The 77EYA1 Series 1U High-Power ErYb Doped Fiber Amplifier uses advanced erbium-ytterbium co-doped double-clad fiber technology and high-efficiency low-noise pump lasers. It provides an industry-leading 38dBm (6.5W) total output power and supports 2 to 32 ports with stable output from 13dBm to 23dBm per port.
It features adjustable LCD backlight, complete audible and visual alarms, and a modular design for easy maintenance. It supports WEB & SNMP network management and optional mobile APP remote monitoring. The device supports multiple optional functions: 2-port optical switch (OSW) for optical path protection, built-in optical transmitter, RF signal monitoring, and WDM for triple-play convergence.
It uses a one-button pull-out dual hot-swap power supply with wide voltage input (AC90–264V, optional DC/UPS), ensuring ultra-high reliability for 7×24-hour operation. It is the core equipment for large-scale CATV and FTTH networks.
