Performance Characteristics

Adopt Er-Yb co-doped double-clad fiber technology and low-noise pump laser.

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 2U supports a maximum total output of 41dBm 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.
