Product Role

The TP-Link MC110CS is a Fast Ethernet media converter that links a 10/100 Mbps copper segment to a single-mode SC fiber run. It suits installers who need to bridge a building-to-building gap or extend a legacy 100 Mbps network beyond the reach of twisted-pair cabling.

Sustained Operation

The unit runs from an external power adapter and is rated for continuous use between 0 °C and 40 °C with humidity up to 90 % non-condensing. Link Fault Passthrough and Far End Fault signalling detect fibre breaks quickly, reducing the time a segment stays down during a cable fault.

Deciding Specification

The converter supports single-mode fibre up to 20 km, so it is the right part only when the fibre path is single-mode and the required distance fits within that limit. It will not operate on multi-mode fibre or exceed the 20 km reach.

Questions about this item

How much power does the TP-Link MC110CS draw when running continuously?

The unit ships with an external switching power adapter and operates within a 0°C to 40°C temperature range, so typical draw is low enough for passive cooling in a ventilated cabinet.

What cabling and patch panels must I already have to use the SC and RJ45 ports?

You need single-mode fibre terminated with SC connectors for the 100M FX port and standard Cat5 or better copper patch leads for the 10/100M RJ45 port, which supports Auto MDI/MDIX.

Will this converter link reliably to a legacy 10 Mbps half-duplex switch on the copper side?

Yes, the RJ45 port complies with IEEE 802.3 and 802.3u, auto-negotiates 10 or 100 Mbps, and supports half-duplex flow control via backpressure for older equipment.
