Test equipment and test method for optical fiber network unit

Abstract

The invention discloses test equipment and a test method for an optical fiber network unit. The test equipment of the optical fiber network unit is used for detecting the optical communication quality of the optical fiber network unit, and comprises an optical transceiving module and a control unit; the sending wavelength and the receiving wavelength of the optical transceiving module are lambda 1 and lambda 2 respectively; the control unit is connected with the optical transceiving module which is sued for receiving the electric signal sent from the control unit so as to enable the optical transceiving module to generate a pulse light source with the wavelength being lambda 1, and the pulse light source is used for detecting; and after receiving the pulse light source with the wavelength being lambda 1, the optical fiber network unit outputs a pulse light source with the wavelength being lambda 2.

Description

technical field [0001] The present invention relates to a test device and a test method, and in particular to a self-made test device and a test method for detecting the optical communication quality of an optical network unit (Optical Network Unit, ONU). Background technique [0002] In recent years, the construction of physical networks has gradually moved towards optical fiber communication networks with large transmission capacity and good security. Especially in the case of long-distance and large-scale transmission, the quality of optical fiber communication is far superior to that of traditional cable communication. To realize fiber-to-the-home (FTTH) services, the common passive optical network (Passive Optical Network, PON) is the mainstream technology. Please refer to figure 1 , which shows a system architecture diagram of a traditional passive optical fiber network. An optical line terminal 10 (Optical line terminal, OLT) is set in the central office equipment ...

Problems solved by technology

Therefore, the test of the optical network unit 30 is the focus of the factory quality test, and the test equipment used today is to purchase expensive instruments, such as externally purchased bit error rate testers (biterrorratetester, BERT) to provide accurate pulses However, its disadvantage is that if the instrument itself fails to repair itself, it must be handed over to the original factory for repair, and the self-made rate cannot be improved, etc.
