Red/Blue filter is an additional passive component for WDM optical networks. It is often used to increase bandwidth and reduce link insertion loss in high-channel count DWDM systems. Actually, it is just like a regular Filter-based WDM (FWDM), with the only difference that the wavelengths are split in Red/Blue filter while bonded in WDM. DWDM Red/Blue C-band Filter is used to separate or combine Red and Blue band wavelength signals in C-band DWDM systems and high-power amplification systems. Powerlink provides custom channel and custom band filters to meet special control and applications.
The product is mainly used to separate or combine Red band wavelength signals and Blue band wavelength signals in C Band, in DWDM systems and high power amplification system . The components are characterized with wide passband, low insertion loss, high return loss, excellent environmental stability and high power handling capability.
