The TP-Link MC111CS is a high-performance 10/100Mbps WDM media converter designed to bridge the gap between fiber optic and copper Ethernet networks. Utilizing advanced WDM technology, it transmits and receives data over a single strand of single-mode fiber cable, reducing cabling costs significantly. This device supports IEEE 802.3u standards for both 10/100Base-TX copper and 100Base-FX single-mode fiber, featuring an SC/UPC connector with a fiber transmission distance reaching up to 20 kilometers.

Equipped with one 100M SC/UPC fiber port and one 10/100M RJ45 port with Auto MDI/MDIX, the MC111CS provides flexible connectivity options. It supports auto-negotiation and duplex modes (half/full), offering smooth integration into existing networks. The unit includes Link Fault Pass-Through and Far End Fault capabilities to minimize traffic interruption in case of link failure.

Compact and energy-efficient, it requires an external power adapter and provides clear LED indicators for power and link/activity status. The MC111CS is suitable for standalone deployment or can be mounted in TP-Link chassis systems, making it ideal for extending network reach in enterprise or industrial environments.

Key environmental specs include an operating temperature range of 0°C to 40°C and storage temperatures from -40°C to 70°C, ensuring reliable performance under various conditions.
