NOTE:
Gigabit CWDM fiber transceiver modules adopt the CWDM technology that uses wavelength division
multiplexers to multiplex optical signals with different wavelengths for transmission over a single optical
fiber, thereby saving optical fiber resources. The receiving end uses a wavelength division demultiplexer
to demultiplex the multiplexed optical signals.
