WDM coupler
WDM coupler
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.
