Wavelength division multiplexers (WDM) are electronic devices that combine light signals with different wavelengths, coming from different fibers, onto a single fiber. They are a cost effective method to expand the capacity of existing fiber optic cables. WDMs use current electronics and fibers and. With the software RP Fiber Power one can simulate how channel powers evolve in a system, how cross-talk arises from nonlinear interactions, etc. Selection criteria, tradeoffs, and 73 suppliers – including: Find more supplier details at the end of the Encyclopedia article.
