Aiming at the problems of the existing Optical Transport Network (OTN) dedicated line bearer network, such as poor delay performance, low service opening efficiency, and low network intelligence, the paper proposes the networking strategy of the new generation government enterprise dedicated line bearer network. It gives the application suggestions of 100/200 Gbit/s, packet enhanced OTN, OTN cluster, Reconfigurable Optical Add-Drop Multiplexer (ROADM)/Optical Cross-Connect (OXC) and other new transmission technologies. The relevant results are also applied to the commercial deployment of an operator's government enterprise dedicated line bearer network. The results show that the construction of the new generation government enterprise special line bearer network has significant economic and social benefits. The delay of the operator's network in the key financial direction has reached the leading level in the industry. The opening time of the private line service has been shortened from the previous average of 60 days to 15 days. At the same time, the operator has the ability to automatically open the end-to-end service.
