Optical couplers (or splitters) are used when an optical signal is to be divided to several ports. Splitters are used in 1310 and 1550nm wavelengths. If other wavelengths are to be used, please advise us when ordering. Splitters are available for 2 to 64 ports and they are also available in 19” form factor. They are available with or without connectors. Standalone splitters are equipped with 1m long, 3mm thick cords.
