To further illustrate the technical scheme of the present invention below with reference to the accompanying drawings and specific embodiments.
On the one hand, the present embodiment provides a kind of communication networks, successively include A website, B website, C website ... J website
With K website, passes through electric power optical cable between adjacent two website and be connected to.Can in this present embodiment, A website is starting point website, the station B
Point, C website ... J website etc. are intermediate stations, and K website is terminus point.It is understood that the quantity of intermediate stations can
To be zero, one, two, three, four or any number of.Preferably, the fibre core quantity of the electric power optical cable is multiple
Number.
On the other hand, the present embodiment provides a kind of jumping fiber test method, it is suitable for carrying out jumping fiber test to communication network,
The following steps are included:
S10: loopback wiring: referring to Fig. 1, it is one that the fibre core in the electric power optical cable 2 between adjacent two website, which is pressed every two,
Group is divided into several fibre core groups 201, and makes the two fibre cores conducting for the same fibre core group 201 being located in same website；All electric power light
201 quantity of fibre core group of cable 2 is identical.
Preferably, electric power optical cable is 24 cored structures, if all fibre cores are vacant fibre core, every section of electric power optical cable
To form 12 groups of fibre core groups.Generally, jumping fiber is carried out using vacant fibre core.
Referring to FIG. 1 to FIG. 2, optical fiber distributing unit 1 is equipped in each website, specifically, starting point website and terminus point
Configure an optical fiber distributing unit 1；Intermediate stations configure two optical fiber distributing units 2, and one is used for and a upper website
Connection, another with next website for connecting.In step slo, first make between two optical fiber distributing units 1 being connected
Electric power optical cable 2 constitutes loopback circuit.
Preferably, because each fibre core group of the one end for needing that AB electric power optical cable is used to be located at A website in step s 40 as
The incoming end of detection device, so the AB electric power optical cable position of connection A website and B website can be not connected to when carrying out step S10
Each fibre core group in one end of A website.
Preferably, automatic switching-on device can be set, when a failure occurs, the automatic closing that each optical fiber distributing unit is equipped with
Device automatic closing is to realize the loopback wiring between adjacent two website.Certainly, because jumping fiber mainly uses vacant fibre core,
Vacant fibre core can be made to be initially in wrapped state, when needing to test, it is only necessary to which two batches staff, a batch directly exist
Inception point point is tested, and another batch of each website for successively arriving downstream carries out broken string docking.
S20: broken string docking: disconnect A website and B website AB electric power optical cable be located at B website one end each fibre core
Group, disconnect B website and C website BC electric power optical cable be located at B website one end each fibre core group；The AB that every group is disconnected
The fibre core group for the BC electric power optical cable that the fibre core group of electric power optical cable is disconnected with one group is docked, the two fibre core groups docked composition to
Survey time road.
Specifically, AB electric power optical cable and BC electric power optical cable are docked, can be obtained by 12 groups in A website and waits for the survey time
Road, the length in each group of circuit to be measured are twice of AC electric power optical cable length.
S30: loss test: carrying out loss test to each group of circuit to be measured in A website, and the 1/ of loss test institute value
2 be the fibre core loss value between A website and C website；If fibre core loss value is unsatisfactory for requiring, replace AB electric power optical cable and/or
BC electric power optical cable；If fibre core loss value is met the requirements, broken string docking and loss test successively are carried out to next stop point.
Specifically, successively 12 groups of circuits to be measured are detected in A website, it, can if fibre core loss value is unsatisfactory for requiring
To find at once, without that could be found to C website, to reduce the time for returning to maintenance.
Preferably, described that loss test carried out to each group of circuit to be measured in A website, the 1/2 of loss test institute value
Fibre core loss value as between A website and C website, specifically:
Loss test is carried out to each group of circuit to be measured using light source device and optical power device in A website, detects resulting function
The 1/2 of rate loss value is the fibre core loss value between A website and C website.
In the present embodiment, if fibre core loss value is met the requirements, broken string docking successively is carried out to next stop point and loss is surveyed
Examination, specific as follows:
It is understood that C website is terminus point, referring to fig. 2, the S30 if intermediate stations only have B website one
Include:
If fibre core loss value is met the requirements, S40 is executed.
If intermediate stations have B website and C website two, D website is terminus point, referring to Fig. 3, each optical fiber distributing unit 1
It is attached by electric power optical cable 2, the S30 includes:
If fibre core loss value is met the requirements:
To C website execute broken string docking: the BC electric power optical cable for disconnecting B website and C website is located at one end of C website
Each fibre core group, disconnect C website and D website CD electric power optical cable be located at C website one end each fibre core group；Every group is broken
The fibre core group for the CD electric power optical cable that the fibre core group for the BC electric power optical cable opened is disconnected with one group is docked, the two fibre core groups docked
Form circuit to be measured；
Loss test is executed to C website: loss test, loss test gained being carried out to each group of circuit to be measured in A website
The 1/2 of numerical value is the fibre core loss value between A website and D website；If fibre core loss value is unsatisfactory for requiring, CD electric power light is replaced
Cable；If fibre core loss value is met the requirements, S40 is executed.
So analogize, when the quantity of intermediate stations is gradually increased, broken string docking and loss successively are carried out to next stop point
Test then executes S40 until the fibre core loss value that the intermediate stations connecting with terminus point are surveyed is met the requirements.
S40: disconnected end loopback: disconnect J website and K website JK electric power optical cable be located at K website one end it is each
Fibre core group.
It is understood that K website is terminus point.
S50: in A website and K website access device, communication is realized.
It is understood that K website is terminus point.
Jumping fiber test method provided in this embodiment first carries out pairs of loopback wiring to the fibre core of all website two sides, so
Cooperated afterwards using a group of people in starting point and tested, another a group of people successively carries out tearing fine docking open in each node, can make full use of limited
