High-integration density multi-channel array optical fiber amplifier

Abstract

The invention discloses a high-integration density multi-channel array optical fiber amplifier. A light amplification array is composed of N paths of light amplification array units, and each light amplification array unit comprises an input end, a 1*2 1550 nm waveband light splitter, an Erbium fiber amplification unit and an output end which are connected in sequence; an input light detection module comprises a 1*N 1550 nm waveband light coupler and input PD, and the 1550 nm waveband light coupler is connected with the 1550 nm waveband light splitters of the N paths of light amplification array units; an output light adjusting module comprises a 980 nm pumping laser, a 1*2 980 nm waveband light splitter, a 1*N 980 nm waveband light splitter and output PD; the N paths of light amplification array units (N is an even number larger than or equal to 4) share one pumping laser. The volume is small, and the integration density is high; the output light power is adjustable, the pump is turned off when there is no input light, the pump is turned on when there is input light at any path, and the energy consumption is lowered.

Description

Technical field: [0001] The invention belongs to the field of optical transmission, in particular to a highly integrated multi-channel array optical fiber amplifier. Background technique: [0002] With the rapid increase in the number of Internet users, the interface types used in the wide-area interconnection of the core / aggregation routers are all POS (Packet over SONET / SDH) interfaces, and the data switching center needs to split the optical signal of each channel according to a certain ratio (such as 1:1:1:7, 2:8, etc.), and decompose it for data collection, flow control, data cleaning, content analysis, etc. On the one hand, due to the low optical power from the main branch, optical power amplification is required to achieve normal reception of optical signals; The problem of small signal optical power amplification must also be solved in terms of volume, power consumption, and cost caused by the large number of devices. [0003] The information disclosed in this Back...
