Overview:
The
main function of OLA (Optical Line Amplifier) launched by D Tech
Trading is used at the intermediate optical amplifier station in the line,
to periodically compensate for the loss of each section of the optical fiber,
and to extend the transmission distance 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.
