Fiber-optic couplers

Fiber-optic couplers

The 1 ¥ 2 and 2 ¥ 2 couplers operate at either 1310 or 1550 nm with low excess loss. The couplers are used for combining and separating light at discrete coupling ratios. Operating wavelengths can be up to 20 nm apart. The devices are available with seven specific coupling ratios ranging from 50:50 to 1:99. They provide low insertion loss and high directivity and are environmentally stable and reliable.
