TN-GLC-SX-MM-RGD SFP transceiver

The Transition Networks TN-GLC-SX-MM-RGD is a small form-factor pluggable transceiver delivering 1 Gbps connectivity over multimode fibre. It suits network administrators extending Gigabit Ethernet or fibre channel links in enterprise or campus environments.

Compatibility and fibre checks

Verify that the host equipment accepts SFP modules and supports 1000BASE-SX optics at 850 nm. Ensure the link uses LC-terminated multimode cable and that the planned run does not exceed 550 metres.

Sustained-load behaviour

The module is rated for bidirectional serial-optical data communication at speeds up to 1.25 Gbps. It maintains the optical link continuously across the full 550 metre distance without relying on short-burst headroom.

Questions about this item

Does the TN-GLC-SX-MM-RGD include the LC duplex patch cable or must I order it separately?

The transceiver has LC duplex ports; the multimode patch cable is not included and must be purchased separately.

Should I choose this 850 nm SX model or a longer-reach LX version for my link?

Choose the 850 nm SX model when the multimode fibre run is 550 metres or less; select an LX module for longer single-mode distances.

What does the 1.25 Gbps line rate mean for actual throughput in a 1000BASE-SX link?

The 1.25 Gbps line rate carries 1000 Mbps of user data after 8b/10b encoding, delivering full gigabit Ethernet throughput over multimode fibre.
