metrical bandwidth.Because the WDM splitter can bepackaged in the same form factor asexisting splitters, service providers caninsert a module into an existing GPONfiber distribution cabinet to supportWDM-PON. This allows service providersto offer residential services viaGPON and commercial services viaWDM-PON. And as their residentialcustomers demand more bandwidth,they can simply move the distributionfiber from one splitter to the other andprovide up to 1 Gbps without servicedisruption to the GPON network.Benefits for the service provider include:• The ability to use “colorless” OLTsand ONTs solves a major cost problemwith WDM-PON• Plug-and-play simplicity reducestime to market and eliminates wavelengthmanagement issues• Reuse of existing fiber distributionproducts• Service and bit rate upgrades withoutinfrastructure changes• Coexistence with GPON to deliverresidential and business services fromthe same fiber distribution cabinet• Simplification of the upgrade pathfrom GPON to higher bandwidthsupport for services such as IPHDTV.In-hub splicing: ADC also introducedan in-hub distributionsplice option for theOmniReach Fiber DistributionHub (FDH) 3000,for situations where splicecase access beyond the hubis either not available or notdesirable. The new spliceconfiguration is availablein three cabinet sizes (144,288 and 432). Cables arespliced using a fiber splicewheel, which accommodatesvariable lengths ofpigtails and buffer tubes.The splice option allows users to integratedistribution cable splicing within hubs,rather than splicing to cable stubs thatare in splice cases located as far as 100feet away.The FDH 3000’s centralized splitterapproach maximizes space on costly opticalline terminal cards. In addition, it offersbend radius protection, intuitive cablerouting, easy fiber/connector access andphysical protection from the elements.CLASSIFIED ADSJuly 2008 | www.broadbandproperties.com | BROADBAND PROPERTIES | 103
