Spacecom, Comtech Telecommunications Demonstrate 1.3 Gigabit C-band Link

Spacecom (Tel Aviv Stock Exchange: SCC), operator of the AMOS satellite fleet, and Comtech Telecommunications Corp. (NASDAQ: CMTL) have 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 company said.

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 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.

Spacecom (Space-Communication Ltd.) provides high-quality broadcast and communication services to Europe, the Middle East, Africa, and Asia via direct-to-home (DTH) operators, Internet service providers (ISPs), telecom and MNO operators, network integrators and government agencies. AMOS-17 further expands Spacecom´s reach in Africa and Asia, reinforcing its position as a multi-regional satellite operator.

Comtech EF Data Corp., a subsidiary within Comtech Telecommunications Corp.´s (NASDAQ: CMTL) Commercial Solutions segment, is a supplier of communications equipment with a focus on satellite bandwidth efficiency and link optimization. For more information, visit
