The Latitude E6400 XFR from Dell is engineered to meet the needs of even the most demanding customers in the harshest environments. The system meets a higher drop specification and offers a greater level of dust and moisture protection than any fully rugged laptop in its class. Designed for the military, first responders, oil and gas environments, manufacturing floors, field technicians, and homeland security, the Latitude E6400 XFR features the Dell-exclusive Ballistic Armor Protection System featuring PR-481, which leverages a high-strength substance used for applications such as cryogenics, aircraft components, military equipment and medical devices. The Latitude E6400 XFR also features PrimoSeal Technology to enhance protection from dust and liquid with compression gaskets. The fully rugged laptop is engineered and independently tested to more than 13 military standards for operation in challenging environments. It shares common images and components with the Dell Latitude E6400 laptops for easy integration into existing environments and enables low ownership costs.
Multiplexer Enables Network Speed and Bandwidth
Fujitsu Network Communications, a supplier of optical and wireless networking solutions, has announced the general availability of second-generation 40 Gbps interfaces for its Flashwave 7500 reconfigurable optical add/drop multiplexer (ROADM). Utilizing an innovative adaptive differential phase shift keying modulation scheme and Fujitsu-patented Variable Dispersion Compensation, the units enable network growth up to 1.6 Tbps of capacity to help customers meet ongoing demands for increased speed and bandwidth. Three new 40 Gbps units are now available for the Flashwave 7500 ROADM, including the 40 Gbps Transponder, 4:1 Muxponder, and 40 Gbps Regenerator. Primarily intended for 40 Gbps core router interconnection services, the 40 Gbps Transponder provides a full-band tunable network interface and an OC-768 client interface. Supporting four 10 Gbps client interfaces, the 4:1 Muxponder provides an efficient method for aggregating 10 Gbps traffic and quadrupling the capacity of existing 10 Gbps-based networks. The 40 Gbps Regenerator provides electrical signal regeneration for long spans, eliminating the cost and complexity involved with the use of back-to-back transponders.

Receiver Delivers Real-time ISR Video
Harris has introduced the ISR Video Receiver, a portable product that delivers high-resolution full-motion tactical video to individual warfighters for real-time intelligence, surveillance and reconnaissance. The handheld Harris ISR receiver, known as the RF-7800T, provides a next-generation portable ground-based, remotely operated video enhanced receiver (ROVER) for video captured by the military’s growing fleet of UAVs. This is the first video receiver packaged in a standard military-hardened handheld form factor, greatly increasing both portability and survivability in demanding battlefield environments. The RF-7800T is part of an accelerated push by Harris to apply its leadership in software-defined communication systems to deliver ISR video directly to the tactical edge, where it can be viewed, analyzed and acted upon immediately. Harris previously introduced ROVER capability in its high-performance Falcon III AN/PRC-117G multiband manpack radio, targeting customers with dual needs for both ISR information and advanced multimode communications. The handheld ISR Receiver operates in the L-frequency band, and also supports both S-band and C-band. The initial release provides NTSC FM video formatted data. The device feeds video to a local display and is sold with both monocle and tablet display options.

Low-latency Solution Enables Bandwidth Efficiency
Comtech EF Data has announced the general availability of adaptive coding and modulation (ACM) for the CDM-625 Advanced Satellite Modem. The patent-pending and unique implementation of ACM is available for the CDM-625 when utilizing the next generation forward error correction VersaFEC. The combination of VersaFEC and ACM deliver significant lower latency benefits to VSAT users when compared to alternate implementations of ACM using DVB-S2. ACM turns fade margin into increased link capacity by automatically adapting the modulation type and forward error correction code rate to provide the highest possible throughput. ACM maximizes throughput regardless of link conditions. And, it can yield higher system availability even in severe rain fading conditions with lower throughput. VersaFEC was designed to provide maximum coding gain at the lowest possible latency for both constant coding and modulation and ACM operation. VersaFEC uses a constant number of symbols per frame. When compared to DVB-S2 ACM, which uses a constant number of bits per frame, the combination of VersaFEC and ACM provide a significant reduction in system latency. The new Comtech EF Data low latency ACM solution enables more bandwidth efficiency and increases throughput for IP-based point-to-point applications. ♦
