The 077EYAxx series Er-Yb fiber amplifier is a high-power multi-output fiber amplifier with a gain spectrum bandwidth of 1535~1565nm. It is designed for CATV or applications with 18 continuous channel strips (ITU wavelengths). It provides a flexible and low-cost solution for FTTH large-scale coverage in major cities for CATV systems.
The 077EYAxx can achieve single-wavelength transmission of CATV signals or implement single-fiber three-wave transmission design through built-in FWDM. It is an important equipment for building large and medium-sized fiber transmission networks for CATV.
