2

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.

【Methods】

2

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.

【Results】

2

After testing in the existing network

the paper summarizes various model evaluation indicators

and finds the optimal application scheme.

【Conclusion】

2

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.
