Abstract

Patent of the present invention is related to a kind of optical fiber adaptation transmitter rate fiber hub implementation method, a buffering trough built in the fibre concentrator of this method description, when carrying out signal transmission through fiber, signal is first transferred to the buffering trough of fibre concentrator, the speed that fibre concentrator can be matched further according to descending fiber optical transceiver carries out rate matched, matches the speed after speed further according to matching and carries out the transmission of fiber-optic signal.Simultaneously this method limit the rate-matched of fibre concentrator and fiber optical transceiver be each fiber-optic signal start when and fiber-optic signal run into bursty interference when carry out, during signal transmission through fiber it is without exception then without.

Description

A kind of optical fiber adaptation transmitter rate fiber hub implementation method
Technical field
Patent of the present invention is related to computer optical fiber transmission network field.
Background technology
Fibre concentrator refers to the equipment being connected to a plurality of optical fiber set under same section of physical medium.Fibre concentrator is Operate the physical layer in osi model.It can be regarded as the repeater of multiport, if it detects collision, it can submit obstruction Signal.Fibre concentrator would generally enclose BNC and/or AUI adapters to connect traditional 10base2 or 10base5 network. Fibre concentrator works in the physical layer of OSI/RM reference models and the MAC of data link layer(Medium access control)Sublayer.Thing Reason layer defines electric signal, symbol, the state and clock request of line, the connector of data encoding and data transfer.Because Fibre concentrator is retransmitted again after shaping, amplification are only carried out to signal, without coding, so being the equipment of physical layer.
Fibre concentrator employs CSMA/CD(Carrier frame listens multiple access/collision detection)Agreement, CSMA/CD are MAC layer Agreement, so the fibre concentrator also content containing data link layer.The course of work of fibre concentrator be it is very simple, it Such it can be briefly described:It is that node sig receives the signal to circuit, fibre concentrator first, because signal is in cable biography There is decay in defeated, amplify the signal shaping of decay after fibre concentrator reception signal, last fibre concentrator is by the letter of amplification Number broadcast is transmitted to other all of the ports.
The infrastructure device that fibre concentrator belongs in data communication system, there is traffic monitoring function.It and twisted-pair feeder etc. Transmission medium is the same, is a kind of hardware device for being not required to any software support or only needing seldom management software management.It is extensive It is applied to various occasions.Fibre concentrator works in a network environment, is referred to as physical layer equipment.Used inside fibre concentrator Electrical equipment interconnection, when the environment for safeguarding LAN is logic bus or ring type structure, can establish one with fibre concentrator completely Star-like or tree network structure physically.In this respect, repeater of the fibre concentrator role equivalent to multiport. In fact, fibre concentrator is actually one kind of repeater, and it, which differs only in fibre concentrator, can provide more ends Oral business.Fibre concentrator is to build the most economical implementation of network at present due to own characteristic simultaneously.
Patent of invention content
Patent of the present invention is related to a kind of optical fiber adaptation transmitter rate fiber hub implementation method, the optical fiber collection of this method description A buffering trough built in line device, when carrying out signal transmission through fiber, the buffering that signal is first transferred to fibre concentrator is reserved Area, the speed that fibre concentrator can be matched further according to descending fiber optical transceiver carry out rate matched, match after speed root again The transmission of fiber-optic signal is carried out according to the speed of matching.This method limit the speed of fibre concentrator and fiber optical transceiver simultaneously It is without exception during signal transmission through fiber with being carried out when starting for each fiber-optic signal and when fiber-optic signal runs into bursty interference Then without.
