The Wavelength Division Multiplexing Terminal of Quantum Channels and Classical Channels is designed for QKD+WDM transmission taking advantages of classical links and networks already been built. This product uses WDM technique to combine and transmit classical signals and quantum signals together in one single fiber, and de-multiplex them into separate path at the destination.
This product can avoid the problem of separate fiber links needed to be building in the construction of QKD network, and makes QKD a cost-effective long-term solution.
Compact structure: Modular design, Standard 19-inch rackable enclosure, 1U
Wide applicability: Applied to Metropolitan Area Network, MSTP and optical direct connection network
High isolation degree: Isolation degree of quantum channel to classical optical channel ≥60dB
Small insertion loss: Insertion loss of quantum channel ≤2.0dB, classic channel ≤2.5dB
Classic light intensity can be adjusted: With adjustable attenuation function, classic light power of access equipment can be adjusted
Easy maintained facility: Passive component development, high reliability, easy to maintain
Traditional communication networks such as OTN, IP RAN, SDH, etc
Traditional communication networks such as MSTP and directly connected networks
