General Dynamics' SATCOM Technologies is pleased to announce the immediate availability of a new, state-of-the-art, low-cost SCPC satellite modem: the Model 8450.
Marvin Shoemake, Vice President Business Development at SATCOM Technologies, said, "The Model 8450 is a new, cost-effective modem for the satellite transmission market introduced in response to market demand for spectral efficiency in a low bandwidth modem."
"Designed principally for satellite data transmission applications, the Model 8450 is a natural choice for satellite transfer rates from 64Kbps up to 30Mbps. In full duplex mode, the Model 8450 can simultaneously send and receive a total of 60Mbps per unit. Like SATCOM Technologies' successful Model 8550 modem, the new Model 8450 employs DVB S2 as the basic satellite transmission standard. The Model 8450 supports DVB-S, DVB-S2 with 5% Roll-off Filter (ROF), DVB-S2X and NS3 which typically boosts spectral efficiency by 30% to 60% compared with DVB-S2 equipment," Shoemake said.
Equipped for data transmission, the Model 8450 comes with four E1/T1 interfaces for cellular backhaul and two ASI interfaces for video and Gigabit 1000Base-T. It also has built-in hardware support for LDPC advanced FEC, NS3 and DUET CeC (Carrier-Echo-Cancellation).
The Model 8450 supports point-to-point and point-to-multipoint links and incorporates a high-efficiency NSPE™ encapsulation scheme. The Model 8450's integrated IP processing unit also supports a wide range of features such as advanced QoS (Quality of Service), transparent bridging, VLAN switching, routing mode and header and payload acceleration.
In addition, the Model 8450 platform offers such performance-boosting options as Adaptive and Variable Coding Modulation, Automatic Uplink Power Control, Carrier ID compliance and Dual channel support for simultaneous Asynchronous Serial Interface and Internet Protocol streams.
"All of these features make the Model 8450 the ideal low-data rate modem for cellular backhaul, IP trunking and other data services applications, not to mention a valuable asset for broadcasters' DSNG services," Shoemake added.
"The Model 8450 modem provides all the advanced IP processing features and efficiency of the very successful Model 8550 modem at a price that fits the business models of lower throughput data applications."
"When you look at the Model 8450's full range of capabilities, it becomes immediately clear that there isn't a comparable product in the market," Shoemake added.
Following is a partial list of the Model 8450's features - all contained in a space-saving, 1RU package:
- Data rates to 30 Mbps (bidirectional 60 Mbps)
- NS3 coding with frequency "roll off" as little as 5%
- Fully integrated IP solution with routing, switching and bridging capabilities
- DVB-S2, DVB-S2X, DSNG compliant
- Adaptive Coding Modulation (ACM) and Dynamic Automatic Uplink Power Control features for superior bandwidth optimization
- Dynamic Distortion Compensator (DDC) automatically characterizes and compensates for non-linearity, such as that introduced when the transponder power amplifier is saturated
- Jamming, Phase Noise, Weather Fluctuation, Doppler and interference resilience
- Supports QPSK, 8PSK, 16APSK, 32APSK and 64APSK modulations
- Control via web browser or SNMP
- Over-the-air M&C and Software upgrade capability
