Overview
The CDM-425 Advanced Satellite Modem continues to build on our legacy of providing the most efficient and reliable satellite modems. It offers the most popular and powerful features of the CDM-625A, with a smaller footprint and less power. Its Forward Error Correction options comprise 18 VersaFEC® ModCods and 74 VersaFEC-2 ModCods, permitting the user to optimize for latency and coding gain for any link budget. It includes DoubleTalk Carrier-in-Carrier bandwidth compression, additional TX rolloffs and sophisticated packet processing capabilities.
This combination of advanced technologies enables multi-dimensional optimization,
allowing satellite communications users to:
• Minimize operating expenses (OPEX)
• Maximize throughput without using additional transponder resources
• Maximize availability (margin) without using additional transponder resources
• Minimize capital expenses (CAPEX) by allowing a smaller BUC/HPA and/or antenna
• Or, a combination to meet specific business needs
Features
• DoubleTalk Carrier-in-Carrier bandwidth compression
• Carrier-in-Carrier Automatic Power Control
• VersaFEC-2 High Performance LDPC with Adaptive Coding and Modulation (ACM), Short Block and Long Block – similar performance to DVB-S2X with significantly lower latency.
• VersaFEC FEC with Adaptive Coding and Modulation (ACM), both standard and Ultra-Low Latency (ULL)
• 5%, 10%, 15%, 20%, 25% and 35% Transmit Filter Rolloff
• Optional Packet Processor with header compression, payload compression, advanced Quality of Service (QoS) and Managed Switch Mode with VLAN support
• Integrated 4-port managed Ethernet switch with VLAN and QoS
• Jumbo frame support
• Dual Band Capability: 70/140 MHz and extended L-Band (950 – 2250 MHz) in same unit
• Data Rate: 18 kbps to 25 Mbps
• Symbol Rate: 18 ksps to 12.5 Msps
• Modulation: BPSK, QPSK, 8-QAM/8-ARY, 16-QAM/16-ARY, 32-ARY
• FEC: VersaFEC (low-latency LDPC) and VersaFEC-2 (high performance LDPC)
• Wide Range of data interfaces: EIA-422/530, V.35, G.703 T1/E1, Quad G.703 E1, 4-port 10/100Base-T Ethernet
• IEEE 1588v2 Precision Time Protocol
• Sub Mux to multiplex IP/Ethernet traffic with serial or G.703 traffic
• Drop & insert for T1/E1
• Enhanced D&I++ for single T1/E1 & quad E1
• Management: 10/100Base-T Ethernet with SNMP, Distant
