( oti ) legacyplus series of replacement & upgrade modules for installed hfc optical nodes is a high performance, low cost, field proven group of custom engineered products specifically designed to upgrade the functionality of installed optical nodes from many major manufacturers by dramatically increasing upstream or downstream bandwidth without having to replace optical nodes or deploy extra fiber, 1550nm itu grid dwdm lasers, baseband digital reverse modules, or other expensive return path segmentation technologies. olson technology, inc. ( oti ) legacyplus isx-30xx return path transmitter modules have been specifically designed so that node modules can be replaced, if needed, with any module or unit of the same type and the same optical and electrical specifications from adc/c-cor, the original manufacturer of the isx-30xx node family. hence, the replacement of a node based return path transmitter module does not require replacement of the corresponding headend optical receiver or vice versa. legacyplus products provide outstanding return path performance, system design flexibility and scalability in almost any network architecture from traditional hybrid fiber coax (hfc) to the newer fiber deep targeted service delivery (tsd) area topologies. there are two general types of reverse transmitters available: (1) fabry-perot (f-p) type, which are lower priced and designed for low traffic data carrier transmission applications with less stringent performance requirements (i.e. element management, set top box communications, etc.), and; (2) dfb/cwdm-type, which support analog video channels and/or high capacity data traffic (i.e. internet access, telephony, etc.). the introduction of voip telephony adds even tougher constraints to return path performance. originally deployed f-p transmitter modules tend to exhibit laser clipping. one of the end results of clipping is packet loss, which is very detriment al to voip. legacyplus dfb & cwdm tx modules, with their inherently higher dynamic range, provide cost effective and robust migration alternatives to f-p laser reverse transmitters during pre-voip plant upgrades. in addition to the many ?standard? legacyplus modules currently available to system operators, olson technology, inc. ( oti ) continues to work with msos to define, refine, develop and manufacture new solutions custom tailored to their individual system requirements. for the latest information or to discuss possible module availability or design for unlisted nodes, pleas e contact olson technology, inc.
