MC112CS | TP-Link 10/100Mbps WDM Media Converter – Single-Mode Fiber up to 20km

The TP-Link MC112CS is a 10/100Mbps WDM (Wavelength Division Multiplexing) Media Converter, engineered for long-distance single-fiber transmission using SC connectors. By leveraging WDM technology, it transmits and receives signals over a single strand of fiber, significantly reducing fiber cable infrastructure costs without compromising performance.

Designed in compliance with IEEE 802.3, 802.3u, and 802.3x standards, this converter extends your fiber network up to 20 kilometers via single-mode fiber, making it ideal for use in ISP backhaul, campus networks, and enterprise edge deployments. Advanced features such as Link Fault Passthrough (LFP) and Far End Fault (FEF) ensure timely detection of link failures, improving network uptime and reliability.

Its plug-and-play design, compact form factor, and fanless operation provide silent, seamless integration into any desktop or wall-mounted environment.
