TP-Link TL-FC311B-20 Gigabit WDM Media Converter: Overview
The TP-Link TL-FC311B-20 is a gigabit WDM media converter for ISPs, offices and CCTV installers who need to carry an Ethernet link over fiber. It has one gigabit RJ45 port and one SC fiber port, works over a single fiber using WDM, and reaches up to 20 km on single-mode fiber.
This is the B side unit. It pairs with the TL-FC311A-20 (A side) at the other end of the link. The two units use different wavelengths to send and receive, which is what lets one fiber core carry traffic in both directions.
Fiber links are a reliable way to go beyond the 100 m reach of copper Ethernet, and they avoid the surge and interference problems that long outdoor copper cables often bring in the monsoon.
Key Features
- 1x Gigabit RJ45 + 1x SC fiber: converts a gigabit Ethernet connection to fiber and back.
- Single-fiber WDM (B side): uses one fiber core for both directions, saving cores.
- 20 km single-mode reach: suitable for long links to remote buildings or sites.
- Simple installation: no IP configuration is needed, so it is quick to deploy.
Best For
The customer or remote end of an ISP link, the far side of a building-to-building office connection, remote CCTV points, and any gigabit link that needs to run over one fiber core.
Things to Check Before Buying
- Pair it with a TL-FC311A-20 at the other end. Two B side units will not link.
- Use single-mode fiber with an SC patch cord matching the port.
- Keep the route within 20 km and allow for joint and connector losses.
- Power both ends from a UPS where possible so the link survives load-shedding.
FAQs about TP-Link TL-FC311B-20
Q: What is the difference between the A and B versions?
A: They use opposite transmit and receive wavelengths. One A and one B unit form a working pair over a single fiber.
Q: Does it need configuration?
A: A media converter normally works without IP setup. Connect fiber and Ethernet, power it on and check the link lights.
Q: Can it run on multimode fiber?
A: It is listed for single-mode fiber, so use single-mode.
