Abstract

The embodiment of the invention discloses an optical fiber transmission system and an optical fiber circulator to solve the problems that an existing optical fiber multiplication scheme is tedious in implementation process and slow in service opening speed. The system comprises first equipment, second equipment and at least two optical fiber circulators, wherein the at least two optical fiber circulators comprise a first optical fiber circulator and a second optical fiber circulator, and each optical fiber circulator comprises at least three ports; when a first device receives an optical signal, the optical signal is transmitted to a first receiving end of a second device from the first device through a first optical fiber circulator, a link fiber core and a second optical fiber circulator in sequence; and when the second equipment receives the optical signal, the optical signal is transmitted to the second receiving end of the first equipment from the second equipment through the second optical fiber circulator, the link fiber core and the first optical fiber circulator in sequence. According to the scheme, at least one link fiber core can be saved for bearing the new service, the purpose of optical fiber multiplication is achieved, the operation of accessing the optical fiber circulator is simple, and the service opening speed is increased.

Description

technical field [0001] The invention relates to the technical field of optical fiber transmission, in particular to an optical fiber transmission system and an optical fiber circulator. Background technique [0002] At present, the wireless 4G (the 4th Generation mobile communication technology, fourth generation mobile communication technology) networking and the 5G (5th generation mobile networks, fifth generation mobile communication system) technology that is currently focused on are gradually moving towards the fiber multiplication network architecture. Evolve and grow to reduce operating costs. This has led to a double increase in the demand for link fiber cores, and it will be difficult to cope with the huge impact of the doubled link fiber core demand brought about by the rapid development of services through the optimization measures of "replacing small-core optical cables with large-core optical cables" in the traditional sense. Exploring fiber multiplication tech...
