Optical Switching Machine

Optical Switching Machine is one of the frequently used products of quantum key distribution network, and its key function is to realize the TDM of quantum channels.

This series of products include two different types called matrix type and all-pass type.

The matrix type is made of cross fiber links to support signal exchange, which is mostly used in key relay machine with the capability of QKD terminal Seagate expansion and backup.

The all-pass type supports up to 16 channels of optical fiber links, and each channel can be connected to each other. This type of machine shows a good performance in multi-user Metropolitan or Local QKD network.

  1.  Preemptive switch
  2.  Low insertion loss and low crosstalk
  3.  Anomaly detection and log management
  4.  Logic isolation for communication interface
  1.  The interconnection of optical quantum network
  2.  The backup of optical fiber link
  3.  QKD terminal Seagate expansion and backup
