MMC (Multimode Couplers) or fiber optic splitters, are Multimode FBT (Fused Biconical Splitter) Splitters with a defined split ratio from one input fiber to 2 output fibers. Couplers fabricated from graded-index (GRIN) fiber are available with Ø50 µm or Ø62. 5/125 µm fiber, with low insertion loss and a broad operating wavelength range from 800 to 1600 nm. FBT Multimode couplers are available with 900µm loose tube single-mode fiber or 250µm bare fiber and are terminated or. Fibermart provides 1x2 Filter Type Multimode Fiber Splitter with good price & quality! 100% Tested and Free Shipping!CMX-SM & CMX-MM Splitter Cables are passive fused fiber optic splitter cables used to split optical signal for routing to multiple devices, inputs, or fiber patch panels with LC fiber standard connectors. Not designed for combining optical signals. Can be used as alternate inputs when designing for. SEDI-ATI's hardened multimode couplers are ideal for optical metrology and sensing for aerospace applications, made to resist to vibrations and mechanical shocks.
