Network transceiver for Gigabit links

The Transition Networks TN-GLC-LH-SMD is a hot-pluggable SFP module built for 1000Base-LX Gigabit Ethernet over single-mode fiber. It suits network administrators extending campus or metro links between switches, routers or servers. The MSA-compliant design fits any standard SFP port without proprietary lock-in.

Duplex LC connector and single-mode reach

A duplex LC interface carries transmit and receive fibers in one compact latch, simplifying patch-panel density. The module operates on 50/125 µm single-mode cable at up to 1.25 Gbps, supporting long-haul runs where multi-mode cannot reach. Hot-swap capability means links stay live during upgrades or maintenance.

Verify SFP port and fiber plant before ordering

Confirm the host device accepts MSA-compliant SFP transceivers and runs 1000Base-LX optics, not 1000Base-SX or copper. Ensure your patch cables are single-mode with LC duplex terminations and that link budgets match the intended distance. RoHS and WEEE compliance meet common environmental mandates.
