Embodiment three
Specific application process will be combined in the present embodiment, to the optical fiber rate test system that is proposed in embodiment two
Specifically effect is supplemented and described in detail for annexation or module, and referring to Fig. 3, Fig. 3 is that the embodiment of the present invention three provides
A kind of optical fiber rate test system.
Because the present invention is tested fiber-optic transmission rate, fiber-optic transmission rate tested, first had to
Ensure that optical fiber can carry out data transmission, i.e., the physical arrangement of optical fiber is in connection status.Tested in fiber-optic transmission rate
After system starts, the output port of testing fiber and input port are attached by way of optical fiber winding, in this implementation
In example, optical fiber winding employs ring flange, naturally it is also possible to the external physical winding of optical fiber, this hair are realized using other structures
It is bright without limitation.
Referring to Fig. 3, after the physical arrangement that ensure that optical fiber connects normally, it is ensured that optical fiber can normally carry out data
Transmission can just produce transmission rate, i.e., the fiber-optic transmission rate test system should also include optical fiber state detection unit 100, should
Optical fiber state detection unit 100 is attached with control module 1, i.e., only optical fiber state detection unit 100 detect it is to be measured
When optical fiber is in connection status, enabled instruction can be just sent to control module 1, and then control module 1 is started, and generates optical fiber
Data rate control instructs.
The specific operation principle of the optical fiber state detection unit 100 is passed through using the data or information that are obtained ahead of time
Optical fiber to be measured is transmitted, then according to transmission return data either information judge whether with transmission primary data or
Information is consistent, if it is, being judged as that the optical fiber to be measured is in connection status.Wherein, the data that are obtained ahead of time or
The sequence information that information can be randomly generated, can be pre-prepd verification data, and the concrete form present invention is not limited.
Data rate control word is produced after control module 1 starts, and fiber data is generated according to data rate control word
Speed control instructs, and then sends the instruction into packet generation module 2, now, packet generation module 2 normally opens
It is dynamic, instructed according to the fiber data speed control, generate verification data package.
Wherein, the concrete operating principle of packet generation module 2 is as follows：
The fiber data speed control instruction is parsed, obtains the control corresponding with the fiber data speed control instruction
Word processed；
Meet that the data of the data transfer rate response dutycycle of the testing fiber effectively identify according to control word generation；
Generation verification data package is effectively identified according to the data, wherein, each school in the verification data package
Test packet and correspond to a fiber-optic transmission rate.
Because each verification data bag in verification data package correspond to a fiber-optic transmission rate, default transmission speed
Rate scope is 0GB/s to 10GB/s, so the transmission rate of packet is linear change, the data often wrapped are 64bit line
Property data., it is necessary to which through-rate correction verification module 3 is verified to verification data bag, also after verification data package is generated
It is that fiber-optic transmission rate is tested.
At this moment the fiber-optic transmission rate test system also includes optical fiber interface control unit 200, and optical fiber interface control is single
Member 200 is connected with packet generation module 2 and speed correction verification module 3 respectively, passes through the transmitting terminal of optical fiber interface control unit 200
Verification packet is sent；After verification data bag is received, transmitting terminal passes the receiving terminal of optical fiber interface control unit 200
Speed correction verification module 3 is defeated by be verified.Because packet generation module 2 is to generate verification data package, so packet
It may be multiple, then corresponding optical fiber interface control that generation module 2, which is sent to the verification data bag of optical fiber interface control unit 200,
Unit 200 respectively sends the verification data bag after transmission to speed correction verification module 3.Now speed correction verification module 3 is first to school
Test packet to be ranked up, i.e., according to the ascending order of fiber-optic transmission rate, then to each verification data bag therewith
It is transmitted under corresponding fiber-optic transmission rate, receives the data returned after each verification data bag transmission, and to described
The data of return carry out checking and are verified result；
After result is verified, judge module 4 judges whether the result of current verification data bag is correct, such as
Fruit is will then to verify correct control word and be sent to speed correction verification module 3, it is desirable to obtains increasing the transmission rate of optical fiber to be measured
The result afterwards.Now if speed correction verification module 3 obtains the result after the transmission rate for issuing additional optical fiber to be measured, just
Need first to obtain corresponding speed verification bag after increase transmission rate, will now speed correction verification module 3 to increasing testing fiber
Transmission rate verification data bag, repeat said process and verify to obtain the result after increase speed, judge module 4 again
Judgement is re-started, if the result of data check bag is incorrect, it is determined that now reached the maximum of optical fiber transmission
Data bandwidth, fiber-optic transmission rate corresponding to the verification data bag that the last time is verified are defined as the maximum speed of optical fiber transmission
Rate.It can just be judged as being proved to be successful it should be noted that data must be stablized to receive.
It should be noted that the main function of optical fiber interface control unit 200 is that verification data bag is transmitted, and
It is transmitted in transmitting procedure according to corresponding optical fiber speed in verification data bag.Its principle is if in corresponding optical fiber
When speed can not carry the verification data bag, the verification data bag is transmitted and is sent to the verification of speed correction verification module 3
Packet must be impaired, and now, speed correction verification module 3 can parse the verification data bag and obtain check results.
By technical scheme disclosed in the embodiment of the present invention three, in fiber-optic transmission rate test system, confirming to treat
When light-metering fibre is in connection status, the linear parity number of 0GB/s to 10GB/s bandwidth can be produced by packet generation module 2
According to bag, and the verification data bag under these transmission rates is received, data are verified, the maximum for the testing fiber stablized
Transmission rate, the process are tested automatically by fiber-optic transmission rate test system, that is, are needing to change optical fiber transmission
During speed, transmission rate is increased automatically, without being compiled again to system, improves testing efficiency, and then solve
Determine the problem of FPGA compilation times of the prior art are long, testing efficiency is low.
Each embodiment is described by the way of progressive in this specification, what each embodiment stressed be and other
The difference of embodiment, between each embodiment identical similar portion mutually referring to.For device disclosed in embodiment
For, because it is corresponded to the method disclosed in Example, so description is fairly simple, related part is said referring to method part
It is bright.
The foregoing description of the disclosed embodiments, professional and technical personnel in the field are enable to realize or using the present invention.
A variety of modifications to these embodiments will be apparent for those skilled in the art, as defined herein
General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.Therefore, it is of the invention
