Scalable Performance
The SE300X platform offers a wide range of performance boosting options including DVB-S2 with 5% ROF, ACM/VCM, AUPC (Automatic Uplink Power Control), Carrier ID (CID) compliance and Dual channel support for ASI & IP or two ASI data transmissions. All of these options work with both DVB-S2 and SatExpander SATX-2 configurations.
When you upgrade to SatExpander SATX-2 transmission technology, the SE300X typically boosts spectral efficiency by 40% to 60% compared with DVB-S2 equipment. SatExpander SATX-2 also adds superior resilience to jamming, interference, phase noise and weather fluctuations. For additional savings in operational costs, add optional SatExpander DUET CeC to double the bandwidth available on a single carrier. These and other unique technologies give the low-cost, high performance SatExpander SE300X Professional Satellite Modem the highest performance and most compelling ROI for businesses with satellite data transmission needs.
Low-Data Rate Broadcast and Data
The SE300X modem includes built-in IP processing features to make data transmission more efficient and cost-effective. The SatExpander SE300X supports point-to-point and point-to- multipoint links and incorporates the SatExpander high- efficiency NSPETM encapsulation scheme. The SE300X integrated IP processing unit supports a wide range of features such as advanced QoS, transparent bridging (Layer 2), VLAN switching (Layer 2),routing mode (Layer 3) and header and payload acceleration.
Equipped for data transmission, the SE300X comes with 4 E1/T1 interfaces for cellular backhaul, 2 ASI interfaces for video and Gigabit 1000Base-T. It also has built-in hardware support for LDPC advanced FEC. SatExpander DUET CeC (carrier-echo-cancellation). All this makes the SE300X 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 units.
