Teledyne Paradise Datacom (News - Alert), a provider of satellite modem and RF products and subsystems to satcom technology users, has demonstrated that its Q-Flex satcom modem can pass over 91.8 Mb/x of TCP accelerated IP.

Tony Radford, vice president of sales and marketing at Teledyne, said, “A pair of 96 Mb/s carriers were placed within the confines of a 36 MHz transponder, but if additional features of our modem were employed, we could place both carriers in a single transponder for an additional 50 percent savings.”

The demo was conducted for a teleport based in Atlanta as part of a “technology re-fresh.” The test showed that Q-Flex can deliver IF and L-band operation in a single unit, eliminating the need for additional hardware. The performance measurements covered both iPERF and WAN-Killer testing programs for an IF-up / L-band down operation.

The Q-Flex modems are configured with DVB-S2, 16APSK, 5/6 FEC in addition to the company’s proprietary XStream IP feature set featuring embedded TCP link acceleration and custom PXE encapsulation, said officials.

Q-Flex is based on SCPC modem technology that enables a flexible, software-defined modem with a universal hardware platform. Other features like higher data rates, carrier cancellation, and higher modulation can be added via software upgrades.

The powerful processor in the modem enables it to handle IP traffic effectively and the device can be fitted with all types of terrestrial interfaces. The Q-Flex modem also features XStream IP’s TCP acceleration, header and payload compression, dynamic routing, traffic shaping, encryption, and ACM. Its spectral roll-off ensures about 20 percent bandwidth savings.

Also the other bandwidth-saving features like Paired Carrier and FastLink LDPC; the LinkGuard signal-under-carrier interference detection tool; built-in spectrum and constellation monitors; and modulation up to 64QAM  makes Q-Flex an out-of-the-box solution for users.

Recently the Teledyne compact satellite modem, the Q-Lite was successfully integrated into Vislink’s Advent Mantis “MSAT” man portable data terminal and. The MSAT terminal is a highly-portable tri-band satellite antenna system specifically designed for rapid deployment in hostile environments.
