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
