The TP-Link MC112CS is a 10/100Mbps WDM single-mode fiber media converter designed to convert 100BASE-FX fiber connectivity to 10/100BASE-TX copper Ethernet and vice versa. It provides a practical solution for extending Ethernet networks over long-distance single-mode fiber while using a single fiber strand for bidirectional communication.
The MC112CS features one 100M SC/UPC fiber port and one 10/100Mbps RJ45 Ethernet port. Its Wavelength Division Multiplexing (WDM) technology uses different optical wavelengths for transmitting and receiving data, allowing both directions of communication to travel through one single-mode fiber.
The MC112CS operates at 1310nm for transmission and 1550nm for reception. It is designed to work with a complementary WDM converter using the opposite wavelength arrangement, such as the TP-Link MC111CS.
The primary function of the MC112CS media converter is to bridge a fiber-optic Ethernet network and a copper Ethernet network. The SC/UPC fiber port connects to compatible single-mode fiber, while the RJ45 port connects to standard 10/100Mbps Ethernet equipment.
This makes the MC112CS useful when a network needs to be extended beyond the normal copper Ethernet distance. Instead of running long copper Ethernet cabling, the network connection can be transported over single-mode optical fiber and converted back to copper Ethernet at the remote location.
The MC112CS supports IEEE 802.3u 100BASE-FX and 10/100BASE-TX standards. Its fiber interface operates at 100Mbps, while the RJ45 interface supports 10Mbps and 100Mbps Ethernet connections.
The major feature of the TP-Link MC112CS is its WDM technology. Conventional fiber Ethernet links commonly use separate fiber strands for transmit and receive paths. WDM allows the MC112CS to send and receive data over a single fiber strand by using different optical wavelengths.
The MC112CS uses:
This single-fiber architecture can reduce fiber usage and is particularly useful in installations where only one strand of compatible single-mode fiber is available.
The MC112CS is designed to operate with a complementary WDM converter. Because the MC112CS transmits at 1310nm and receives at 1550nm, the remote converter needs to transmit at 1550nm and receive at 1310nm.
The TP-Link MC111CS provides this complementary wavelength arrangement:
| Feature | MC112CS | MC111CS |
|---|---|---|
| WDM TX | 1310nm | 1550nm |
| WDM RX | 1550nm | 1310nm |
| Fiber | Single-Mode | Single-Mode |
| Fiber Connector | SC/UPC | SC/UPC |
| Maximum Distance | Up to 20km | Up to 20km |
Therefore, a typical point-to-point WDM installation can use one MC112CS at one location and one MC111CS at the other location, connected through one compatible single-mode fiber strand.
The MC112CS supports a specified fiber distance of up to 20km when used with compatible single-mode fiber and within the manufacturer’s optical specifications.
This makes it suitable for long-distance Ethernet links between buildings, offices, network rooms, CCTV locations and remote network segments.
The 20km figure represents the manufacturer’s specified maximum transmission distance. Actual link performance depends on fiber quality, connector and splice losses, optical budget, installation quality and environmental conditions.
The MC112CS provides a 100M SC/UPC fiber interface designed for single-mode fiber. The optical connection should be matched with a compatible single-mode fiber and a WDM endpoint using the complementary wavelength configuration.
When installing a WDM link, it is important to match the fiber mode, connector type, wavelength and optical specifications at both ends.
The copper side of the MC112CS provides one 10/100Mbps RJ45 Ethernet port. It supports 10Mbps and 100Mbps Ethernet connections and includes Auto MDI/MDIX functionality.
Auto MDI/MDIX automatically detects the appropriate Ethernet cable configuration, making the converter easier to connect to compatible switches, routers, computers, NVRs and other Ethernet devices.
The MC112CS is a Fast Ethernet media converter, not a Gigabit media converter. It should not be selected for applications that require 1000Mbps Ethernet or Gigabit fiber conversion.
The MC112CS supports automatic negotiation of half-duplex and full-duplex transfer modes for the applicable Ethernet connection. This allows the converter to establish the appropriate operating mode with compatible connected equipment.
TP-Link specifies full wire-speed forwarding within the supported 100Mbps Ethernet specification.
The MC112CS can be deployed as a standalone media converter, so a separate chassis is not required for a basic point-to-point connection.
For installations with multiple media converters, TP-Link also supports compatible units in the MC1400 chassis. This can provide centralized installation and organization for higher-density fiber conversion requirements.
The MC112CS provides front-panel LED indicators for power and link/activity status. These indicators help technicians quickly check whether the unit is powered and whether the fiber or Ethernet connection is active.
The MC112CS is powered using an external power adapter. TP-Link’s current India specification lists a maximum power consumption of approximately 2.41W, while the current V7.30 datasheet lists a maximum of 1.30W for that hardware revision. Because power specifications can vary by hardware revision, the exact version should be checked for procurement or installation documentation.
