Wavelength Division Multiplexing is the technology of using two or more wavelengths to carry signals through the same optical fiber. The signals are generated by separate light sources in the same transmitter, combined for transmission and separated optically at the other end before being detected.

The TC4001 Fiber Optic Wavelength Division Multiplexer (WDM) enables 1310nm and 1550nm wave lengths to be transmitted simultaneously on one (single mode) fiber optic cable. The direction of the optical signals can be in the same direction or opposite direction.

Transparent to incoming data, the TC4001 effectively doubles existing cable capacity by multiplexing two separate signals over a single (single mode) fiber.

The TC4001 will distinguish between 1310nm and 1550nm optical signals. Thus, a user needs to connect the TC4001 to a device (transceiver, modem, etc.) with a 1310nm single mode transmitter at one end and a 1550nm Single Mode transmitter at the far end. It is ideal for situations where existing fiber optic cable capacity is limited, because it doubles existing cable capacity.
