Product Details
Low PDL 1x2 1310nm/1490nm/1550nm Three-Window Optical Fiber Coupler
Splitter
1x2 1310nm/1490nm/1550nm Three-Window Optical Fiber Coupler
Splitter Built by asymmetric coupling technique, TWC operating
bandwidth is expanding to 1310nm, 1490nm and 1550nm three
communication windows. The TWC coupler has the same coupling ratio
on 1310, 1490 and 1550nm communication windows, with low excess
loss and low PDL. TWC is widely used for communication systems,
CATV, FTTH, where multiple optical signals pass through single
fiber.
