FP, DFB (1310 or 1550nm) or CWDM (ITU-grid 1470-1610nm) laser return path optical transmitters
For installed base of Arris/Antec Model # LLRX200 Gateway II HFC optical nodes
Performs significantly better than or equal to the original Model RDL/RVD modules
To minimize clipping in VoIP deployments, 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
Field proven since 1999: Olson Tx & Rx modules successfully deployed in 1000’s of nodes worldwide
Low power consumption & good heat dissipation for increased service life and reliability
Low Cost; Stable operation over Time, Temperature and Signal Loading; Convenient test points
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 LLRX200 Return Path
Transmitter Modules have been specifically designed so that node mod-
ules can be replaced, if needed, with any module or unit of the same type
and the same optical and electrical specifications from Arris/Antec, the
original vendor/supplier of the LLRX200 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 requirements (i.e. element management,
set top box communications, etc.), and; (2) DFB/CWDM-type, which sup-
port analog video channels and/or high capacity data traffic (i.e. Internet access, telephony, etc.).
The introduction of VoIP services adds even tougher constraints to return path performance. Originally deployed FP return path
transmitter modules tend to exhibit laser clipping. One of the end effects 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 FP laser return transmitters during pre-VoIP plant upgrades.
In addition to the many “standard” LegacyPlus modules currently available to system operators, OLSON TECHNOLOGY, INC.
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 contact
