Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] The present invention mainly proposes a PON device capable of displaying online status and logical link identification. As mentioned above, the PON system is mainly a topology in the form of P2MP. In the PON system, LLID is used in the data packet transmission process in conjunction with the accompanying drawings. The role played by the OLT, and a brief description of how the ONU obtains the LLID assigned by the OLT through the Multi-Point Control Protocol (MPCP).

[0024] First, pass the figure 2 Let’s illustrate the data packet transmission process in the PON system. In this figure, one central office equipment OLT201, one optical splitter 203, four client equipment ONU205 and four users 208 together form a typical PON system , where the user 208 represents devices connected to the ONU, such as computers, handheld personal ...

Abstract

The invention discloses passive optical network equipment that can display online state and logical link identifier, and aims at solving the problem that the equipment in the prior passive optical network system fails to display the online state and the logical link identifier. According to the characteristics of the multi-point control protocol and the logical link identifier, the invention combines a programmable logic device and a display unit to display the passive optical network equipment of the on-line state and the logical link identifier, thus leading the passive optical network equipment to achieve the efficacy of displaying the online state and the logical link identifier.

Description

technical field [0001] The present invention relates to a passive optical network (Passive Optical Network, PON) device, in particular to a passive optical network device capable of displaying online status and logical link identifiers (Logical Link Identifiers, LLID). Background technique [0002] With the rapid growth of the global Internet, traditional networks have been unable to meet the needs of high-speed information transmission applications. The maturity of optoelectronic industry technology and the diversification of product applications timely provide a large amount of bandwidth for the rapidly growing global Internet. Compared with the traditional cable transmission method, optical fiber transmission has the characteristics of large capacity, small loss, and strong anti-electromagnetic interference ability. Main broadband network (FTTx) technology emerges in competition. FTTx technology is mainly used for fiber optic access network, ranging from regional teleco...
