Couplers, Splitters & Combiners

NxM (N = 1–8, M = 4–32) Single Mode Broadband Splitter Module

The N×M Fiber Couplers/Splitters are fabricated by cascading 2×2 fused fiber couplers in a star or tree architecture, providing low insertion loss, excellent channel-to-channel uniformity, high optical power handling, and high polarization extinction ratio for polarization-maintaining (PM) versions. The design offers industry-leading performance over an exceptionally wide operating wavelength range from 370 to 2400 nm and a broad operating temperature range of −40 °C to +150 °C. Standard and custom port configurations are available to meet specific application requirements. Please note that optical couplers, when used as combiners, inherently introduce losses. For example, combining two signals with a 50:50 coupler results in approximately 50% optical loss at each input. Our produces a family of fiber combiners with minimal excess loss.
