Optical Cross Connect (OXC) technology has solved some problems of insufficient electric crossover capacity of Optical Transport Network (OTN) system, as well as complex manual fiber connection and inflexible scheduling between Fixed Optical Add/Drop Multiplexer (FOADM)/Reconfigurable Optical Add/Drop Multiplexer (ROADM) boards. This paper studies how to introduce OXC technology into OTN Metropolitan Area Network (MAN) to improve the flexibility of the network and solve some network security problems caused by the over concentration of OXC.

This paper introduces the advantages of OXC technology, and summarizes the architecture of the OTN system in the existing network, as well as the security configuration mode of the bearer service. By establishing various OXC application models, the paper compares and analyzes the flexibility and security of various models.

After testing in the existing network, the paper summarizes various model evaluation indicators, and finds the optimal application scheme.

In this paper, an all-optical MAN construction model based on OXC is innovatively proposed to promote the application and development of OXC technology, strengthen the scheduling capability between computing forces, and form a new infrastructure of computing network integration. It finally provides users with low latency, highly reliable, end-to-end computing connections.
