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

⠀⠀⠀⠀⠀⠀⠀⠀⠀

low insertion loss, low polarization dependence, well controlled uniformity in a wide wavelength range

The SBTC 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.
