Description
Technical field
The utility model relates to a kind of optical fibre fault monitoring system.
Background technology
Due to optical fiber communication have capacity large, transmit that information quality is high, the advantage such as long transmission distance, stable performance, anti-electromagnetic interference, resistance to corrosion are strong, and obtained people's favor.Particularly in nearly ten years, along with people are to the improving constantly of broadband services demand, optical fiber communication has obtained greatly developing.But meanwhile, the maintenance and management problem of optical fiber or optical cable is also outstanding day by day.Along with the increase of number of fibers and lay in early days the aging of optical fiber, the number of stoppages of fibre circuit is in continuous increase.The trouble shoot difficulty of traditional fibre circuit maintenance management pattern, the troubleshooting time is long, affects the normal work of communication network, and the economic loss causing because of communications optical cable fault is every year huge.Therefore, implement the supervising and management in real time to fibre circuit, dynamically observe the deterioration condition of fibre circuit transmission performance, find in time and forecast optical fiber hidden danger, to reduce the incidence of optical fiber blocking-up, the fault of shortening optical fiber is lasted and is seemed most important.
Three historical stages have been experienced in fiber-optic monitoring technical development:
First stage, in the eighties in 20th century, optical fiber is large-scale application just, and owing to being all the new fiber optic network of laying, the probability going wrong is less, and most of fiber failure and hidden danger are all human failure and destruction.Therefore, optic-fiber monitoring system was just advanced a theory at that time, adopted portable OTDR instrument to go the technology detecting or OTDR patrols and examines to carry out fiber-optic monitoring.
Second stage, in late 1980s, to late 1990s, along with the development of optical fiber technology and rapidly application, optical fiber consumption is with annual 30% speed increase.A part of optical fiber of early laying is due to reasons such as deteriorated, human failures, and it is more outstanding that fiber failure starts to become.At this moment, fiber-optic monitoring technology starts maturation, adopts light power meter Real-Time Monitoring and OTDR(Optical Time Domain Reflectometer, optical time domain reflectometer) test mode, has realized the Real-Time Monitoring to optical fiber, optical cable.
Phase III, at the beginning of 20 end of the centurys to 21 century, along with appearance and the development of all-optical network equipment and technology, especially present, worldwide optical fiber communication and photoelectronic industry have entered a new period without doubt, and the all-optical communication network technology based on advanced optical device and light signal treatment technology and equipment will thoroughly change the looks of whole wireline communication network.Adopt the technology such as WDM and DWDM to combine optical fiber is monitored with OTDR technology.
If will realize the whole fiber optic network of monitoring in prior art, need a large amount of optical switch and OTDR, existing OTDR module approaches 100,000, and therefore the construction cost of whole monitoring system will sharply increase.
Utility model content
For the problems referred to above, the utility model provides a kind of optical fibre fault monitoring system, and low cost realizes the fiber-optic monitoring of whole optical fiber distributing network, networking mode simple and flexible, simple.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
A kind of optical fibre fault monitoring system, comprise the monitoring center that is positioned at central site, described monitoring center comprises OTDR, it is characterized in that, described OTDR is connected with the IN interface of the first optical switch by optical patchcord, the OUT interface of the first optical switch is connected with the IN interface of the second optical switch of several transfer websites by optical fiber, the OUT interface of described the second optical switch is connected with the IN interface of the optical splitter of user side website by optical fiber, and the OUT interface of described optical splitter is connected with several user side Optical Network Terminal by optical fiber.Preferably described the second optical switch is rack optical switch.
Traditional monitoring center is made up of OTDR, server, monitoring net guard system, is the control centre of whole system, and monitoring center sends test and switching command to OTDR, optical switch, analyzes and judges test result, and calculate fault point particular location.The monitoring net guard system of system provides WEB service in addition, and monitoring operation is carried out at convenient multi-purpose family simultaneously remote entry system, the line correlation of going forward side by side operation.
Consider the features such as optical fiber distributing network transmission range is relatively little, networking mode is complicated, client is comparatively scattered, only apply PON OTDR method and (place in monitoring center the RTU home site equipment that full configuration is put, all the other site configuration RTU secondary site equipment, by the OCS module in secondary site RTU equipment, realize multiple user side fiber optic cable monitors), need many cover OTDR equipment, and then increase the construction costs such as network operation, monitoring.The utility model application remote machine posture optical switch replaces OTDR equipment, and in conjunction with PON OTDR method, low cost realizes optical fiber distributing network Cable's Fault pattern is identified.
In order to distinguish different website functions, by the website called after central site that comprises monitoring center, the website called after user side website being directly connected with user side Optical Network Terminal, and mainly play the website called after transfer website of transfer effect.Website centered by OTDR scanning curve path → transfer website → user side website → user side Optical Network Terminal, by OTDR scanning curve is analyzed, can know the real time status of central site to user side optical fiber, can judge whether normal operation of this fiber segment, and further to disconnected fine, bending, deteriorated etc. the identification of fiber failure pattern, thereby the fiber-optic monitoring function of realization to optical fiber distributing network.
The beneficial effects of the utility model are: low cost realizes the fiber-optic monitoring of whole optical fiber distributing network, networking mode simple and flexible, simple.
