MxN OXC Optical Quantum Switch

Product description

Optical Quantum Switch is an “optical path switching hub” in quantum secure communication/quantum networks. It is mainly used to route single-photon coherent optical quantum channels on demand to different users or relay nodes within optical fibers. Its biggest difference from a classical optical switch is that it tries not to destroy the quantum state (no measurement, no regeneration, and minimal noise introduction).

Optical quantum switch: processes single-photon / ultra-weak quantum signals. It does not measure quantum states and only switches optical paths. Its key metrics include insertion loss, crosstalk, decoherence and fidelity. It targets quantum key distribution (QKD) and quantum networking, with application scenarios covering QKD metropolitan networks, quantum backbones and classified networks.

Technical Parameters

Note：

1. All parameters are tested at room temperature.

2. The above is the adaptive chassis size of LC and FC flange layout, and the chassis mechanism of other flanges shall be confirmed separately.

3. The above is the insertion loss value without power monitoring and with power monitoring, increasing 0.5dB for each channel.

(1) Indicator light: Power indicator. If the light is on, it means the power supply is normal. Run indicates the operation of the device, which flashes once every 1 second of normal operation.

(2) Optical interface: In 1-64 is the input port, and Out 1-64 is the output port.

(2) RJ45 Ethernet interface and RS-232 serial port: communication interface for equipment monitoring data information.

(3) Wiring post: external grounding post.
