Abstract
Description
technical field
[0001] The invention relates to a test technology for a passive optical fiber network, in particular to an automatic test method for an optical network unit. Background technique
[0002] The passive optical network (PON) system structure is mainly composed of the optical line terminal (OLT, Optical LineTerminal) of the central office, the optical distribution network (ODN, Optical Distribution Network) including passive optical devices, and the optical network unit / optical network terminal of the user end (ONU / ONT Optical Network Unit / Optical Network Terminal). Compared with active optical access technology, PON eliminates the active equipment between the central office and the user end, which makes maintenance simple, high reliability, low cost, and can save fiber resources, making PON technology the future optical fiber The main solution for to-the-home (FTTH). With the gradual reduction of PON cost and the gradual expansion of application scale, the t...
