Ftth Fiber Optical Sc Apc Upc Mini Steel Tube Plc T Coupler Splitter Application: Lan

The single mode standard coupler features low excess loss, high stability and reliability. It is built by asymmetric coupling technique. The operating bandwidth of this normal coupler is expanding to A A 40nm, and the ultra broadband coupler is expanding to A A 80nm. The DWC has the same coupling ratio on both 1310nm and 1550nm communication windows, and with low excess loss and low PDL. DWC are widely used for communication systems, fiber optic cable coupler CATV, and FTTH.
