F-P, DFB (1310 or 1550nm) or CWDM (ITU-grid 1470-1610nm) return path optical transmitters
For the installed base of ADC/C-COR ISX-30xx HFC optical nodes
Designed to perform significantly better than or equal to the original Model # IX40-RPTX modules
Reduced laser clipping in VoIP deployments via DFB or CWDM module replacement of F-P lasers
Also ideal for systems undergoing “node splitting” for return path segmentation purposes
DUAL LASER OPTION in the module to facilitate return path segmentation and/or redundancy
Plug-in pad attenuator facilitates easy adjustment of RF Input drive level
Convenient DC test point scaled to Optical Output power (1V/mW)
Low power consumption & good heat dissipation for increased service life and reliability
Field proven since 1999: Olson TX & RX modules successfully deployed in 1000’s of nodes worldwide
The
OLSON TECHNOLOGY, INC. ( 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 detrimental 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, please

** NOTE: Olson ISX-30xx DFB/CWDM R-TXs have minimum 7dB of additional gain available for CNR improvement in lower
channel or bandwidth loading scenarios. For example, if only 2 channels are used, the NPR curve (see graph) allows for an
additional 5 dB of RF input level without inducing laser clipping to improve the CNR level accordingly.
