Description
Overview
GAOTek coarse wave division multiplexing module combine or split up to 18 wavelengths into a single fiber. CWDM technology uses ITU standard 20 nm spacing between the wavelengths, from 1270 nm to 1610 nm. Our CWDM module has 4 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 (13 nm). Its isolation is greater than 30 dB for adjacent channels, and greater than 40 dB for non-adjacent channels. The module also has high thermal stability to ensure reliable performance under different environment.
Features
- Low Insertion Loss
- High Isolation
- Low PDL
- Compact Design
- Good channel-to-channel uniformity
