DWDM Optical MUX / DEMUX
1RU chassis provides optical multiplexing for up to 40 wavelengths in either the L or C band spectrums. An expansion port provides multiplexing of the L and C bands to output a total of 80 channels on a single fiber. Wavelength MUX / DEMUX modules use passive wavelength filters. With no active components, modules offer a very high level of reliability.

DWDM Transmitters and Receivers
Wave division multiplexing allows the use of multiple wavelengths of light on a single fiber, therefore allowing a single fiber to carry multiple signals. Each signal can run at its own bit rate and protocol, independent for the other signals.

Each electrical signal to be multiplexed into the final output must be converted to an optical signal with a unique wavelength by using different lasers on the transmitter. The FST-6602, single electrical to optical transmitter comes in 80 product variants with each card transmitting unique wavelengths. The products are identified by a three digit suffix, which identifies the wavelength's frequency.

Optical to electrical convertors use a wide spectrum optical receiver, and will work with any wavelength. Both the FSR-6601 single and the FDR-6603 dual optical to electrical convertors are wide spectrum receivers and will function within a DWDM system, regardless of the transmitted wavelengths.
