TXP Co. says RF return capable in ONT

 coaxial cable wire TXP Corporation (OTCBB: TXPO), an Original Design Manufacturer(ODM) for the telecommunications industry, has introduced the firstof its standards-compliant RF return capable Optical NetworkTerminals (ONT), giving service providers a practical solution fordelivering video and television services to residential customersover GPON while maintaining backward compatibility with existingset-top boxes (STB). TXP' s RF return implementation is compliant with FSAN standards forthree-wavelength GPON deployments, as well as SCTE 55-1 and 55-2standards that support STBs from the two major brands – Motorola and Scientific-Atlanta. TXP has proven interoperabilitywith 16 OLT platforms and is capable of working with anystandards-based OLT. This broad-ranging interoperability, coupledwith RF return and all supported through a common software load,makes TXP ONTs almost universally deployable. "Backwards compatibility with existing set-top boxes is a majorconcern for telcos contemplating GPON deployments, which is why TXPclosely followed all the relevant standards in our implementationof RF return, ” said Joel Futterman, General Manager of TXP ’ s ONT Solutions Group. “ This capability in optical network terminals opens the door forwide-ranging deployment of interactive video services over GPONwithout the need to replace thousands of existing set-top boxes. ” RF return enables telcos to install ONTs at the customer site andinteroperate with existing coaxial cable wiring and set top boxes.The RF return channel in the current model is used as an upstreampath for customers to send data to the service provider, such asrequesting pay-per-view broadcasts or other video on demandapplications. The coaxial cable connects directly to the ONT, andthe standard 1310 nm GPON wavelength is used for the upstreamtransmission of voice, data, and video RF return traffic. The TXP standards-compliant approach is in contrast to otherrecently announced approaches that require a fourth wavelength inorder to enable an RF return channel. As Futterman noted, “ There is no ratified standard involving a four-wavelength RF returnsolution over GPON, and under competitive pressure from cableoperators, telcos simply don ’ t have the time to wait. The three-wavelength approach adds lesscost to the ONT, requires less overall equipment per PON and doesnot limit PON reach like competing four-wavelength RFoG solutions. ”
