Purpose-built network extender

The StarTech ET90110ST2 converts a 10/100 Mbps copper Ethernet link to multi-mode fiber with an ST connector, reaching 1.2 miles or 2 km. It is designed for installers who must bridge two network segments beyond the distance limit of twisted-pair cabling.

Standalone or rack-mount ready

A black metal enclosure houses one RJ-45 port and one ST fiber port, allowing desktop use or insertion into the ETCHS2U rackmount chassis. Link-loss forwarding and remote monitor status simplify troubleshooting, while full and half-duplex modes match existing switch configurations.

10/100 Mbps speed ceiling

The converter passes only Fast Ethernet rates, so it suits legacy cameras, access points or industrial gear but cannot carry gigabit traffic. Buyers who need higher throughput must select a different media converter.
