  • 850 nm wavelength reaches 550 metres
  • Hot-swappable module installs without network downtime

1 Gbps SFP Transceiver for Multi-Mode Fiber

This MSA-uncoded SFP module delivers a 1 GbE link over 850 nm multi-mode fiber with an LC duplex connector. It complies with IEEE 802.3z 1000BASE-SX and supports Digital Diagnostic Monitoring for real-time status reporting via SNMP tools.

Replaces Vendor-Locked 1G SFP Optics

Use this module to replace proprietary transceivers in MSA-compliant switches and routers from brands such as Ubiquiti, D-Link, Netgear, Supermicro and TP-Link. The upgrade is worthwhile when you need hot-swappable 1 Gbps connectivity up to 550 m without paying OEM pricing or risking warranty conflicts.

Verify Switch Accepts Uncoded Modules

Confirm your networking equipment supports third-party MSA optics and provides an available SFP cage. Ensure you have multi-mode fiber patch cables with LC duplex terminations rated for 850 nm operation. The unit operates from 0 to 70 °C and stores from -40 to 85 °C in 5 to 95 % RH environments.

Questions about this item

What type of fiber connector does the SFP1000SXST transceiver use?

The module has one LC duplex female port for multi-mode fiber patch cables.

How is the transceiver installed and what step is often missed?

Insert the hot-swappable module into an MSA-compliant SFP slot until it clicks; the step often missed is removing the dust caps from both the module and the fiber cable before connecting.

When should the SFP1000SXST be replaced based on its monitoring data?

Use the Digital Diagnostic Monitoring (DDM) via SNMP to track optical power and temperature; replace the module if received power drops below the link budget for 550 m or if operating temperature exceeds 70 °C.
