PLC chip, single-fiber bidirectional optical assembly, optical module and working method

Abstract

The invention discloses a PLC chip, a single-fiber bidirectional optical assembly, an optical module and a working method, and belongs to the technical field of optical communication. The module comprises a transmitting port, a filtering element, a receiving port and a public port, the transmitting port is communicated with the filtering element through an optical transmission channel I; the filtering element is communicated with the receiving port through an optical transmission channel II; the filtering element is communicated with the public port through an optical transmission channel III; an optical switch unit I is arranged on the optical transmission channel I; an optical switch unit II is arranged on the optical transmission channel II; and an optical switch unit III is arranged on the optical transmission channel III. The optical units such as the narrow-band filter, the optical switch and the photoelectric detector are integrated in the PLC, so that the transmitting and receiving wavelengths in the optical assembly can realize a very small interval, and the wavelength resources are more effectively utilized.

Description

technical field [0001] The invention belongs to the technical field of optical communication, and in particular relates to a planar optical waveguide PLC chip, a single-fiber bidirectional optical component, an optical module and a working method. Background technique [0002] In recent years, with the deepening of the deployment of optical communication networks, the number of optical fiber communication equipment sites is increasing. The current optical communication network is mainly connected by dual-fiber bidirectional or single-fiber bidirectional. The dual-fiber bidirectional optical module has the problem of serious consumption of fiber resources. The conventional single-fiber bidirectional optical module consumes less fiber, but due to the large interval between the two working wavelengths, there is a problem that the wavelength in the transition zone cannot be used and the wavelength resource consumption is serious. The existing two optical module connection method...

Problems solved by technology

The dual-fiber bidirectional optical module has the problem of serious consumption of fiber resources. The conventional single-fiber bidirectional optical module consumes less fiber, but due to the large interval between the two working wavelengths, there is a problem that the wavelength in the transition zone cannot be used and the wavelength resource consumption is serious.

The existing two optical module connection methods lead to higher construction and operation costs of optical communication networks
