1550 nm Single-Mode Double Clad Coupler Fiber
Nufern's single-mode double clad coupler fiber is designed for 1550 nm amplifier modules utilizing higher power multimode pumps. With a core designed to match SMF-28™ and an inner cladding glass-on-glass structure optimized to accept multimode pump energy, this fiber is ideal for the signal leg in high power CATV couplers.
