Time-Interleaving Enabled Co-propagation of QKD and Classical Channels over 100-km Fiber with 10-dBm Classical Launch Power. (arXiv:2304.13828v1 [quant-ph])
cs.CR updates on arXiv.org arxiv.org
The commercial success and wide deployment of quantum key distribution (QKD)
technology depend on the integration of QKD links into existing fiber networks
and sharing of the same fibers with classical data traffic. To mitigate the
spontaneous Raman scattering (SpRS) noise from classical data channels, several
strategies have been developed with their pros and cons, e.g., the placement of
QKD in the O-band sacrifices the fiber loss and can rarely reach beyond 80 km;
the attenuation of classical channels sacrifices …
