Description
Technical field
The present invention relates to optical-fibre communications equipment technical field, specifically one is the SC type Hermaphrodite fiber adapter with fixed wave length light filter function that the optical network unit (ONU) that one was configured in time-division Wavelength division multiplexing-passive fiber optic network (TWDM-PON) is held.
Background technology
FTTH is a kind of final form of access network development, Optical Access Network (be referred to as FTTx), with the place, position of ONU, is divided into fiber to the home (FTTH), Fiber To The Building (FTTB) and Fiber To The Curb several situations such as (FTTC).From the point of view of house or building, connect user with optical fiber, mainly have two ways: one is to be directly connected to each family or building with optical fiber；Another kind is to use passive optical-fiber network (PON) technology, with beam splitter, optical signal is carried out branch, and an optical fiber provides fiber-to-the-home front yard to service for multiple users.PON technology is exactly to comply with this burst of trend and move towards the broadband access technology of a kind of super quality and competitive price in market.PON refers to that optical fiber distributed type network (ODN) does not contains any electronic device and electronic power supply, and is all made up of passive devices such as optical branching devices.The outstanding advantages of PON is a cancellation the active equipment of open air, and all of signal processing function all completes at switch and station equipment.Along with the driving of broadband, various countries policy and the sustainable growth to bandwidth demand, present Optical Access Network initially enters the epoch laid on a large scale, and the scheme of " last one kilometer " has begun to conscientiously carry out.The upgrading of whole broadband or " light entering and copper back " basically, are whole infrastructure construction problems, and its investment is huge, and operator wishes that network has once been built, it would be desirable to can run for a long time；Avoid, because upgrading or dilatation, causing the big variation to existing network as far as possible.Therefore in the selection of access network technology and scheme, it is necessary to consider to coexist this key problem, and the ODN being i.e. made up of single-mode fiber and optical branching device needs to remain motionless in a long time.
The PON system of current main-stream includes the gigabit passive optical network (GPON) worked out by International Telecommunication Union (ITU) and FSAN forum (FSAN), and the Ethernet passive optical-fiber network (EPON) worked out by IEEE802.3ah working group of American Electronic electric association.They have identical up-downgoing wavelength, i.e. 1310nm and 1490nm.And the up-downgoing wavelength that next generation's 10GPON system uses is 1270nm and 1577nm.Thus, between two generation PON system, can co-exist on an ODN by wavelength division multiplex device, bandwidth upgrading does not affect original business.Currently, the standard stipulation at 10G-GPON (also known as XG-PON1) and 10GEPON works and the most completes, GPON and EPON is commercial on a large scale simultaneously, and XG-PON1 has begun to commercial deployment.The NG-PON technical scheme in rear 10G-PON epoch starts to show up prominently.
NG-PON technology is divided into two classes, is NG-PON1 and NG-PON2 respectively.NG-PON1 is incremental PON technology, and it supports to coexist in same ODN network with GPON, and this characteristic can allow individual user's seamless upgrade to NG-PON, and will not interrupt the service of other users；NG-PON2 technologically speaking, is huge change, has completely disengaged from original EPON, GPON and has limited, it is intended to from network architecture angle, proposing a kind of brand-new PON technology, NG-PON2 is also regarded as a long-term solution simultaneously, and is the PON technology of future generation after NG-PON1.NG-PON2 is not limited concurrent conditions to be possessed, but coexists and be not precluded from.PON technology under NG-PON1 has obtained widespread deployment in existing network, and 10G-PON, as the evolution in mid-term of PON technology, is also conceived to take into account existing PONODN system, protects existing investment, promotes broadband access speed.NG-PON2 is then considered the developing direction at a specified future date of PON, and is considered PON technology of future generation.NG-PON2 has plurality of optional technology, mainstream technology includes Wavelength division multiplexing-passive fiber optic network (WDM-PON), orthogonal frequency division multiplexing passive fiber optic network (OFDM-PON), time-division wavelength-division stacking multiplexing passive optical networking network (TWDM-PON), CDMA passive optical-fiber network (OCDMA-PON), high speed time division multi-address passive fiber optic network (TDMA-PON) etc., and the standard of NG-PON2 is moved towards to be concerned about very much by industry.In June, 2012, in the standards meetings of FSAN tissue, NG-PON2 standard obtains breakthrough, and TWDM-PON is confirmed as main NG-PON2 standard.
TWDM-PON is that stacked TDMPON, the TWDM abbreviation of 10G itself by multiple wavelength channels be the abbreviation combining time division multiplexing tdm and wave division multiplexing WDM；From the point of view of technical standpoint, the natural characteristic inheriting 10G-PON of TWDM-PON, it is not necessary to change the ODN network that operator has laid, closest to GPON or XG-PON1 being widely deployed in agreement, it is the Natural circulation~+ of GPON and XG-PON1, it is achieved the bandwidth of existing network promotes and smooth evolution.Because it is optimal that the network of operator is inherited evolution characteristic by this standard, obtain being widely recognized as and promoting of all multi-operators, chip manufacturer and equipment vendors.Meanwhile, if power budget problem can be solved, that TWDM-PON can support the user more than 256 and longer distance, it is achieved the upgrading of FTTB/FTTC to FTTH, and realizes end office (EO) (CO) fusion.On the other hand, owing to there is multiple wavelength in same ODN, and each ONU can select or reconfigure other wavelength, and this makes multiple operator share same network to be possibly realized.
Fig. 1 is the frame diagram that TWDM-PON with G/E-PON and 10G-PON coexists.TWDM-PON is to utilize 4 to different up-downgoing wavelength, and original 10G-PON dilatation is become original four times.In order to realize and the coexisting of legacy network, the wavelength of 40G-PON needs again to plan, avoids that 1577nm and 1490nm be descending and the up wave band of 1270nm and 1310nm.Owing to introducing multiple wavelength in same PON, the laser instrument therefore producing different wave length and the optical filter leaching specific wavelength become the Primary Component of TWDM-PON technology.Four descending wavelength (undetermined) arrive all of ONU after optical branching device.Therefore, each ONU is required for being equipped with a miniaturization and the optical filter of low cost, picks out the specific downgoing communication wavelength for this ONU.
