The 77F-EA1500 series is a high-performance 1U low-noise erbium-doped fiber amplifier (EDFA) independently developed by Shandong Wanshuo Optoelectronic. Adopting imported high-performance erbium-doped optical fibers from Corning of the United States and internationally renowned brand low-noise pump lasers, it delivers industry-leading low noise figure and high energy conversion efficiency, making it the ideal choice for CATV front-end, trunk relay and node signal amplification.
Equipped with a 32-bit ARM Cortex-M4 core N32G455 processor, it achieves ±0.1dBm ultra-high precision optical power control. It supports a wide input optical power range of -10~+10dBm and provides flexible 1/2/4/8 port configurations with output power up to 26dBm per port. The device adopts a unique dual-module reserved structure, which can be expanded with additional functional modules such as optical transmitters, EDFAs, optical switches and optical receivers, realizing multi-purpose use of one device.
It features a 240*240 TFT color display screen for real-time on-site parameter monitoring, and supports standard SNMP network management protocol for remote monitoring and control. The whole machine adopts high-efficiency switching chips, with an overall power consumption of only ≤20W, which is 50% more energy-efficient than similar products. The one-button pull-out dual hot-swappable power supply (AC 90-264V / DC 36-72V optional) ensures 7×24-hour uninterrupted reliable operation.
