Open Transport Network (OTN) is a flexible private communication network based on fiber optic technology, manufactured by OTN Systems. It is a networking technology used in vast, private networks with a great diversity of communication requirements, such as subway systems, pipelines, the mining industry, tunnels and the like (ref). It permits all kinds of applications such as video images, different forms of speech and data traffic, information for process management and the like to be sent flawlessly and transparent over a practically unlimited distance. The system is a mix of Transmission and Access NE, communicating over an optical fiber. The communication protocols include serial protocols (e.g. RS232) as well as telephony (POTS/ISDN), audio, Ethernet, video and video-over-IP (via M-JPEG, MPEG2/4, H.264 or DVB) (ref).
A dense integrated quantum co-fiber transmitting and receiving device, method and transmission system
This invention discloses a closed-loop quantum co-fiber transmitting and receiving device, method, and transmission system, relating to the field of optical communication technology. The closed-loop quantum co-fiber transmitting device includes a quantum signal multiplexing unit and N-1 classical signal multiplexing units. In the N-1 classical signal multiplexing units, the first classical signal multiplexing unit multiplexes any two input classical optical signals of different wavelengths and outputs the result to the next classical signal multiplexing unit, which then multiplexes the signal with another classical optical signal of a different wavelength. This process continues until the last classical signal multiplexing unit multiplexes the signal with the last classical optical signal of a different wavelength, after which the multiplexed classical optical signal is output to the quantum signal multiplexing unit. The quantum signal multiplexing unit then multiplexes the input classical optical signal with the quantum optical signal and outputs the result. This invention enables quantum co-fiber transmission compatible with multi-band optical communication systems (such as OTN systems), meeting practical application requirements.
