Abstract

The present invention provides a GPON link amplifier. The GPON link amplifier is arranged in a line between a local side optical line terminal and a client optical network unit, is used to amplify a downlink optical signal and an uplink optical signal which are transmitted in the line, and comprises an optical line local side ONU optical module, an optical line terminal OLT optical module, an uplink burst mode optical detection control module and a data processing unit. The GPON link amplifier provided by the present invention can satisfy the demands of the terminal users in the remote areas greatly, also can save the operation cost for erecting a local side machine room again, thereby reducing the terminal purchase cost and the daily operation cost substantially. The present invention also provides a control method of the GPON link amplifier.

Description

technical field [0001] The invention belongs to the technical design field of telecommunication and communication, and in particular relates to a GPON link amplifier and a control method thereof. Background technique [0002] With the country's strong support for fiber-to-the-home, EPON and GPON equipment have been commercialized on a large scale in China in recent years. Especially with the decline of GPON cost and the increase of user's demand for bandwidth, new services basically adopt the access mode of GPON link. [0003] In the GPON network, data is transmitted in the form of optical signals. The wavelengths of the uplink and downlink optical signals in the optical fiber are different. The uplink uses an optical signal with a wavelength of 1310nm, while the downlink uses an optical signal with a wavelength of 1490nm. In the actual use of operators, because some end users are too far away from the central office, the power of the optical fiber will continue to attenua...
