The present embodiment mainly tests optical fiber, and basic principle is to utilize to analyze rear orientation light or forward direction in optical fiber
The method of scattering light measures structural caused by the fiber transmission attenuation and various faults of construction that reasons generate such as scattering, absorbing
Loss, when optical fiber certain point is by temperature or stress, the scattering properties of the point will change, therefore be lost by showing
The disturbance information that outer signals are distributed on sensor fibre is detected with the correspondences of fiber lengths.
Actual test method emits in light pulse to optical fiber, and the information of return is then received in OTDR ports to carry out.When
When light pulse is transmitted in optical fiber, the property due to optical fiber in itself, connector, junction, bending or other similar events are understood
And scattering is generated, reflection.The scattering and reflection of a portion are returned in OTDR.The useful information of return is by OTDR's
Detector measures, they are just as the time on different location in optical fiber or curve segment.From transmitting signals to return signal
Time used, then determine speed of the light in glass substance, it is possible to calculate distance.Following formula just illustrates OTDR
Be how measurement distance.
D=(c × t)/2 (IOR)
In this formula, c is the speed of light in a vacuum, and t is to receiving signal (round trip) after signal transmitting
Total time (being exactly the distance of one way after two values multiplication divided by 2).Because light is slower than speed in a vacuum in glass,
In order to which accurately measurement distance, tested optical fiber have to indicate refractive index (IOR).IOR is indicated by optical fiber production quotient.
After optical fiber parameter, the power of Rayleigh scattering can be indicated out, if wavelength it is known that if it and signal
Pulse width it is proportional：Pulse width is longer, and backscattering power is stronger.The power of Rayleigh scattering is also with emitting signal
Wavelength is related, and wavelength is shorter, and then power is stronger.That is it can be produced than 1550nm signal the track generated with 1310nm signals
The rayleigh backscattering of raw track will height.
Fresnel reflection is discrete reflection, it is as caused by indivedual points in whole optical fiber, these points are by making
The factor composition changed into reverse parameter, such as the gap of glass and air.On these aspects, very strong back-scattering light is had
It is reflected back.Therefore, OTDR is exactly to be located by connecting a little using the information of Fresnel reflection, fibre-optic terminus or breakpoint.

It is converted into optical signal to be sent in optical fiber 1105, reflected signal passes through photoelectric conversion module 1104 in optical fiber 1105
Optical signal is converted into analog signal, then analog signal is converted into digital signal through analog-to-digital conversion module 1101 and is sent to data processing

Collection, obtains the current accuracy time and keeps；
The time service clock module 1302 passes through the clock input interface 1305 connected with temporal logic processing module 1301
The network clocking of input calculates the accuracy of network clocking；
The accurate clock 1303 is surveyed by the synchronous ethernet interface 1304 connected with temporal logic processing module 1301
Calculate the deviation of network time, and calibration network time.
Synchronous physical significance refers to：Two or more amounts changed over time, are consistent or one in change procedure
Fixed relativeness.In the communications field, Frequency Synchronization and time synchronization two layers of meaning can generally be included by synchronizing.
Frequency Synchronization is exactly that so-called clock synchronizes, refers to the spy for keeping certain stringent in frequency or phase between signal
Determine relationship, corresponding significant instant occurs with same Mean Speed, to maintain equipment all in communication network with identical
Rate operation.
That transmitted in digital communication network is the PCM (Pulse Code Modulation) obtained after being encoded to information
Discrete pulse.If the clock frequency between two digital local exchange installations it is inconsistent or due to digital bit stream in the transmission because
Interference damage, and phase drift or jitter has been superimposed, losing for symbol will be generated in the buffer storage of digital exchange system
It loses or repeats, cause to occur sliding damage in the bit stream of transmission.
General described " time ", there are two types of meanings：Moment and time interval.The former refers to a certain of time for continuously passing
Moment, the latter refer to that the interval between two moments is grown.
