Description
Technical field
The utility model relates to broadband access technology, is specifically related to a kind of integrated access equipment.
Background technology
Broadband access technology commonly used at present mainly comprises Digital Subscriber Loop (DSL, Digital Subscriber Loop) technology, optical fiber access technology and hybrid fiber/ coax, HFC (HFC, the Hybrid Fiber-Coaxial) access technology based on copper cash.
DSL is a technology of utilizing the ordinary copper telephone line transmission high-bandwidth information in the conventional fixed telephone network.The DSL system mainly is made up of digital subscriber line access multiplex (DSLAM, Digital SubscriberLine Access Multiplexer) and client device (CPE, Customer Premises Equipment).The high-frequency digital modulation signal of network side through DSLAM carry out multiplexing after, be transferred to CPE by fixed telephone network; The high-frequency digital modulation signal of cpe side is transferred to DSLAM through fixed telephone network, by DSLAM multi-user's high-frequency digital modulation signal is transferred to network side, realizes the transmission of high-bandwidth information.
Owing in the DSL system, utilize the signal of ordinary copper telephone wire transmission to decay rapidly along with the increase of distance, and the bandwidth of transmission signals and distance can not get both, and therefore, limited it and independently brought into play the function of broadband access.DSL also generally uses at present, mainly be because existing DSL bandwidth satisfies access demand reluctantly, but, along with people are increasing to the demand of access bandwidth, for example, the Email of transport tape photo, family's picture control, video communication, Video chats such as MSN and QQ etc. all need very high upstream bandwidth, and DSL is because its intrinsic shortcoming can't continue to adapt to networks development.
The optical fiber access technology is an all or part of employing optical fiber in Access Network, constitutes FITL, realizes a kind of technology of broadband access.Optical access network comprises user side, optical network unit (ONU, OpticalNetwork Unit), optical fiber distributing net (Optical fiber Distribution Network), optical line terminal (OLT, Optical Line Terminal) and service node.ONU will be transferred to OLT by ODN after will being converted to light signal from the upward signal of user side, and OLT is converted to the signal of telecommunication with light signal, is transferred to service node; Simultaneously, OLT will be converted to light signal from the downstream signal of service node, be transferred to ONU by ODN, by ONU light signal will be converted to the signal of telecommunication, be transferred to user side again; ONU also can provide E1 interface and Ethernet interface.Wherein, ONU also can carry out modulus and digital-to-analogue conversion to the voice signal that receives, and the voice signal that receives is separated with data-signal and converges; OLT has the function that the voice signal that will receive separates and converges with data-signal.
Position according to ONU, Optical Access Network is divided into fiber to the desk (FTTD), Fiber to the home (FTTH, Fiber To The Home), Fiber To The Building (FTTB), Fiber-To-The-Office (FTTO), fiber-to-the-floor (FTTF), FTTC several types such as (FTTZ).Wherein, FTTH is meant ONU is installed in the user place.FTTH technology based on P2P is the Ethernet tranmission techniques that a kind of point-to-point optical fiber connects.This technology utilizes wavelength division multiplexing (WDM, Wavelength DivisionMultiple) that the up-downgoing wavelength is transmitted in an optical fiber, and each user only needs an optical fiber can realize two-way communication.
Because FTTH provides conventional fixed phone cost to be higher than existing landline telephone technical costs far away, and utilize FTTH to realize that also there is the phone powerup issue in the conventional fixed phone.Therefore, can't utilize existing FTTH that the conventional fixed phone is provided.
HFC is the hybrid network that optical fiber and coaxial cable combine.HFC is made up of fiber optic backbone, coaxial cable branch line and subscriber distribution network network three parts usually, is converted to light signal earlier from the programme signal of cable TV station output and transmits at fiber optic backbone; Light signal converts the signal of telecommunication to behind the user area, is transferred to the user by coaxial cable and subscriber distribution network network after distributor distributes.
The shortcoming of HFC technology is to need bidirectional rebuilding.The design of hfc plant at present mainly designs in the multicast mode, has only downlink bandwidth, and does not have upstream bandwidth.If be applied in the broadband access technology,, then need to transform existing downlink bandwidth as two-way bandwidth in order to adapt to the increasing network development of bandwidth demand.Therefore, need carry out bidirectional rebuilding, engineering construction and system debug are comparatively complicated, and unpredictable element is more.
By the above as can be known, several broadband access technologys that exist can only solve the corresponding business demand, and can't satisfy various access demands simultaneously at present.And if respectively above several access technologies were carried out all-round construction, then construction cost height, cycle length, construction and O﹠M would be also inconvenient.
