Description
Extend Your Network Over Fibre with Confidence
The TP-Link Omada MC211CS-20 is a Gigabit Ethernet to single-mode fibre media converter designed for businesses and installers who need to bridge copper and fibre networks reliably over distances up to 20 kilometres. Whether you're connecting buildings on a campus, linking remote offices, or extending your network backbone, the MC211CS-20 delivers stable, high-speed connectivity without compromise.
Product Description
The MC211CS-20 converts a standard RJ45 Gigabit Ethernet connection to a single-mode fibre SC connector, enabling long-distance data transmission at full Gigabit speeds. It operates on a single fibre strand using WDM (Wavelength Division Multiplexing) technology — transmitting at 1310nm and receiving at 1550nm — making it a cost-effective solution for fibre infrastructure where dual-strand runs aren't available or practical.
The unit is plug-and-play with no software configuration required, making it straightforward for both professional installers and IT staff to deploy. It is also compatible with the Omada MC220L (the complementary converter for the other end of the link), and can be rack-mounted using the optional MC100CM chassis.
Key Features

- Full-duplex Gigabit speeds (1000Mbps)
- Auto-negotiation on the RJ45 port (10/100/1000Mbps)
- Link fault pass-through (LFP) for end-to-end fault detection
- Plug-and-play — no software or configuration required
- LED indicators for power, fibre link, and Ethernet link status
- Compatible with MC100CM rack-mount chassis (up to 16 units)
- Compact desktop form factor with external power adapter
Use Cases
-
Campus and multi-building networks: Connect separate buildings over existing single-mode fibre runs without laying additional cable.
-
ISP and carrier last-mile deployments: Extend fibre to the premises where copper handoff is required.
-
Industrial and warehouse environments: Use fibre to eliminate EMI interference across large facilities.
-
CCTV and IP surveillance backbones: Provide a stable, long-distance uplink for NVR or switch infrastructure over fibre.
-
Data centre interconnects: Bridge fibre backbone segments to copper-based server or switch ports.

Frequently Asked Questions
- What fibre cable does the MC211CS-20 require?
- It requires single-mode fibre (9/125µm) with SC connectors. It uses a single fibre strand via WDM technology, so you only need one fibre run between the two converters.
- What converter do I need at the other end of the fibre link?
- You need the TP-Link Omada MC220L, which is the complementary unit with reversed wavelengths (Tx: 1550nm / Rx: 1310nm). The MC211CS-20 and MC220L are designed to work as a matched pair.
- Can I rack-mount the MC211CS-20?
- Yes. The MC211CS-20 is compatible with the TP-Link MC100CM rack-mount chassis, which holds up to 16 media converters in a standard 19-inch rack bay.
- Does it require any software configuration?
- No. The MC211CS-20 is fully plug-and-play. Simply connect the fibre and Ethernet cables, power it on, and it will operate automatically. No drivers or management software are needed.
- What is Link Fault Pass-Through (LFP)?
- LFP is a feature that propagates a link failure from one port to the other. If the fibre link goes down, the Ethernet port will also drop its link — alerting connected switches or devices to the fault immediately rather than silently failing.
- Is the MC211CS-20 suitable for outdoor use?
- The unit itself is rated for indoor use (0°C to 40°C). For outdoor deployments, it should be housed in a weatherproof enclosure. The fibre run itself can be outdoor-rated single-mode cable.
- What is the maximum distance this converter supports?
- The MC211CS-20 supports fibre runs up to 20km over single-mode fibre — making it suitable for campus, inter-building, and metropolitan area network (MAN) links.
