Compact 1000Base-SX SFP module

The Transition Networks TN-GLC-SX-MMD is a hot-pluggable SFP transceiver built for Gigabit Ethernet links over multi-mode fibre. It fits standard mini-GBIC slots in switches, routers or server NICs and uses an LC duplex connector. The module is RoHS and WEEE certified and carries a lifetime limited warranty.

Multi-mode reach and MSA compliance

Multi-mode fibre limits link distance compared with single-mode, so plan runs within the 1000Base-SX reach for your chosen cable grade. The MSA-compliant form factor ensures mechanical and electrical interoperability with any host that follows the same specification. Hot-plug capability allows insertion or removal without powering down the chassis.

Check slot type and fibre patch cords

Verify that the target equipment accepts SFP modules and not the larger SFP+ or GBIC form factors. Confirm the switch or NIC port is configured for 1000Base-SX speeds and that multi-mode patch cables with LC duplex terminations are available. The physical envelope measures 8.38 mm high, 13.21 mm wide and 55.37 mm deep, so ensure adjacent ports are not blocked.
