Převodník médií TP-Link MC111CS 10/100Mbps

The TP-Link MC111CS is a WDM media converter that converts between 100BASE-FX single‑mode fiber and 100BASE‑TX copper Ethernet. Compliant with IEEE 802.3u standards, it uses an SC connector and supports longwave (LX) laser operation at 1550 nm for transmission and 1310 nm for reception, enabling a single‑fiber transmit/receive link and reducing cabling requirements. The unit supports full wire‑speed forwarding for 10/100 Mbps Ethernet and can operate over single‑mode fiber distances up to 20 km. The device includes front panel LEDs for power and link/activity status and can be used as a standalone unit or mounted in TP‑LINK 19" chassis.

Advantages

The MC111CS reduces fiber cabling by using WDM to transmit and receive on one single‑mode fiber, lowering installation cost. It complies with IEEE 802.3u for reliable 10/100Base‑TX and 100Base‑FX interconnection and provides auto MDI/MDI‑X and auto‑negotiation on the TX port for simplified connection to Ethernet devices. Small power consumption and LED indicators allow easy status monitoring.

Suitable for (tasks / use cases)

• Extending Ethernet networks over single‑mode fiber links up to 20 km
• Connecting remote network segments where fiber cabling cost or pathway is limited
• Integrating fiber links with existing 10/100Base‑TX copper equipment
• Standalone media conversion or installation within TP‑LINK 19" chassis

How to use

Install the MC111CS as a standalone unit or insert it into a compatible TP‑LINK 19" chassis. Connect the RJ‑45 TX port to your switch or router; the TX port supports auto MDI/MDI‑X and auto‑negotiation. Use a single‑mode SC fiber cable to connect the fiber port to the remote converter, ensuring the remote device is configured with opposite wavelengths (it should transmit at 1310 nm and receive at 1550 nm). Power the unit and verify link/activity LEDs to confirm successful connection.

Recommendations

Use single‑mode SC fiber with proper termination and follow standard fiber installation practices. Verify wavelength pairing with the remote media converter (MC111CS transmits at 1550 nm and expects the remote end to transmit at 1310 nm). For distances near 20 km confirm link budget and consult TP‑LINK documentation for chassis power options if integrating multiple modules.
