GF-6800-LA20/G150V – C-Band EDFA Line Amplifier Module
The GF-6800-LA20/G150V is a high-performance C-band Erbium-Doped Fiber Amplifier (EDFA) Line Amplifier designed for the GF-6800 DCI DWDM Optical Transmission System.
The module is designed for in-line optical amplification in DWDM transmission networks, compensating for fiber attenuation and passive optical losses between network nodes. It is suitable for Data Center Interconnect (DCI), metro, backbone and long-haul coherent DWDM applications.
The amplifier provides low-noise optical amplification with adjustable gain and supports multiple operating modes, including Automatic Gain Control (AGC), Automatic Power Control (APC) and Automatic Current Control (ACC).
