The 77MEA series is a high-performance compact ytterbium-erbium 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 stable output power and excellent signal quality in a compact desktop form factor, making it the ideal cost-effective solution for small and medium-scale CATV network deployment.

It features adjustable LCD backlight, complete alarm system with buzzer reminder, and a modular design for easy maintenance and management. It supports output power adjustment within +0.5~-4dBm range, and provides flexible port configurations: 1-8 SC ports or 2-16 LC ports. The device supports multiple optional functions: 2-port optical switch (OSW) for automatic optical path protection, built-in WDM module for triple play convergence, and OR function.

Adopting a one-button pull-out power supply design with wide voltage input (AC 90-264V, optional DC or UPS backup), it ensures reliable operation for 7×24-hour use. With its ultra-compact size and low power consumption, it is suitable for installation in various space-constrained environments such as community equipment rooms, wall-mounted boxes and desktop deployments.
