Problems solved by technology

[0010] Existing Ethernet fiber optic transceivers can only forward user data. In this way, the Ethernet fiber optic transceiver cannot know the operating status of the peer Ethernet fiber optic transceiver, which is inconvenient for the use and maintenance of equipment
Due to the high cost of operation and maintenance, a large number of applications of Ethernet fiber optic transceivers in the broadband operating network environment are limited

Embodiment Construction

[0054] The further implementation of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0055] In the construction of a metropolitan area network using Ethernet, an Ethernet fiber optic transceiver needs to be configured on the switching network side and the access network side. The network topology diagram formed after the metropolitan area network uses Ethernet fiber optic transceivers is shown in Figure 3 , the metropolitan area network is composed of switching network 1 and access network 2. Switching network 1 includes a switch 5 for exchanging data frames and a router 4 for routing data frames to the corresponding destination server. The data routed by router 4 The frame is sent to the IP backbone network 3, that is, the data frame is transmitted to the target server on the Internet. When the data frame exchanged by the switch 5 is to be sent to the user of the remote access network 2, the data frame must be sent to t...

Abstract

The Ethernet optical fiber transceiver includes optical port unit, opto-electronic module, electric port unit, switching unit, control monitor unit, isolating transformer and administrative data processing unit. Inserting and replacing / separating administrative data processing for data frames is carried out by the administrative data processing unit, which is connected to optical port unit, switching unit, and control monitor unit for data interactive. Transmitting and managing data are implemented by inserting and replacing / separating administrative data at middle byte part of lead code of each data frame. The invented method makes Ethernet optical fiber transceivers possible to monitor operational aspect of other party.

Description

technical field [0001] The invention relates to an Ethernet optical fiber transceiver and a data sending and receiving method for the Ethernet optical fiber transceiver. Background technique [0002] Ethernet fiber optic transceivers are mainly used for mutual conversion between two different transmission media in the network system. They are applied in the construction of metropolitan area networks using Ethernet, so that the coverage of Ethernet can reach more than 120 kilometers without relay transmission. . The Ethernet fiber optic transceiver is essentially a small computer network device that realizes the conversion between electrical and optical signals of Ethernet. [0003] Fig. 1 is a schematic diagram of a simple client-to-client processing transmission signal through two Ethernet optical fiber transceivers. The data frame sent by the computer user 10 is first transmitted to the first Ethernet in the twisted pair medium in the form of an electrical signal. After ...
