1310/1550 nm Singlemode Broadband Tree Coupler Module (SBTC)

It offers very low insertion loss and low polarization dependence.
  • Product Detail

The Singlemode Broadband Tree Couplers offer very low insertion loss, low polarization dependence, well controlled uniformity in a wide wavelength range as excellent enviromental stability. These modules have been extensively used to split and mix optical signals in CATV, LANs and other kinds of optical communication systems.
