Abstract

The invention discloses a management method of a multi-wavelength passive optical network and an optical module. The method includes: the optical module extracts a module management signal and a device management signal from a received signal input by an optical signal interface, wherein the module management The signal carries management information related to the optical module, and the device management signal carries management information related to multi-wavelength passive optical network equipment. The management method and optical module of the multi-wavelength passive optical network disclosed by the invention can solve the problem that the optical module of the multi-wavelength passive optical network in the prior art cannot support the smooth upgrade of existing equipment to the multi-wavelength passive optical network.

Description

technical field [0001] The invention relates to the field of optical access technology, in particular to a management method and an optical module of a multi-wavelength passive optical network. Background technique [0002] In recent years, with the continuous increase in the bandwidth requirements of access network users, the passive optical network (PON, Passive Optical Network) optical access technology is gradually changing from the traditional time division (TDM, Time Division Multiplexing) technology to the wavelength division (WDM, Wavelength Division Multiplexing) technology transition. Multi-wavelength passive optical network, such as wavelength division multiplexing passive optical network (WDM-PON, Wavelength-Division Multiplexing Passive Optical Network), time division wavelength division multiplexing passive optical network (TWDM-PON, Time-and Wavelength-Division Multiplexing Passive Optical Network) can meet higher bandwidth requirements by increasing the loga...
