Design method for realizing high-speed data bus by optical fiber channel

Abstract

The invention relates to a design method for realizing a high-speed data bus by an optical fiber channel, comprising an Ethernet passive optical network configuration method, a three-layer exchange mechanism, a topology of optical fiber bus design, a bus controller, an access unit, a photoelectric conversion module, a light splitter, and an optical fiber. Before the invention, technologies related to an optical fiber high-speed data transmission bus use foreign standards, and as the technologies and chips for realizing the technologies belong to the scope of embargo of the west to China, China could not directly use the standards. According to the invention, a new method is used to replace a similar foreign technology, and an optical fiber high-speed data transmission bus product standard system of our own is established, so that the optical fiber high-speed data transmission bus technology can be widely applied to spaceflight, aviation, war industry, electronic industry and other fields.

Description

technical field [0001] The invention belongs to the field of electronic information and communication technology, and relates to a design method and principle for realizing a high-speed data bus by using an optical fiber channel. Background technique [0002] 1. Ethernet Passive Optical Network (EPON) [0003] Ethernet passive optical network is a network that uses optical fiber as the transmission medium and Ethernet protocol as the upper layer transmission protocol. It consists of four parts: Optical Line Terminal (OLT), Optical Network Unit (ONU), Passive Optical Splitter (POS), and Optical Line. The optical fiber line terminal OLT completes the data exchange and control between each access ONU; the optical network unit ONU completes the transfer with the user equipment, and the optical splitter completes the branching of the optical path; the optical fiber is the channel for data transmission; the Ethernet passive optical network It is a new type of broadband access te...

Problems solved by technology

A Layer 2 switch can only connect computers with IP addresses in the same subnet. If the IP addresses of computers are in different subnets, even if they are connected to the same switch port, they cannot communicate with each other even though they are close at hand, because now The computers communicate with each other through IP addresses, and the switch does not recognize the IP addresses

[0022] The emergence of VLAN technology is mainly to solve the problem that switches cannot limit broadcasting when interconnecting LANs.
