Technical Advantages
Our CWDM multiplexer/demultiplexer implements thin-film filter technology to deliver:
* 100GHz channel spacing compliant with ITU-T G.694.2
* ≤3dB PDL (Polarization Dependent Loss)
* 30dB adjacent channel isolation
* Compact LGX box packaging with SC/LC connector options
Application Scenarios
✔ 5G Mobile Fronthaul: Aggregates CPRI/eCPRI streams
✔ Metro Edge Networks: Cost-effective wavelength expansion
✔ Data Center Interconnect: 4λ capacity over single fiber pair
✔ Fiber-to-the-Home: Enables multi-service delivery
CWDM technology uses ITU standard 20nm spacing between the wavelengths, from 1270nm to 1610nm. Our CWDM module has 2 to 18 channels. The central wavelength of each channel is specified to one of the ITU-T grid wavelengths. The CWDM module features wide channel bandwidth (13nm). Its isolation is greater than 30dB for adjacent channels, and greater than 40dB for non-adjacent channels. The module also has high thermal stability to ensure reliable performance under different environment.
