What This Product Does\n TL-FC311A-2 is a gigabit media converter, providing a gigabit RJ-45 port & a gigabit SC fiber port, which can convert between electrical & optical signals. & long-distance data transmission through optical fiber can be applied to commercial scenarios such as park security monitoring & wireless networking.\n\n How This Product Works\n TL-FC311A-2 adopts WDM (wavelength division multiplexing) technology, helping send & 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-FC311A-2 transmits data at 1550 nm wavelength & 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 & 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.\n\n Other Features\n 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.\n\n\n\n\n\n Product Model: Gigabit WDM Media Converter\n\n\n
