What This Product Does TL-FC311A-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 video surveillance system and wireless networking. How This Product Works TL-FC311A-2 adopts WDM (wavelength division multiplexing) technology, helping send and receive data at a distance of up to 2 km with only one single mode fiber, which saves half of the cable deployment cost for customers compares to dual-fiber deployment. TL-FC311A-2 transmits data at 1550 nm wavelength and receives data at 1310 nm wavelength on optical fiber. Therefore, the terminal device used in conjunction with the TL-FC311A-2 should send data at a wavelength of 1310 nm and receive data at a wavelength of 1550 nm. TP-Link another media converter TL-FC311B-2 is one of the products that can cooperate with TL-FC311A-2. |
