Description
TP-Link MC100CM Media Converter – 100Mbps RJ45 to Multi-Mode SC Fibre | 2km
Overview
The TP-Link MC100CM is a compact and reliable media converter that bridges 100Mbps copper (RJ45) and multi-mode SC fibre networks over distances of up to 2km. Operating at 1310nm on both transmit and receive, it complies with IEEE 802.3u standards and supports both standalone desktop deployment and rack-mounted operation via TP-Link’s 19" chassis system. With Auto MDI/MDIX on the RJ45 port and Link Fault Passthrough for rapid fault detection, it is a straightforward, cost-effective solution for extending copper Ethernet over existing multi-mode fibre infrastructure in Australian commercial, industrial, and campus environments.
Key Features
-
100Mbps RJ45 to Multi-Mode SC Fibre Conversion – Seamlessly converts between 10/100Base-TX copper Ethernet and 100Base-FX multi-mode fibre.
-
Up to 2km Fibre Range – Extends your network over multi-mode fibre for building-to-building or campus links up to 2 kilometres.
-
1310nm Wavelength – Standard dual-fibre operation (Tx and Rx both at 1310nm); compatible with standard multi-mode SC patch leads and infrastructure.
-
Standalone or Chassis-Mountable – Operates as a standalone desktop unit or slots into TP-Link’s 19" media converter chassis for rack-mounted, multi-port deployments.
-
IEEE 802.3u Compliant – Meets 10/100Base-TX and 100Base-FX standards for reliable interoperability.
-
Link Fault Passthrough & Far End Fault – Detects and passes through link failures promptly to minimise downtime.
-
Auto MDI/MDIX on RJ45 Port – Eliminates the need for crossover cables on the copper side.
-
Half/Full-Duplex Support – Full duplex flow control (IEEE 802.3x) and half duplex backpressure on the fibre port.
-
LED Status Indicators – PWR, FDX/Col, Link/Act, and SPD LEDs for quick visual diagnostics.
Use Cases
- Extending copper Ethernet over existing multi-mode fibre infrastructure between buildings or floors
- CCTV and IP camera backhaul over multi-mode fibre runs up to 2km
- Campus and industrial networks requiring interference-free fibre connectivity
- Rack-mounted multi-port fibre conversion deployments using TP-Link chassis
- Cost-effective fibre extension where multi-mode infrastructure is already installed

Frequently Asked Questions
What is the difference between the MC100CM and the MC112CS?
The MC100CM uses multi-mode fibre with a standard dual-fibre SC connection (Tx and Rx both at 1310nm) and supports distances up to 2km. The MC112CS uses single-mode fibre with WDM technology (single fibre strand) and supports distances up to 20km. Choose the MC100CM when you have existing multi-mode fibre infrastructure; choose the MC112CS for longer single-mode fibre runs.
Can the MC100CM be rack-mounted?
Yes. The MC100CM is chassis-mountable and slots into TP-Link’s 19" media converter chassis, allowing multiple converters to be installed in a rack for organised, multi-port fibre conversion deployments. It also operates as a standalone desktop unit without a chassis.
What type of fibre cable does the MC100CM use?
The MC100CM uses multi-mode fibre (OM1 or OM2) with an SC/UPC connector. It requires two fibre strands — one for transmit and one for receive — unlike WDM converters that use a single strand. Ensure your existing fibre infrastructure uses multi-mode cable before purchasing.
Can I use the MC100CM for CCTV or IP camera backhaul?
Yes. The MC100CM is well-suited for extending IP camera and CCTV network connections over existing multi-mode fibre runs, particularly between buildings or across large sites where copper Ethernet distances are insufficient.
What is the maximum copper cable length on the RJ45 side?
The RJ45 port supports standard Ethernet copper cable up to 100 metres using Cat3, Cat4, or Cat5 UTP, or 100Ω STP cabling.
Does the MC100CM require a chassis to operate?
No. The MC100CM operates as a fully standalone desktop unit with its own external power adapter. The chassis is optional and used only when rack-mounting multiple converters together.
Installer Note: The MC100CM requires two fibre strands (one Tx, one Rx) at 1310nm. It is not a WDM single-fibre device. Confirm your fibre patch leads and infrastructure are multi-mode SC/UPC before installation. If you need single-fibre WDM operation or distances beyond 2km, consider the TP-Link MC112CS (single-mode, 20km) instead.
