LegacyPlus 7-OR Return Path Transmitter
FP, DFB (1310 or 1550nm) or CWDM (ITU-grid 1470-1610nm) return path optical transmitters
Compatible with the installed base of Philips/Magnavox 7-OR DiamondPoint HFC optical nodes
Performs significantly better than or equal to the original OEM modules
Reduced laser clipping in VoIP deployments via DFB or CWDM module replacement of FP lasers
Ideal for systems undergoing “node splitting” for return path segmentation purposes
Low cost alternative to DWDM transmitters, digital reverse & other node segmentation methods
RF test point (-10 dB) & Plug-in pad attenuator facilitate 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 functional-
ity 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 7-OR Return Path Trans-
mitter 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 Philips/Magnavox, the origi-
nal manufacturer of the DiamondPoint 7-OR node. Hence, the replacement
of a node based Return Path Transmitter Module does not require replace-
ment of the corresponding headend optical receiver or vice versa.
LegacyPlus products provide outstanding return path performance, sys-
tem 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 (FP) type,
which are lower priced and designed for low traffic data carrier transmission applications with less stringent performance require-
ments (i.e. element management, set top box communications, etc.), and; (2) DFB/CWDM-type, which support analog video chan-
nels 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 FP transmitter
modules tend to exhibit laser clipping and poor NPR performance. The end resultof 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 FP 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
