Overview:
The main function of
the OA (Optical Amplifier) board launched by D Tech Trading is to compensate
the power of the optical signal in the transmission link, which can
simultaneously amplify the optical signal of up to 48 channels (channel
interval of 100GHz) or 96 channels (channel interval of 50GHz) in C-band, with
the features of flat gain, adjustable gain and small noise index, etc.
Meanwhile, the card has built-in OSC optical monitoring channel to support
OSC-based DCN communication, which is an indispensable and important part of
DWDM system and future high-speed system and all-optical network long-distance
transmission.
Application case:
- Suitable for optical
terminal stations (OTM), used as booster amplifier for multiplexed signals
and pre-amplifier for de multiplexed signals
- Suitable for optical relay
stations (OLA) to amplify bi-directional transmission signals and extend
the transmission distance.
