Abstract
The invention relates to a cut-over method of a communication optical cable line strip system. The method comprises the following steps of: removing a new optical fiber cladding or a protective covering; cleaning the surface of a naked optical fiber; accessing a new optical fiber after an old optical cable is cut off; measuring the loss of an optical fiber joint; after the optical fiber is accessed, carrying out reinforcing protection on the joint of the accessed optical fiber; and coiling surplus optical fibers to finish processing. Compared with the prior art, in the invention, operations are carried out without interrupting the system on the premise of not interrupting the work of a fiber core system, and the optical cable line is conducted twice during cutting; the time of each fiber conducting is the common fiber conducting time of two machine rooms and is about 2s; and the total interruption time is about 4s, which basically does not influence the communication of users, thereby the circuit utilization rate is effectively improved.
Description
Technical field
The present invention relates to a kind of method for cutting over, especially relate to a kind of cut-over method of communication optical cable line strip system.
Background technology
The optical cable cleft grafting technical management is important, a complicated job.Usually, service operation network requirement 24 hours is uninterrupted, and cutover generally all is that the circuit, the equipment that are using are operated.Unimpeded for guaranteeing the optical cable channel, artificially block in the work of minimizing optical cable cleft grafting and last, the Ministry of Information Industry has issued a series of trunk cable cutover management methods in succession, requires cutover in limited time, and accomplishes rapid, accurate.
Lightguide cable link changes, during cutover, normally in two ends intersection former optical cable is cut off moving, and inserts new cable more respectively.This cutover way can cause circuit interruption, and when adopting a heat sealing machine, break period is generally more than two hours; When adopting two heat sealing machines, break period is also more than 30 minutes.Sometimes because of the heat sealing machine obstacle, can not recover main after optical cable cuts off for a long time and use circuit, this class phenomenon is of common occurrence, can cause heavy losses for the one-level optical cable backbone.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of user communication that do not influence for the defective that overcomes above-mentioned prior art existence, improves the cut-over method of communication optical cable line strip system of percentage of circuit utilization.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of cut-over method of communication optical cable line strip system; it is characterized in that; this method may further comprise the steps: new optical fiber overlayer or outer jacket are removed, cleaned the surface of nuditing fiber again, after old optical cable is cut-off; insert new optical fiber; the measuring optical fiber splicing loss, after optical fiber inserted, the joint to incoming fiber optic carried out the reinforcement protection at last; the fiber reel of surplus wound take out, promptly finish processing.
When described new optical fiber inserts,, list the chromatogram table of comparisons, adopt fusion or mechanical means to finish and be connected with old optical fiber according to new, old optical fiber chromatogram.
Described opticalfiber splicing loss utilizes optical time domain reflectometer to detect in optical fiber end office (EO).
Described reinforcement protection comprises the wrapping fibre-optical splice, optical fiber is leaned on wall or bolt number plate.
Compared with prior art, the present invention is under the prerequisite of not interrupting normal fibre core system works, interrupt system is not operated, lightguide cable link is guided fiber 2 times when cutover, each used time is two common leading the fine time of machine room, is approximately about 2s, and the time of Zhong Duaning is about 4s altogether, substantially do not influence user's communication, effectively improved percentage of circuit utilization.
Description of drawings
Fig. 1 is the process flow diagram of this method.
Embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
Embodiment
A kind of cut-over method of communication optical cable line strip system, the process flow diagram of this method be as shown in Figure 1:
The preliminary work of fibre junction: reconnoitre the working-yard according to design, determine the particular location of optical cable cleft grafting, be familiar with surrounding environment, hold the preceding meeting of worker again, formulate concrete cutover scheme, implement corresponding construction, unit of fit, determine schedule and concrete cutover time, examine the operating position and the optical fiber operating position of photosystem on the optical cable, be ready at last construct needed facility instrument, material and vehicle, unit of fit are determined schedule and concrete cutover time;
The removal of optical fiber coating or outer jacket: the schedule and the time of formulating according to club before the worker enter the working-yard, the contact of communication each point, assign the cutover instruction, on the optical fiber accessory frame (ODF frame) of two ends transmission room, check all systems of cutover optical cable, remove the coat or the outer jacket of optical fiber again;
The cleaning optical fiber surface: after the coat of optical fiber or outer jacket removed, the optical fiber surface that cleaning is exposed;
The preparation of fiber end face: utilize chromatograph to write down chromatogram new, old optical fiber;
Optical fiber in and wiring: in last people's well, disconnect old optical cable, with artificial new optical cable is drawn to well, behind the remaining in accordance with regulations optical cable, cut-off and remove all the other optical cables, according to new, old optical cable chromatography, adopt fusion or mechanical means to finish and be connected with old optical fiber;
The measurement of opticalfiber splicing loss: in the time of fibre junction, detect in end office (EO) with optical time domain reflectometer (OTDR instrument), after the index of splicing loss and overall loss all reached requirement, two end office (EO)s were with the optical fiber confirmation that connects;
Judge joint success or failure: when first after the optical fiber with system connects, being checked errorless, can continue in order to continue, that can notify simultaneously that startup connected uses fiber optic again, carries out test working, to reduce break period, after all fibre junction finishes, through global test, check confirm to continue accurate after, promptly notify relevant switching room to carry out test calls;
The reinforcement of fibre-optical splice is safeguarded: through dialing, after confirming that all photosystems all normally move, notify the workmen to close connector box and the in place work of joint in people's well, carry out the reinforcement of fibre-optical splice and safeguard, comprise the wrapping fibre-optical splice, optical fiber is leaned on wall or bolt number plate;
Whether normally coiling surplus optical cable: connector box is in place finishes, confirm the operation of all photosystems, treat that operation is normal after, the fiber reel of surplus wound takes out, promptly finish processing, the workmen can withdraw the working-yard.
