All Optical Networks

- All-optical Network

The all-optical network refers to directly completing all functions of network communication at the optical layer, that is, directly storing, transmitting, exchanging and processing signals in the optical domain, in which the optical nodes replace the electrical nodes of the optical nodes. 

Existing networks with optical nodes, direct optical fiber communication networks based on optical fibers, that is, broadband networks that use light wave technology to complete information transmission and exchange. 

The information transmission, exchange, and amplification in the all-optical network do not require photoelectric and electro-optical conversion, so they are not affected by the slow response of electronic devices in the original network, effectively solving the "electronic bottleneck". 

As far as the transparency of the signal is concerned, the all-optical network is completely transparent to the optical signal, that is, during the transmission of the optical signal, any network node does not process customer information, which realizes the transparent transmission of customer information. 

The transparent transmission of information can make full use of the potential of optical fibers, making the bandwidth of the network almost inexhaustible. If an optical fiber adopts n channels of WDM, each with 10Gb/s digital signal, the transmission capacity of the optical fiber will be n*10Gb/s, and the current semi-transparent network greatly limits the potential of the optical fiber.
