Abstract

The invention relates to a multi-level SOA (Service-Oriented Architecture) nonlinear effect inhibition device, belongs to the field of optical communication and particularly relates to a multi-level SOA (Service-Oriented Architecture) nonlinear effect inhibition device which comprises an input coupler, an input filter, an input isolator, a semiconductor amplifier SOA, an output isolator, an output filter and an output coupler which are sequentially arranged along an optical path. By adopting the device, multi-level cascading based on an SOA is achieved, nonlinear influence of an SOA of a former level and an SOA of a later level is relatively well inhibited, therefore, super-long distance transmission is achieved.

Description

Technical field [0001] The invention relates to a multi-stage SOA non-linear effect suppression device, belonging to the field of optical communication, in particular to a multi-stage SOA non-linear effect suppression device. Background technique [0002] As business requirements continue to increase, bandwidth usage has increased significantly, and ultra-high bandwidth Ethernet services 100GE are growing rapidly. At the same time, with multi-user resource sharing, long-distance transmission and multi-point sharing of 100GE high-speed Ethernet are one of the trends of 100GE Ethernet services. [0003] At present, the optical power of the 100GE Ethernet signal transmitted by the CFP or CFP2 module is about 6dBm, and the sensitivity of the 100GE Ethernet signal received by the CFP or CFP2 module is about 0dBm, so the span loss of high-speed Ethernet service transmission can only achieve 6dB, about 20km. . But the current metropolitan area network is usually around 80-120km. Theref...
