Single-window Wideband Fiber Optic Coupler

Single-mode single-window wideband fiber optic couplers are quality components designed to divide or combine optical signal in optical fiber system. These devices are fabricated by using the fused biconical taper (FBT) process and are reliable over wide range of temperature. Its operating wavelength is 1310nm or 1550nm with bandwidth ±20nm.

The range of coupling ration is from 1:99 to 50:50. Many types of packing and configurations can satisfy our customers' requirements. Particularly, for 1 x 2 devices, our company uses unique process on the rest end to ensure that the directivity for each device can be up to more than 60dB and its long-term stability.

This device is widely used in broadband fiber access networks.
