TP-Link MC111CS Network Media Converter

TP-Link MC111CS | 20 km Single-Mode Media Converter

The TP-Link MC111CS network media converter 100 Mbit/s Single-mode Black is a compact device that bridges 100BASE-FX fiber optic networks with 10/100Base-TX copper Ethernet, making it ideal for extending network infrastructure over long distances without expensive upgrades.

Key Specifications

Extend Networks Up to 20 km Without Infrastructure Overhaul

The MC111CS eliminates the need for costly fiber-to-copper conversion equipment by supporting 20 km single-mode fiber connections. This makes it perfect for connecting remote buildings, campus facilities, or industrial sites where running new copper cabling would be impractical or prohibitively expensive.

WDM Technology Cuts Fiber Costs in Half

Using Wavelength Division Multiplexing (WDM), this converter transmits and receives data over a single fiber strand instead of requiring two separate cables. This innovative approach effectively halves your fiber cabling costs while maintaining full-duplex communication at 100 Mbit/s speeds.

Universal Compatibility with Auto-Negotiation

The device features Auto MDI/MDI-X and auto-negotiation for duplex mode on the copper port, ensuring seamless integration with existing network equipment. Whether connecting to switches, routers, or other media converters, the MC111CS automatically configures itself for optimal performance without manual intervention.

Compact Design for Easy Installation

Measuring just 95 × 73 × 27 mm and weighing minimal, the black chassis fits easily into network racks or can be wall-mounted near existing infrastructure. The front panel LED indicators provide clear status monitoring for power, link, and activity, simplifying troubleshooting.

Frequently Asked Questions

Q: What fiber cable do I need for the MC111CS?

A: You need single-mode fiber cable with SC-Type connectors for this converter to function correctly.

Q: Can I use this with any network switch?

A: Yes, as long as your switch supports 10/100Base-TX Ethernet connections on the copper side.

Q: How does the WDM technology work?

A: WDM allows bidirectional communication over one fiber by using different wavelengths – 1550nm for transmit and 1310nm for receive.

Q: What’s the power requirement?

A: The device consumes a maximum of 2.49W and comes with a standard power adapter.

Q: Can I use multiple MC111CS units together?

A: Yes, but the paired device must use complementary wavelengths – 1310nm transmit and 1550nm receive.
