OA (Optical Amplifier Card)

OA (Optical Amplifier) Board – DWDM System

The OA (Optical Amplifier) board from D-Tech Trading is designed to compensate optical signal loss in DWDM transmission systems. It supports amplification of up to 48 channels (100GHz spacing) or 96 channels (50GHz spacing) within the C-band. With features like flat gain, adjustable gain, and low noise, this board is essential for long-distance optical transmission and all-optical network deployment.

Applications

Use Cases
Used in Optical Terminal Stations (OTM) as Booster Amplifier (BA) and Pre-Amplifier (PA)
Used in Optical Line Amplifier (OLA) stations for bi-directional signal amplification
Extends transmission distance in DWDM optical networks
