Multimode Fibre Splitter
AFW Technologies Multimode 1x2 couplers are bidirectional and can be used as couplers or splitters. The MM graded index couplers offer low insertion loss and excellent environmental and mechanical stability. The multimode couplers are available in 50/125um and 62.5/125um fiber types and operate at 850nm or 1310nm wavelength range.  Multimode Couplers are available with 3mm cable jacket, 900Ám loose tube jacket or 250Ám bare fiber.
