The TP-Link MC112CS is a professional-grade media converter engineered to seamlessly transition network traffic between fiber optic and copper cabling. Designed for environments where distance is a critical factor, it converts 100BASE-FX fiber to 10/100Base-TX copper media and vice versa, making it an essential tool for expanding network infrastructure across large campuses or office complexes. At the heart of the MC112CS is WDM (Wavelength Division Multiplexing) technology. Unlike traditional converters that require two fibers for bidirectional communication, the MC112CS transmits and receives data on a single fiber cable. This innovation effectively halves your cabling costs and simplifies deployment without sacrificing performance. Performance is optimized for long-distance reliability, supporting single-mode fiber with SC-Type connectors to extend your network reach up to 20 kilometers (12.5 miles). It operates using a longwave (LX) laser specification, transmitting data at 1310nm and receiving at 1550nm. To ensure a complete link, this device must be paired with a compatible converter—such as the TP-Link MC111CS—that operates at the inverse wavelengths. Build quality is focused on versatility and ease of use. The device features Auto MDI/MDI-X and auto-negotiation of Half-Duplex/Full-Duplex transfer modes on the TX port, ensuring plug-and-play connectivity. For those scaling their hardware, the MC112CS can function as a standalone desktop unit or be integrated into the TP-Link TL-MC1400 chassis for centralized management. Offering a robust solution for network extension, the MC112CS combines IEEE 802.3u standards with a low power footprint of just 2.41W. It is a cost-effective, reliable choice for Sri Lankan businesses looking to overcome the distance limitations of traditional Ethernet cabling.
