BiDi / WDM Transceivers
Specialized BiDirectional (BiDi) and Wavelength Division Multiplexing (CWDM/DWDM) transceivers designed to maximize the capacity of existing fiber infrastructure. By transmitting and receiving data on different wavelengths over a single fiber strand (BiDi) or multiplexing multiple channels onto one pair (WDM), these modules allow network operators to double or quadruple their bandwidth without laying new cabling. Ideal for 5G fronthaul, metro access networks, and enterprise campus backbones where fiber availability is limited.
