Fiber coupler, 1550nm, 1x2 port, single window, 50:50 coupling ratio, 900um loose tube.
The fiber coupler is a general fiber device which is widely used in CATV network. The coupling ratio can be chosen according to customer's requirements. 50:50 coupling ratio is a usual split ratio.
If you have no idea about the coupling ratio, you can provide your insertion loss and we can do it.
