Product description
TP-Link MC111CS is a network media converter designed to convert signals between LAN cables (RJ45) and fiber optics (SC), supporting IEEE 802.3u standards 100BASE-TX and 100BASE-FX. It uses WDM technology to send and receive data over a single fiber, reducing fiber installation costs by half. It supports a maximum transmission distance of up to 20 kilometers (12.5 miles) on 9/125μm single-mode fiber, operating at 1550nm for transmission and 1310nm for reception, enabling immediate compatibility with other devices supporting opposite wavelengths, such as TP-Link MC112CS. This converter can be used either as a standalone unit or installed directly into the MC1400 equipment rack.
More features
- Supports UTP Cat. 3, 4, 5, and 5e cables up to 100 meters.
- Can be used as a standalone unit or installed in TP-Link MC1400 equipment rack.
- Features LED indicators for PWR, FX Link/Act, and TP Link/Act status.
- Supports both STP and UTP cabling per EIA/TIA-568 standards.
- Consumes only 2.49W power with an external adapter.
Pros and limitations
Pros
- Uses WDM technology to reduce fiber cable costs by half.
- Supports up to 20 km distance on single-mode fiber.
- Works immediately with MC112CS, enabling unlimited network expansion.
- Easy installation using an external adapter, no internal power wiring required.
- Supports UTP Cat. 3-5e cabling up to 100 meters.
Limitations
- Does not support 1Gbps data transmission.
- Requires a paired device with the opposite wavelength (e.g., MC112CS).
- Power is supplied via an external adapter, not directly connected.
Who it is for
Ideal for organizations needing to extend long-distance networks over fiber optics, such as branch offices, factories, or CCTV systems requiring long-range data transmission without installing two fiber cables.
