Comtech
Awarded $1.1 Million Equipment Order to
Support Satellite-Based High-Speed Data
Trunking
April 16, 2013
Comtech EF Data Corp., was
awarded a $1.1 million equipment order
by a telecommunications operator in
Asia. The operator will deploy the
equipment to support high-speed trunking
links transporting 880 Mbps of data
traffic. The modems supplied have a
combined ability to support over 3 Gbps
of total traffic through software
upgrades
Leveraging the DVB-S2 EN 302 307 LDPC/BCH
standard, the CDM-7XX Series provides a
blend of coding and forward error correction
(FEC) to ensure that the maximum satellite
traffic is transported for a given signal to
noise capacity. Utilizing ACM, the modems
can respond to changing link conditions by
automatically adjusting modulation and FEC
rates, which transforms link margin,
implementation margin and margin for antenna
pointing directly to improved throughput.
The K4 GZIP lossless compression engine
performs real-time compression of Ethernet
traffic and is capable of running at the
full rate of the modem, greatly increasing
satellite link throughput or reducing
required bandwidth. For added reliability
and to fully protect traffic paths, the
CDM-7XX Series provides redundancy support,
automatically switching data and IF signals
from the primary unit to the standby unit if
an equipment failure or undesired traffic
condition occur.
