C&L (C/L) Band 1X2 and 2X2 Fiber Optic Couplers & Optical Splitters

   Gould's C&L (C/L) Band fiber optic couplers & Optical Splitters are ideal for DWDM (Dense Wavelength Division Multiplexing) systems and OTDR (optical time-domain reflectometer) applications, providing excellent performance for applications that operate in the C&L Band from 1530nm to 1625nm. These couplers & Splitters exhibit low optical insertion loss, and low sensitivity to polarization and wavelength. C&L Band couplers are available in a variety of splitting ratios from 50/50 to 99/1 tap versions.
