The 77EYA3U series is an industry-leading 3U ultra-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 the highest total output power in the series up to 43dBm and supports ultra-high-density port configurations, making it the core equipment for ultra-large-scale CATV FTTH deployment in large cities.
It features adjustable LCD backlight, 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 90-264V, optional UPS backup), it ensures carrier-class 99.999% reliability for 7×24-hour uninterrupted operation. It is the ideal solution for building high-capacity, long-distance CATV optical transmission networks.
