Abstract

The invention discloses an optical cable for hanging an optical fiber acquisition chain. The optical cable comprises a plurality of sections of optical cables which are connected in sequence, and a plurality of connecting parts arranged on each section of the optical cable, wherein the connecting parts are used for connecting the optical fiber acquisition chain with the optical cable; each connecting part is provided with an optical cable socket; each connecting part is provided with a hollow cavity, and an optical uploading branching device and an optical downloading branching device are accommodated in the cavity; and optical signals are uploaded between the optical fiber acquisition chain and the optical cable through the optical uploading branching device, and optical signals are downloaded through the optical downloading branching device. The optical fiber acquisition chain is hung on the optical cable so that the total loss of a detector array is reduced, a band-pass capability of the system is improved, the modularization of the optical fiber detector array is realized, and the portability of equipment and the practicability of the system are enhanced.

Description

technical field [0001] The invention relates to the technical field of optical fiber communication equipment, in particular to an optical cable connected with an optical fiber acquisition chain and a data acquisition system containing the optical cable. Background technique [0002] At present, the depth of China's energy and mineral supply reserve target layer reaches 3,000 meters, but more than 90% of the key equipment for deep exploration and high-end data processing software rely on imports, so the overall exploration technology is in a state of "following". To this end, it is urgent to develop exploration equipment for deep geological structures of 3,000 meters and below, and improve the independent innovation capability and equipment level of earth science detection instruments. [0003] In addition, for applications such as deep mineral and oil and gas resource exploration, due to the complex terrain environment in mining areas and oil and gas production areas, seismi...
