The 1550nm SM Filter Coupler using advanced micro-optic filter technology, offers very low excess loss, broad operating band and high stability and reliability. These components are extensively used with large-core double-clad fiber, multi-mode fiber, as these fibers cannot use the FBT process to make fused couplers.
