CWDM stands for Coarse Wavelength Division Multiplexing, a cost-effective optical communication
technology used to transmit multiple data streams simultaneously over a single optical fiber. Unlike
DWDM (Dense Wavelength Division Multiplexing) which uses narrow channel spacing (e.g., 100GHz or 50GHz),
CWDM typically employs wider channel spacing—most commonly 20nm—across the optical spectrum.
It works by assigning distinct, non-overlapping wavelengths to different data signals, combining (multiplexing)
them at the transmission end for joint fiber transmission, and then separating (demultiplexing) them back to
individual signals at the receiving end. CWDM filters, a core component of this technology, selectively pass
or block specific wavelengths to enable this signal management.
High - Precision Wavelength Selection:
High - Precision Wavelength Selection, ensuring the accuracy and efficiency of signal transmission to meet
different optical communication requirements.
Low Insertion Loss:
Low Insertion Loss, reducing the energy loss of the signal during transmission and ensuring the intensity and quality of the signal.
Excellent Channel Isolation:
Excellent Channel Isolation, effectively avoiding signal interference between different channels and improving the stability of communication.
