Description
Technical field
The present invention relates to the optical-fibre communications equipment technical field, but specifically a kind of light of on-line monitoring FTTH network reflects quick coupler and manufacturing process.
Background technology
In recent years, the user constantly increases for the demand of bandwidth, and the bandwidth of asymmetric user line (ADSL) access way will become the bottleneck of network application in the near future.And the advantage that Fiber to the home (FTTH) aspect bandwidth is so that it becomes the ideal orientation of future network access development, because it can satisfy user's multiple demand, the communication of image height speed, home shopping, real time remote education, video request program (VOD), high-definition television (HDTV) etc., but these business all are the targets that copper cash or twisted-pair feeder are exerted oneself to the utmost and just can be reached, and then are easy concerning FTTH.The remarkable technical characterstic of FTTH is the bandwidth that not only provides larger, and strengthened the transparency of network to data form, speed, wavelength and agreement, relaxed requirements such as environmental baseline and power supplies, simplified and safeguarded and installation, has the ability of transmitting simultaneously TDM, IP data and video broadcasting, wherein the form of TDM and IP the data IEEE 802.3 Ethernets transmits, be aided with the carrier-class network management system, be enough to guarantee transmission quality, can realize the video traffic broadcasting transmitting by expanding the 3rd wavelength (being generally 1550nm).
FTTH refers to optical network unit (ONU) is installed in household user or enterprise customer place, be optical fiber in X place (FTTx) series except fiber to the desk (FTTD) the most close user's optical access network type.By EPON (PON), FTTH can make a plurality of users share single optical fiber connection, and need not to use any active component, namely generate and change the element of light by photoelectricity light (OEO) conversion, thereby greatly reduce network installation, administer and maintain cost.The various related widebands that rise are at present used so that have the optical fiber of the good characteristics such as high bandwidth, large capacity, low-loss becomes the inevitable choice that data is sent to the medium of client.
Under the environment of extensive, multi-user unit, how to safeguard that the integrality of PON becomes problem in the urgent need to address.Therefore, implement the on-line monitoring and management to PON, have important practical significance.The service of voice, data and image can be provided for the user based on the broadband network structure of FTTH, and an important prerequisite is the integrality that will keep and monitor the FTTH network link.Optical time domain reflectometer (OTDR) is by general instrument as optical network link is tested.It is the method that adopts time domain measurement, emission has the light pulse of certain width and injects tested optical fiber, then by the Rayleigh scattering returned in the detection fiber and the Fresnel reflection optical signal power distribution curve along time shaft, can find out the physical characteristicss such as the length of tested optical fiber and loss, simultaneously, utilize its powerful data analysis function, can accurately locate the case point in the optical fiber link and trouble spot.
In the PON framework, in the central office, service links to each other by the same optical distribution of optical line terminal (OLT) (ODN) PSTN (PSTN) with Intemet.Three wavelength (1310,1490 and 1550nm) light transmits the different information of uplink and downlink simultaneously on same optical fiber.And OTDR also have 1310,1490,1550,1625 and the available optical network link that carries out of 1650nm equiwavelength measure.Measurement for the network link integrality, focus on checking OLT to ODN, ODN unimpeded to the link of each ONU, by verifying whether correct each section fiber distance and when construction compare, simultaneously, also can form database confirms and fault point locating the quality of optical network link for being convenient in the future operator's on-line monitoring test, the maintenance.At present, OTDR is in the optical network link integrity test, if use 1310,1490 and the signal of 1550nm transmission wavelength test then can cause to voice, data or the signal of video signal that is transmitting on the optical-fiber network to a certain degree interference, but this problem is not also paid attention at present and is solved.
There are at present a variety of considerations to come to be OTDR with the optical maser wavelength of 1620nm or 1650nm the 1310nm that need to use to avoid proper communication, 1490nm, 1550nm equiwavelength.But in the system of PON, each user side needs to increase the reflection end of a 1620nm or 1650nm, and cost is had very high requirement.Simultaneously, at present FTTH networking construction center of gravity is turned to indoor by the open air, and environmental evolution brings a series of difficult problems of network design.In the FTTH research field, except integrated services, the choice of technology, system equipment, outline also comprises: fiber-optic cable, reduce indoor construction difficulty and network O﹠M cost, internal home network is disposed and link is efficiently opened and O﹠M becomes the focus of attention of FTTH networking.Therefore, increase a light reflection device if monitor for the integrality of auxiliary networking link merely, not only dispose more complicated, also increased the overall cost that the FTTH internal home network is disposed simultaneously.
