links without powering down the host chassis, cutting planned downtime.

Questions about this item

How much power does the TN-SFP-GE-L-C draw during continuous operation?

The module uses a standard SFP form factor with a single LC duplex 1000Base-LX interface, so power draw stays within the typical SFP envelope for all-day use.

What port type must my switch or router provide for this module to work?

You need an available SFP slot that accepts an LC duplex connector for the 1000Base-LX link.

Will this SFP link at gigabit speed with older 1000Base-LX gear I already own?

Yes, the 1000Base-LX standard ensures compatibility with other compliant LX equipment at 1000 Mbps.
