Your fiber run stretches further than the copper switch can reach. Or you've got a fiber drop at a remote site and need a clean RJ45 handoff for the gear sitting on the desk. The MC110CS does that one job properly: converts 100BASE-FX single-mode fiber to 100Base-TX copper, or vice versa, out to 20 kilometres. No software to configure, no driver to hunt down. Plug it in, watch the Link/Act LED go solid, and your network's back. It handles half or full duplex on the FX port so you match whatever the far end is running. Link Fault Passthrough and Far End Fault reporting keep you from chasing a dead link at 7am when the whole site is down
