77 MEA Ytterbium Erbium Fiber Optic Amplifier

77 MEA ytterbium erbium fiber amplifier is a high power multi-port output fiber amplifier with a gain spectrum bandwidth of 1545~1560nm. It is mainly designed for the application of CATV or 1~8 continuous ribbon channels (ITU wavelength). It provides a flexible and low-cost solution for the large area of FTTH coverage in large and medium-sized cities.

77 MEA can realize the single wavelength transmission of cable TV signal, or the built-in FWDM can realize the single fiber three-wave transmission design, which is an important equipment for the construction of CATV optical fiber transmission network.
