TL-FC311B-20 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 park security monitoring and wireless networking.
How This Product Works
TL-FC311B-20 adopts WDM (wavelength division multiplexing) technology, helping send and receive data at a distance of up to 20 km with only a single mode fiber, which saves half of the cable deployment cost for customers. TL-FC311B-20 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-20 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-20 is one of the products that can cooperate with TL-FC311B-20.
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.
|Supported Cable Distance (Maximum)||20 km|
What happens after I've placed an order?
Once you place an order with us you'll receive an email confirmation listing all your items ordered. You should keep this email for future reference as it also acts as your invoice. We then start to process your order; the order is transmitted to our paperless production facility, built, checked for quality, handed to our installation engineers who then proceed with setup of any software you've ordered, then run through our burn-in and stability tests, checked once more for quality and finally it's handed to our dispatch department who will pack the order and book it in for delivery. Depending on how busy we are this entire process takes around 3-5 working days.
