The OP+DWDM8 is an eight-channel fiber optic module capable of dense wavelength division multiplexing (DWDM) and demultiplexing. With its dense signal-to-fiber ratio, the OP+DWDM8 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.
