Problems solved by technology

[0005] (1), the conventional GPON ONU and the router are powered separately, and two power supplies need to be configured, which is not energy-saving
[0006] (2), the conventional GPON ONU is connected to the router through a network cable, and an additional network cable is required
[0007] (3) Conventional GPON ONUs generally have 4 Ethernet ports, but this application requires only one Ethernet port, so conventional GPON ONUs have the disadvantages of large volume, serious waste of hardware resources, power consumption, and high cost

Embodiment Construction

[0026] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific embodiments.

[0027] figure 1 A schematic diagram of the configuration structure of the existing traditional LAN switching system is given. In this article, the downlink direction refers to the direction of downloading service data from the ISP network of the Internet service provider to the user terminal equipment; the uplink direction refers to the direction of uploading service data from the user terminal equipment to the ISP network. In the downlink direction, the network services provided by the Internet service provider ISP are sent to the 1:n passive optical splitter through the local OLT broadcast and then sent to the conventional GPON ONU, and the GPON ONU transmits the received network services through the pluggable WAN The port forwards to the router, and the router then provides it to the end user through the L...

Abstract

The invention provides a local area network switch system and a pluggable gigabit passive optical network optical network unit GPON ONU for the local area network switch system. The pluggable GPON ONU comprises a bidirectional optical transceiver, an ONU chip, a WAN (Wide Area Network) interface processing module, a power processing module, a management interface module and a WAN interface connector. The pluggable GPON ONU can be directly inserted into a WAN interface of a router, so that a network cable is saved, and the router can provide uplink and downlink of the GPON; meanwhile, the pluggable GPON ONU and the router share a power supply, so that the size and the power consumption are relatively small, and convenience and energy conservation are realized.

Description

technical field [0001] The invention belongs to the technical field of optical communication, relates to a design based on a gigabit passive optical network switching system, in particular to a pluggable gigabit passive optical network optical network unit GPON ONU used in a local area network switching system. Background technique [0002] With the increasing bandwidth needs of users, network operators have laid a large number of optical fibers and optical transmission equipment, and through the application of Dense Wavelength Division (DWDM) technology, the bandwidth of the backbone network has made a breakthrough. Gradually develop in the direction of 10G, 40G or even 100G. However, in the section connecting the backbone network with the local area network and the home network, that is, the "first mile", the increase in bandwidth capacity is far from being able to catch up with the increase in the bandwidth capacity of the backbone network, and there is a huge bottleneck....
