1000BASE-LX SFP Transceiver

The Transition Networks TN-SFP-GE-L is a small form-factor pluggable transceiver built for single-mode fibre networks. It delivers a 1 Gbps transfer rate over a 1310 nm wavelength with an LC duplex connector. The module is suited for network administrators extending Gigabit Ethernet or fibre channel links up to 10 km.

Replaces copper uplinks or shorter-reach optics

This transceiver upgrades connections that currently run over copper or multi-mode fibre when distance exceeds their practical limit. The jump is worth it when a link must span up to 10 km without signal regeneration. It is not for buyers who need multi-mode compatibility or reaches beyond the specified single-mode distance.

Hot-pluggable SFP installation

The module installs into any standard SFP port without powering down the host switch or router. It operates at 3.3 V and weighs 0.15 units for lightweight handling. The most common issue is mismatching the LC connector polarity or using multi-mode patch cords instead of the required single-mode fibre.

Questions about this item

Does the LC duplex connector on this transceiver fit a standard SFP cage without an adapter?

Yes, the TN-SFP-GE-L uses an industry-standard LC duplex interface that plugs directly into any compliant SFP port.

What is the correct insertion sequence to avoid damaging the 1310 nm optical interface?

Insert the module into the SFP cage until it clicks, then connect the LC patch cable; never connect cables before the module is fully seated.

When should the optical interfaces be cleaned to maintain the 10 km link budget?

Clean both the transceiver LC ports and the patch-cord ferrules with a lint-free swab and isopropyl alcohol before first installation and whenever signal loss is detected.
