TP-Link MC112CS sieťový mediálny konvertor 100 Mbit/s Singlemode čierny

The TP-Link MC112CS is a WDM media converter that converts 100BASE-FX single‑mode fiber to 100BASE‑TX copper Ethernet or vice versa using a single SC connector. Compliant with IEEE 802.3u standards, the unit operates at full wire speed and supports longwave (LX) laser operation: it transmits at 1310 nm and receives at 1550 nm. Using WDM technology, the MC112CS requires only one fiber strand for bidirectional data transfer and supports single‑mode fiber links up to 20 km. The compact standalone device includes status LEDs and requires no chassis.

Advantages

The MC112CS reduces cabling cost by using WDM single‑fiber transmission, provides automatic MDI/MDI‑X and auto‑negotiation on the TX (RJ‑45) port, and delivers IEEE‑compliant 10/100Base‑TX to 100Base‑FX conversion. Its SC fiber connector and support for extended distances (up to 20,000 m) make it suitable for long‑range network links while consuming low power.

Suitable for

• Extending Ethernet over single‑mode fiber links up to 20 km
• Connecting copper Ethernet equipment to fiber backbones
• Point‑to‑point links where single‑fiber WDM cabling is preferred
• Small installations requiring a standalone media converter

How to use

Install the MC112CS near the device to be connected and power it using the supplied adapter. Connect the copper Ethernet device to the RJ‑45 port; the converter will perform auto MDI/MDI‑X and auto‑negotiate speed and duplex on that port. Use a single‑mode fiber cable with SC connectors and ensure the opposite end device is configured for complementary WDM wavelengths (it should transmit at 1550 nm and receive at 1310 nm). Verify link and activity via the front panel LEDs and confirm proper operation on both ends of the fiber link.

Recommendations

Use certified single‑mode SC fiber and verify that the remote media converter or transceiver supports the complementary WDM wavelengths (TX 1550 nm / RX 1310 nm) to ensure correct bidirectional operation. For distances near 20 km, check fiber attenuation and connector quality; consider testing link performance after installation.