The operation of time synchronization is exactly to come the clock inside adjusting device and moment according to the time received.Time synchronization
Principle of adjustment and control it is similar to the principle of adjustment and control of clock to Frequency Synchronization, it not only regulated and controled the frequency of clock but also regulate and control clock phase,
The phase of clock is represented with numerical value simultaneously, i.e. the moment.Unlike Frequency Synchronization, time synchronization receives discrete time
Information, discontinuous adjusting device clock, and the adjusting control of equipment clock phaselocked loop is periodic.
There are two main functions for time synchronization：Time service and punctual.It is described with popular voice, time service is exactly " to table ".
Table is acted by irregular, by local moment and etalon time Phase synchronization；Punctual is exactly above-mentioned Frequency Synchronization,
Ensure in the gap to table, local moment and etalon time deviation are not too big.
Synchronous ethernet is a kind of technology using ethernet link code stream recovered clock.
Because Ethernet is an asynchronous system, not needing to high precision clock can also work normally, so general ether
Net equipment is not providing high precision clock.But this is not to say that Ethernet cannot provide high precision clock.In fact, in physics
Layer, for Ethernet using being that serial code stream mode is transmitted as SDH, receiving terminal must have clock recovery function, otherwise can not
Communication.In other words, Ethernet inherently has been provided with the ability of transmission clock in fact, only before us without using and
.
From technical standpoint, because the accuracy of physical layer coding ethernet physical layer extraction clock is even more than SDH's.
It is known that the premise that clock is extracted from stream line is that code stream must keep enough clock transition information, in other words
It is exactly that code stream will avoid continuously length 1 or long 0.The way of SDH technologies is to do primary random scrambler, can be substantially reduced in this way
Even 1 connect 0 probability, but this is only reduced, and continuous 1 or 0 still will appear.And the physical layer coding of Ethernet is
4B/5B (FE) and 8B/10B (GE), average every 4 BIT will be inserted into an added bit, and can never occur continuous 4 in this way
A 1 or 40, easily facilitate extraction clock.
Synchronous ethernet network implements fairly simple, and system needs to support a clock module (clock board), unified defeated
Go out a High Definition Systems clock to all ether interface cards；PHY devices uses this high precision clock on ether interface,
Data are sent.In receiving side, the PHY devices of Ethernet interface come out clock recovery, after frequency dividing on give clock board.
Clock board will judge the quality of time signal clock on each interface, select a precision highest, and system clock is synchronous.
In order to correctly select source, while clock information is transmitted, it is necessary to transmit clock quality information (SSM).Traditional SDH is same
Step ether synchronous with SyncE uses the protection of SSM protocol realization clock sources, and the SSM agreements of SDH are defined in G.781 the inside,
The SSM agreements that SyncE synchronizes ether are defined in G.8264 the inside.
Synchronization Status Message (Synchronization Status Message, SSM), in traditional SDH sync caps
The SSM information of STM-N is transmitted by overhead byte S1；The SSM information of E1 is transmitted in E1 in the SA4-8bit of 0 time slot, Ke Yipei
The arbitrary bit transmission in SA4~SA8 is put, is generally defaulted as SA4；Synchronous ether transmits SSM letters by the slow protocol massages of ESMC
Breath.For SSM for indicating the credit rating of timing signal in synchronization timing link, control clock switch avoids the formation of timing loop,
And it can prevent low-grade clocks from synchronizing high-level clock.
Input and output correction of temporal logic processing unit processes associated clock etc..And it is carried out with data processing unit 102
Data exchange.
1303 module of accurate clock provides accuracy very high clock input.Time service clock module 1302 be usually and
The satellite communications such as GPS, the Big Dipper can synchronize correct time signal.
Clock input interface can input tested network clock.
Synchronous ethernet interface connects synchronous ethernet, test or calibration network time.
Temporal logic processing unit is by the acquisition of time service clock and accurate clock 1303, when can obtain current accuracy
Between and keep；Temporal logic processing unit can calculate network clocking by the network clocking inputted with clock input interface
Accuracy；Temporal logic processing unit can test out the deviation of network time, and can calibrate by the interaction with synchronous ethernet
