OLA (Optical Line Amplifier)
Product Overview
The OLA (Optical Line Amplifier) launched by D Tech Trading is used at intermediate optical amplifier stations to periodically compensate for fiber loss and extend transmission distance. It can simultaneously amplify up to 48 channels in the C-band (100GHz spacing) or 96 channels (50GHz spacing), offering flat gain, adjustable gain, and low noise performance.
The board includes a built-in OSC optical monitoring channel and supports DCN communication based on OSC, making it an essential part of DWDM systems, future high-speed transmission systems, and all-optical long-distance networks.
