With a display backlight control function, allowing users to adjust the backlight time as needed.

With a comprehensive audio-visual alarm function, supporting dual alarm through indicator lights and a buzzer.

The entire machine adopts a modular design, making it easy to maintain and manage.

Standard network management interface, supporting both WEB management and SNMP, with a feature-rich WEB interface.

The 1U supports a maximum total output of 6.5W(38dBm) and offers adjustable output power, with an adjustable range of +0.5~-4dBm.

Optional functions include optical switch, optical transmitter, and RF monitoring.

Optional WDM function is available, achieving triple-play integration.

One-click pull-out dual power supply hot backup design.

Optional time management and remote monitoring by mobile phone are available.

Applications

The 77EYAxx series Er-Yb fiber amplifier is a high-power multi-output fiber amplifier with a gain spectrum bandwidth of 1545~1560nm. 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 77EYAxx 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.
