STARTECH SFPGESST SFP Transceiver 1000BASE-SX

This module provides a 1 Gbps fibre link for network switches and routers. It targets administrators who need to extend a Gigabit Ethernet segment over multimode fibre. The SFP form factor fits standard SFP cages in compatible equipment. Buyers who require single-mode reach or 10 Gbps speeds cannot use this transceiver.

IEEE 802.3z 1000BASE-SX practical limits

The 850 nm wavelength operates over multimode fibre up to 550 m or 1804 ft. Data rates reach 1.25 Gbps within that distance. Beyond the stated range signal loss increases and link stability drops. The LC duplex connector mates only with LC patch cords; other connector types need a hybrid cable or adapter.

Hot-pluggable installation and common issues

The transceiver inserts into an SFP cage without powering down the host device. Compliance with MSA standards ensures mechanical fit in multi-vendor hardware. Cisco SFP-GE-S compatibility is guaranteed by the supplier. Failures usually stem from contaminated LC ferrules, mismatched fibre polarity or exceeding the 550 m distance budget.

Questions about this item

Which version of the SFPGESST should I choose for a 1 Gbps multimode link?

The module is a single 1000BASE-SX variant operating at 850 nm with a 1.25 Gbps data rate and 550 m reach on multimode fibre.

What does the 1.25 Gbps headline rate deliver in a live switch?

It provides a full 1 Gbps Ethernet throughput per port with hot-pluggable LC connectivity and MSA compliance for multi-vendor operation.

What interface standard does the LC connector use and what distance does it cap?

The LC duplex interface follows IEEE 802.3z 1000BASE-SX and SFP MSA standards, limiting reach to 550 m (1804 ft) on multimode fibre.
