subject: Fttx Solutions To Create Unlimited Bandwidth Full Service Access Network-fttx Solutions For Optical [print this page] Currently, the Internet and multimedia applications and telecommunications services market growing increasingly competitive, to promote a number of fixed network operators are from pure providers of broadband pipes integrated information service provider to change, and hope to the end through the deployment of converged networks provide wire-speed full-service, get more revenue. The deployment of emerging business, operators need to carry on the existing network to further enhance and integrate. Then, access network has become an important part can not be ignored. You can see, the world's major carriers are adopting a multi-access network technology for large-scale reconstruction and construction.
The network deployment, the light of Copper is a global development strategy of the current operators, that is, through a variety of FTTx deployment to achieve deep optical fibers. The fiber to the home than to promote FTTH is the ultimate goal, FTTB / FTTN is more economical at this stage deployment mode.
To achieve their function, can be summarized as "high-bandwidth, full-service, fat terminals, unified management," that have high enough bandwidth to meet in order to advance high-definition video-based high bandwidth services demand; to has also hosted a variety of business and strict security capabilities to achieve QOS; be able to extend the operator's network to the home network and the integration of various business home gateway equipment; have a can simultaneously manage all user access technologies and collaborative management integrated circuits and home network management platform.
Combination of multiple technologies for full service access
GPON, VDSL2, RG, and WIFI and many other technologies combine to achieve the above objectives, to meet current and future deployment of all business requirements.
GPON is a full service carriers operating into the era of the best broadband optical access technologies, operators can build consistent long-term health development goals of the access network. GPON in terms of bandwidth, splitting ratio, transmission distance, the still of the TDM service support, multi-business QOS guarantees and OAM capabilities than the great advantages of EPON is very suitable for FTTH / FTTB deployment. The past two years, GPON global large-scale deployment has started, the famous operator Verzion, AT & T has shifted from large-scale deployment of the testing phase, the European market from the scale of deployment of the end of 2007, the Asian markets such as Korea, Singapore, the GPON business began rapid development, has announced plans to build commercial and mainstream GPON operators more than 40.
FSAN in October 2007 OMCI interoperability testing organizations, each independently developed GPONOLT manufacturers and other manufacturers were ONT OLT and ONT were registered interoperability testing, OMCI management interoperability testing and triple-play interoperability testing. Between OLT and ONT manufacturers of all the good exchange, marking the troubled large-scale application of the interoperability problem FTTH made significant progress, with large-scale commercial conditions. The GPON interoperability test of success is FSAN in January 2007 and May to conduct interoperability testing has been another important milestone in the organization is following the China Telecom GPON system provider for functional verification test is another important progress . U.S. carriers Verizon's FSAN Interoperability Working Group Chairman MichaelBrusca said: "At present, GPON equipment has mature model with large-scale deployment conditions. Which Alcatel-LucentGPON optical access products? 7342ISAMFTTU either OLT or ONT are to be completed with other major equipment providers in the registration, ranging interoperability layer such as TC, with the major ONT / OLT vendors to complete, including the OMCI interoperability. "
2008 beginning at China Telecom and China Netcom's OMCI interoperability testing organizations, Alcatel-Lucent GPONOLT / ONT has been achieved and Huawei ONT / OLT unicast and multicast services of full-scale, in the ASB and the mainstream equipment manufacturers together efforts to achieve expected business in the first half-round exchange.
VDSL2 same as a new technology VDSL2, European and American carriers have begun a large scale from 2007 to deploy,
Global deployment of the next five years to more than 100 million lines. The technology has matured, the compatibility of the terminal has also been greatly improved. At present, many commercial VDSL2 chip set can be achieved are backward compatible with ADSL2 +, VDSL2 technology not only to combine GPON FTTB deployment is the deployment of GE + FTTN model a good choice.
