WDM coupler

Feb. 1, 1997

The Laser Cascade module allows several transmitters and receivers to be coupled to one optical fiber. The device combines several bidirectional components, allowing use in multiple-wavelength systems. Sources including lasers and LEDs can be coupled as well as photodiodes and avalanche photodetectors. Because the construction is polarization independent, users do not need polarization-maintaining multifiber couplers. Both single-mode and multimode fiber versions are available.
