A signal transmission method of an optical fiber repeater with transparent transmission function

Abstract

The invention discloses an optical fiber repeater with the unvarnished transmission function and a signal transmission method and belongs to the technical field of communication. The optical fiber repeater with the unvarnished transmission function comprises a near-end machine and a far-end machine, wherein the near-end machine and the far-end machine are connected through optical fibers and are respectively connected with a high-speed unvarnished transmission module. When an uplink signal is transmitted, a GSM signal and the unvarnished transmission signal enter an RFin port of the near-end machine at the same time and are transmitted to the far-end machine after photoelectric conversion is conducted. After the unvarnished transmission signal is isolated and filtered through a far-end machine circuit, the unvarnished transmission signal is received by the unvarnished transmission module through coupling and then transmitted in a wired or wireless mode. The GSM signal enters a power amplifier through an RFout port and is amplified and then wireless coverage is conducted on the GSM signal by a far-end duplexer through an antenna. A downlink signal is transmitted in the reversed direction. The optical fiber repeater with the unvarnished transmission function has the advantages that the high-speed unvarnished transmission module is flexibly, simply and movably connected to a network in a certain range, application of an existing system device is not influenced, data transmission bandwidth is large, the transmission speed is high, returning is convenient when a fault occurs, and the optical fiber repeater is easy and convenient to use and high in efficiency.

Description

technical field [0001] The invention relates to the communication field, in particular to a signal transmission method of an optical fiber repeater with a transparent transmission function. Background technique [0002] With the rapid development of mobile communication, mobile communication users have put forward higher requirements for communication signal quality and data transmission rate. Optical fiber repeater transparent transmission technology to improve signal coverage and data transmission rate came into being. [0003] The traditional data transparent transmission function is embedded in the optical fiber repeater equipment, the hardware uses a separate transparent transmission module, the structure is relatively complicated, and the software requires a separate functional logic, because it must not affect the existing repeater equipment function application and It meets the GSM-R communication protocol, so the system software is relatively large and the logic is ...
