Comtech EF Data


Comtech EF Data Corporation, a subsidiary of Comtech Telecommunications Corporation (NASDAQ: CMTL), is the recognized global leader in satellite bandwidth efficiency and link optimization. Our advanced communication solutions encompass Advanced VSAT Solutions, Modems, RAN & WAN Optimization, Network & Bandwidth Management, RF Products, and more. The solutions enable commercial and government users to reduce OPEX/CAPEX and to increase throughput for fixed and mobile/transportable satellite-based applications.

Products are designed and manufactured at our Tempe, Arizona USA plant. Our well-maintained facilities are configured to support current and planned production requirements. We employ formal quality management programs and training, including the International Standard Organization’s (“ISO-9000”) and Aerospace Standard (“AS9100”) quality procedure registration programs.

We are recognized as a technology innovator, and have a reputation for product quality and reliability. Examples of our technologies that optimize satellite communications are:

  • DoubleTalk® Carrier-in-Carrier® Bandwidth Compression
  • VersaFEC® Forward Error Correction
  • Adaptive Coding & Modulation
  • DVB-S2
  • Low Density Parity Check Coding (LDPC) & 8-QAM Modulation
  • 2nd Generation Turbo Product Coding
  • Integrated Router
  • Radio Access Network (RAN) Optimization
  • WAN Optimization
  • Dynamic Single Carrier per Channel
  • Daisy Chain Redundancy Switching

Our products are installed in 160+ countries. We provide “around the clock” customer support and have authorized service centers globally. We are prepared to help you optimize bandwidth, reduce OPEX/CAPEX associated with satcom, and lower the total cost of ownership.
