Product description
The G&H 50 W Optical Fiber Amplifier is a high-power Erbium/Ytterbium co-doped fiber amplifier developed for optical ground stations and advanced free-space optical communication systems.
Designed to amplify modulated optical signals while maintaining stable output performance, the amplifier supports selectable C-band operation and is compatible with DP-QPSK and on-off keying modulation formats.
The system is housed within a 19-inch, 3U rack-mount unit and incorporates the optical amplification architecture, electronic control and monitoring interfaces required for integration into laboratory, ground-station and communications infrastructure.
USB, RS-232 and Ethernet interfaces support integration with external control systems. Water cooling provides the thermal management needed for sustained high-power operation.
