The invention relates to an optical fiber repeater system using a wavelength division multiplexing technology. The system comprises a near-end machine, a far-end machine and a single-core optical fiber, the near-end machine comprises a near-end wavelength division multiplexing communication subsystem, the far-end machine comprises a far-end wavelength division multiplexing communication subsystem,and the near-end wavelength division multiplexing communication subsystem is connected with the far-end wavelength division multiplexing communication subsystem through the single-core optical fiber.Compared with the prior art, the method has the advantages of high flexibility, low cost and the like.

Description

technical field [0001] The invention relates to the field of photoelectric transmission, in particular to an optical fiber repeater system using wavelength division multiplexing technology. Background technique [0002] In the current analog optical fiber repeater system, the communication connection between the near-end unit and the far-end unit mostly uses single-mode optical fiber. Generally, the working wavelength is 1310nm and 1550nm. It mainly transfers and transmits the monitoring information of radio frequency signals and remote equipment. [0003] If users need to transmit other large-capacity data information, they must occupy the original working wavelength or increase the number of optical fibers, which will inevitably affect the original system or greatly increase the cost. [0004] After retrieval, the Chinese Patent Publication No. CN201563124U discloses a radio frequency optical transmission device, including: a wavelength division multiplexing module that r...
