Product Review:

The main function of OTA (Optical Terminal Amplifier) launched by D Tech Trading is to compensate the power of the optical signal in the transmission link, and it can simultaneously amplify the optical signals of up to 48 channels in C-band (100GHz channel spacing) or 96 channels (50GHz channel spacing), with the features of flat gain, adjustable gain, small noise index, and so on. Meanwhile, the board has built-in OSC optical monitoring channel and supports DCN communication based on OSC, which is an indispensable part of DWDM system and future high-speed system and all-optical network for long-distance transmission.

Application Case:

Suitable for Optical Terminal Stations (OTM), to amplify the power of the mux signal and pre-amplify the mux signal
