Optical Switching Machine series realize the time division multiplexing of quantum channels, which are important products of quantum secure communication network. This series of products are located in the convergence node of the network, which centrally manage the network channel resources, and reduce the complexity and cost of the quantum communication network.
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 Metropolitan Area Network.
High performance: Mechanical optical switch, low insertion loss, high isolation between channels
Rich interfaces: Support Ethernet, serial port, USB and other communication interfaces
High security: Physical and logical isolation through external communication interface
High reliability of the platform: ATCA carrier-grade architecture, and redundant design with dual power supply, dual fans,etc
Easy maintained facility: Modular design and Real-time Remote Monitoring
Highly integrated: Modular design of optical switch array, stable and reliable production process
The interconnection of optical quantum network
The backup of optical fiber link
QKD terminal Seagate expansion and backup
According to the way of optical switching, it can can be divided into allpass type and matrix type. The all pass optical quantum sub switch realizes the interconnection of all optical ports in pairs, and the matrix optical quantum switch realizes the interconnection of internal and external optical ports
According to the numbers of optical ports,it can be divided into 16 port all pass type (QOS-AT1), 8 port all pass type (QOS-AT2), 4 × 8 matrix type (QOS-MT1) and 2 × 24 matrix type (QOS-MT4). 16 ports all-pass optical switch has 16 external optical ports. 8 ports all-pass optical switch has 8 external optical ports. 4×8 matrix type optical switch has 4 internal optical ports and 8 external optical ports. 2×24 matrix type optical switch has 2 internal optical ports and 24 external optical ports.
