    Spacecom and Comtech Telecommunications Corp. Demonstrate 1.3 Gigabit C-band Link over AMOS-17 Using Comtech EF Data Modems with Telemedia South Africa


    TEL AVIV and MELVILLE, N.Y. –  May 12, 2020 Spacecom (Tel Aviv Stock Exchange: SCC), operator of the AMOS satellite fleet, and Comtech Telecommunications Corp. (NASDAQ: CMTL) today announced the successful demonstration of a 1.3 Gbps link using Comtech EF Data’s CDM-760 Advanced High-Speed Trunking and Broadcast Modems operating over AMOS-17 C-band HTS payload. The exceptionally high throughput of 1.3 Gbps on a single link was established between two Telemedia facilities over AMOS-17’s C-band spot beam using a single CDM-760 modem per facility. Telemedia is a leading provider of broadcast and teleport services in South Africa.

    In addition, using the DoubleTalk® Carrier-in-Carrier® adaptive cancellation functionality of the CDM-760, the team established a symmetrical 270Mbps/270Mbps link between two Telemedia sites using a total of only 62.8MHz on AMOS-17, achieving spectral efficiencies of 8.6 bits/Hz in such a high capacity C-band link.

    Ping tests showed that these links had a round-trip delay of less than 500ms, including the satellite link, modems and external routers, which is extremely low latency for a GEO satellite link.

    According to Eran Shapiro, Director of Business and Technology Ventures at Spacecom, “We were thrilled to partner with Comtech EF Data and Telemedia to demonstrate the very high throughput customers can enjoy on AMOS-17 C-band spot beams, without having to compromise on service availability or on solution complexity. The throughput and efficiencies of AMOS-17’s spot beams are unique over Sub Saharan Africa. Comtech EF Data’s modems and team proved this, while only using one modem per site. Engaging the African market with key enabling connectivity technologies for commercial and government sectors is a strategic goal for Spacecom. Together with Comtech EF Data, we are able to address important market segments with cost-effective, easy to deploy and maintain solutions.”

    Mark Toppenberg, President of the Commercial Group at Comtech EF Data stated, “It is exciting to see the AMOS-17 satellite performance that fully utilizes the functionality, horsepower and efficiency of Comtech EF Data’s high-performance satellite modems. Customers will really benefit from the high data rates that can be achieved even with small antennas. The combination of HTS throughput, C-band reliability and low latency makes the solution ideal for IP trunking, mobile backhaul, critical applications and remote enterprise offices.”
