OP-FBT-T 1xN Single Mode Triple Window Tree Fused Coupler
   Content
OpticTrans OP-FBT-T-1XN Single Mode Triple Window Optical Coupler uses unique bandwidth expansion technology to change the wavelength characteristics of the device so that in the wavelength 1310nm,1490nm,1550nm three window can meet spectral accuracy requirements at the same time. This device is designed for triple-play of low cost solusion and also be applied to the FTT network, It can realize single fiber with three wavelength of bidirectional transmission.
