Mark,
remember that HLIT's head of national sales was head of sales at NLV a short time ago. As to what modulation schemes HLIT uses,its QAM,which has greater compression,and uses less bandwidth than QPSK.
QPSK is the standard MCNS upstream modulation due to its availability and robustness.
TRANsend QAM Modulator (QMM 8000)
The Harmonic Lightwaves TRANsend QAM is a high performance QAM modulator
and up-converter module for the transmission of advanced digital
services over analog broadband networks. The module is compact and
space-efficient, fitting up to five modulator/up-converters in the three
rack unit HLP 4000WD platform. The modulator accepts an MPEG-2 compliant
digital video, audio and/or data transport stream or a clear channel
data stream, and outputs a quadrature amplitude modulated (QAM) RF
signal in the 45 to 870 MHz frequency range, or an intermediate
frequency (IF) signal of either 44 MHz or 36.15 MHz center frequency. A
single modulator can support MPEG-2 data rates up to 52.2 Mbps for an 8
MHz channel allocation and up to 39.1 Mbps for a 6 MHz channel.
The TRANsend QAM modules are compact, intelligent and easily
configurable by means of the user-friendly interface, allowing for
set-up in minutes. The modules can be set up via the HLP 4000WD platform
front panel menu or via the NETWatch Element Management System. The
modulator is highly flexible and easily configured for IF/RF output
frequency, level and QAM constellation size (4, 16, 32, 64, 128 or 256
QAM), widely variable data rate and bandwidth, and any one of the
required industry standards for interfacing and signal processing.
This is basically what HLIT is using. I believe their new products will sell fantastically well this year. And I believe New Media will be accretive to earnings in the second quarter. This quarter looks good,and the first and second quarter's look fantastic. If revenue is over 20 million this quarter,watch out,they are going to have a great year.
