Description
Technical field
The utility model relates to joints of optical fibre technical field, a kind of SC type joints of optical fibre with light filter function specifically, and it is disposed at optical network unit (ONU) end in the time-division Wavelength division multiplexing-passive fiber optic network (TWDM-PON).
Background technology
FTTH is a kind of final form of Access Network development, and Optical Access Network (general designation FTTx) is with the place, position of ONU, several situations such as (FTTC) that are divided into that Fiber to the home (FTTH), Fiber To The Building (FTTB) and Fiber To The Curb.For dwelling house or buildings, connect the user with optical fiber, mainly contain dual mode: a kind of is directly to connect each family or building with optical fiber; Another kind is to adopt passive optical-fiber network (PON) technology, with optical splitter light signal is carried out branch, and an optical fiber provides the service of fiber-to-the-home front yard for a plurality of users.The PON technology is exactly to comply with this burst trend and the broadband access technology that moves towards a kind of super quality and competitive price in market.PON refers to optical fiber distributed type network (ODN) without any electron device and electronic power supply, and all is comprised of passive devices such as optical branching devices.The outstanding advantages of PON network is to have eliminated outdoor active equipment, and all signal processing functions are all finished at switch and station equipment.
Along with the driving of broadband, various countries policy and to the sustainable growth of bandwidth demand, Optical Access Network begins to enter the epoch that lay on a large scale now, and the scheme of " last kilometer " has begun practical implementation.The upgrading of whole broadband or " light entering and copper back " are whole infrastructure construction problems in essence, and its investment is huge, and operator wishes network in case build and finish, and just wish and can run for a long time; Avoid because upgrading or dilatation cause the large change to existing network as far as possible.Therefore in the selection of access network technology and scheme, must consider this key problem of coexistence, the ODN that namely is made of single-mode fiber and optical branching device need to keep motionless in long-time.
The PON system of current main-stream comprises the gigabit passive optical network (GPON) of being worked out by International Telecommunications Union (ITU) (ITU) and FSAN forum (FSAN), and the Ethernet passive optical-fiber network (EPON) of being worked out by IEEE802.3ah working group of the electric association of the U.S..They have identical up-downgoing wavelength, i.e. 1310nm and 1490nm.And the up-downgoing wavelength that 10G PON of future generation system adopts is 1270nm and 1577nm.Thereby, between the two generation PON systems, can co-exist on the ODN by wavelength division multiplex device, bandwidth upgrading does not affect original business.Current, all finish in the standard formulation work of 10G-GPON (also being called XG-PON1) and 10G EPON, GPON and EPON are commercial on a large scale simultaneously, and XG-PON1 has begun commercial the deployment.The NG-PON technical scheme in rear 10G-PON epoch begins to show up prominently.
The NG-PON technology is divided into two classes, is respectively NG-PON1 and NG-PON2.NG-PON1 is incremental PON technology, and it supports to coexist as in the same ODN network with GPON, and this specific character can allow individual user's seamless upgrade to NG-PON, and can not interrupt other users' service; NG-PON2 technologically speaking, it is huge change, broken away from original EPON, GPON restriction fully, be intended to from network frame structure angle, a kind of brand-new PON technology is proposed, NG-PON2 also is regarded as a long-term solution simultaneously, and is the PON technology of future generation after NG-PON1.NG-PON2 is not limited to possess concurrent conditions, but coexistence is not got rid of.PON technology under the NG-PON1 has obtained widespread deployment in existing network, 10G-PON is as the evolution in mid-term of PON technology, also is conceived to take into account existing PON ODN system, protects existing investment, promotes broadband access speed.NG-PON2 then is regarded as the developing direction at a specified future date of PON, and is considered PON technology of future generation.NG-PON2 has the plurality of optional technology, mainstream technology comprises Wavelength division multiplexing-passive fiber optic network (WDM-PON), orthogonal frequency division multiplexing passive fiber optic network (OFDM-PON), the stacking multiplexing passive optical networking of time-division wavelength-division network (TWDM-PON), CDMA passive optical-fiber network (OCDMA-PON), high speed TDMA passive fiber optic network (TDMA-PON) etc., and industry is concerned about the standard trend of NG-PON2 very much.In June, 2012, on the standards meetings of FSAN tissue, the NG-PON2 standard obtains breakthrough, and TWDM-PON is confirmed as main NG-PON2 standard.
TWDM-PON is the TDM PON that comes stacking 10G by a plurality of wavelength channels, and the TWDM abbreviation itself is the abbreviation in conjunction with time division multiplexing tdm and wave division multiplexing WDM; From technical standpoint, the natural characteristic of inheriting 10G-PON of TWDM-PON does not need to change the ODN network that operator has laid, the GPON of the most approaching widespread deployment or XG-PON1 on agreement, be the natural evolution of GPON and XG-PON1, realize that the bandwidth of existing network promotes and smooth evolution.Because it is best that this standard is inherited the evolution characteristic to the network of operator, extensive approval and the promotion of all multi-operators, chip manufacturer and equipment vendors have been obtained.Simultaneously, if can solve the power budget problem, then TWDM-PON can support to surpass 256 user and longer distance, realizes FTTB/FTTC to the upgrading of FTTH, and realizes end office (EO) (CO) fusion.On the other hand, owing to have a plurality of wavelength among the same ODN, and each ONU can select or reconfigure other wavelength, and this becomes possibility so that same network is shared by a plurality of operator.
Fig. 1 is the frame diagram of TWDM-PON and G/E-PON and 10G-PON coexistence.TWDM-PON utilizes 4 pairs of different up-downgoing wavelength, and original 10G-PON dilatation is become original four times.In order to realize and the coexistence of legacy network that the wavelength of 40G-PON needs again planning, avoids 1577nm and 1490nm descending and 1270nm and the up wave band of 1310nm.Owing to introduced a plurality of wavelength in same PON, the optical filter that therefore produces the laser instrument of different wave length and leach specific wavelength becomes the Primary Component of TWDM-PON technology.Descending four wavelength (undetermined) are through arriving all ONU behind the optical branching device.Therefore, each ONU needs to be equipped with a miniaturization and optical filter cheaply, picks out the specific downgoing communication wavelength for this ONU.
