The 077G (77GEYA2) series is a high-performance 2U high-power erbium-ytterbium co-doped fiber amplifier (EDFA) independently developed by Shandong Wanshuo Optoelectronic. Adopting advanced erbium-ytterbium co-doped double-clad fiber technology and high-efficiency low-noise pump lasers, it delivers industry-leading total output power up to 41dBm and supports flexible 16-64 port configurations, making it the ideal solution for large-scale CATV FTTH deployment in medium and large cities.
It features an innovative touch screen design (no physical buttons) with a larger display area and more intuitive operation, plus adjustable backlight time. Equipped with a complete audible and visual alarm system with dual indicator and buzzer alerts, and a modular design for easy maintenance and management. It supports standard WEB network management and SNMP protocol, with optional mobile phone remote monitoring and timing control functions for intelligent operation and maintenance. The device provides multiple optional functions: 2-port optical switch (OSW) for automatic optical path protection, built-in 1550nm direct modulation optical transmitter, RF signal monitoring, and WDM module for triple play convergence of CATV, data and voice services.
Adopting a one-button pull-out dual hot-swappable power supply design with wide voltage input (AC 90-265V, optional DC 36-72V / UPS backup), it ensures carrier-class 99.999% reliability for 7×24-hour uninterrupted operation. It is the core equipment for building high-stability, large-capacity CATV optical transmission networks.
