The orders specified high-speed and mid-range satellite modems, including the new CDM-625A Advanced Satellite Modem along with the CDM-625, CDM-700, DMD50 and DMD20 modems. This array of field-proven modems provides unrivaled performance teamed with the reliability required by the most demanding users around the world. This follow-on order was based upon past performance and product reliability of the many Comtech EF Data products this systems integrator has leveraged over several years to expand its business and meet the stringent demands of its end customers.

The mid-range CDM-625A and CDM-625 modems enable the cost-effective rollout of enhanced services that allows an operator to increase its subscriber base while minimizing subscriber churn. The CDM-625A leverages the multi-dimensional traffic optimization required to most intelligently and efficiently utilize space segment resources, which is key with both traditional and High Throughput Satellite (HTS) spacecraft designs. The feature set of Comtech EF Data’s high-speed satellite modem family, including the CDM-700, enables an operator to utilize low-cost, high-speed satellite-based trunking links to complement terrestrial connections. This mix of satellite and terrestrial links result in the most resilient and reliable hybrid solution possible, thereby allowing an operator to provide best service levels possible with the highest uptime.

Examples of integrated features ordered that provide trusted reliability while minimizing overall network CAPEX and OPEX are DoubleTalk^® Carrier-in-Carrier^® bandwidth compression, a Quad E1 Interface with Enhanced Drop & Insert capability along with a combination of highly powerful coding methods, namely Low Density Parity Check and Turbo Product Codes. Featuring a vast range of data rates and interfaces, support for both L-Band or 70/140 MHz connections and configurations for use on single or multiple transponders, the array of modems procured provide the flexibility needed to support both upgraded and legacy hub and remote terrestrial environments.

To complement the modems, also ordered were SFC4200A and SFC1275A Synthesized Frequency Converters along with the SEU-100 Signal Excision Unit. The high-performance converters feature redundancy, low phase noise and flexible options for monitor and control. The SEU-100 significantly enhances the performance of geolocation systems, improving location accuracy and enabling emitters to be successfully located in many situations where geolocation without signal excision is not possible.

“Comtech offers an assortment of products suited for different applications and operating environments,” commented Fred Kornberg, President and Chief Executive Officer of Comtech Telecommunications Corp. “These follow-on orders are acknowledgment of the confidence in Comtech to support mission-critical communications today and into the future.”
