Fully passive Multiplexer(it means it does not require temperature controller and there is no electrical power consumption). With SC/UPC optical adapter interface. Standalone 1RU 19' rack. ITU channel 21-60. See ITU grid definition in the 2nd pdf link below. Optiworks made optical module for Harris systems. The OP+DWDM40 fiber optic module is a 40-channel standalone product in a compact 1RU frame that is capable of dense wavelength division multiplexing (DWDM) and demultiplexing. With its dense signal-to-fiber ratio, the OP+DWDM40 is ideal for long-haul transport of fiber optic signals. Use it to multiplex and transport a large number of signals of various formats — all over a single fiber.

Features • 40-channel passive multiplexer and demultiplexer capability in a 1RU frame

• Compliance with ITU-T G.694.1 standards for DWDM wavelengths

• Multiplexer and demultiplexer capability in one frame

• Bidirectional capability
