850 nm SFP transceiver for Gigabit links

The Transition Networks TN-GLC-SX-MM is a Small Form Factor Pluggable module that adds a 1000Base-SX optical interface to any SFP-equipped switch or router. It targets network engineers extending Gigabit Ethernet or Fibre Channel over multimode fibre at 850 nm wavelength.

Replaces fixed copper ports or older GBIC modules

This transceiver upgrades a copper-only SFP slot to short-range fibre without changing the host device. The jump is worth it when link distances exceed copper limits or when electromagnetic immunity is required in the installation environment.

Handles 1.25 Gbps bidirectional traffic over

The module operates at 850 nm with an LC duplex connector and complies with IEC 60825 Class 1 laser safety. It reaches its distance limit on standard multimode fibre; longer spans need a long-wavelength alternative.

Questions about this item

What SFP slot size and fiber connector does the TN-GLC-SX-MM need?

It fits a standard SFP slot and uses a duplex LC connector for multimode fiber.

How do I install the module and what step is often missed?

Slide the transceiver into the SFP port until it clicks, then insert the LC patch cable; the latch must click or the link will not come up.

What ongoing care or replacement does the 850 nm optic require?

Keep the LC ferrule clean with a lint-free wipe and isopropyl alcohol; replace the module if the optical budget drops below the 1.25 Gbps link requirement.
