TP-Link FC311B-2 Gigabit WDM Media Converter
- 1 × 10/100/1000Mbps Auto-Negotiation RJ45 port supports Auto-MDI/MDIX
- Auto-negotiation of Half-Duplex/Full-Duplex transfer mode
- Adopts WDM technology, transmitting and receiving data on one single fiber
- Extends fiber distance up to 2 km

TL-FC311B-2 is a gigabit media converter, providing a gigabit RJ-45 port and a gigabit SC fiber port, which can convert between electrical and optical signals. And long-distance data transmission through optical fiber can be applied to commercial scenarios such as remote surveillance camera installation and extending wireless networks. TL-FC311B-2 adopts WDM (wavelength division multiplexing) technology, helping send and receive data at a distance of up to 2 km with only a single mode fiber, which saves half of the cable deployment cost for customers. TL-FC311B-2 transmits data at 1310 nm wavelength and receives data at 1550 nm wavelength on optical fiber. Therefore, the terminal device used in conjunction with the TL-FC311B-2 should send data at a wavelength of 1550 nm and receive data at a wavelength of 1310 nm. TP-Link another media converter TL-FC311A-2 is one of the products that can cooperate with TL-FC311B-2. Besides, this media converter can be used as a standalone device (no rack required) or used with TP-Link's TL-FC1420 rack for auto MDI/MDI-X in TX port in which duplex mode is automatically negotiated.
