OA (Optical Amplifier Card)

Product 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.
