QSFP+ Quad Small Form Factor Pluggable Plus 40 Gbps Interconnect System Data-transmission speeds are continuing to rise as consumers demand ever higher performance from a variety of communications

2 QSFP+ Quad Small Form Factor Pluggable Plus 40 Gbps Interconnect System Data-transmission speeds are continuing to rise as consumers demand ever higher performance from a variety of communications devices. New trends, like cloud computing or Internet-based computing, where there is a need for seamless access to large data centers, are driving significant growth in bandwidth requirements. LOROM s unique offering of precision external QSFP+ cable assembly solutions provides a complete product platform addressing and providing unique value propositions to these difficult challenges. The QSFP+ cable assembly product platform provides a cost-effective, high-speed solution that meets and exceeds the bandwidth requirements of current and future applications in servers and external storage systems. This unique product offering exceeds the performance requirements specified by SFF-8436, 10 G Ethernet IEEE 802.3ba, Fibre Channel, InfiniBand QDR, SAS and SONET/SDH standards with different data rate options. 2

3 E-MAXX Future Cable Technology LOROM QSFP+ Cable Assemblies Include Unique World- Class, State-of-the-Art, in House Developed E-MAXX Bulk Cable, Providing the Highest Level of Signal Integrity Performance. E-MAXX provides extremely low-insertion loss due to our unique skinfoam skin, gas-injected dielectric technology as well as extreme control of balanced/unbalanced (Mode conversion). This ensures significant performance advantages in increased system head-room/budget, as well as ease of cable management and smaller packaging densities. The cable assemblies employ new, innovative PCB technology designed specifically to address the complex issues of optimizing signal integrity performance. The cables regulate cross talk and launch conditions between wire and PCB termination to optimize return loss and prevent or minimize ringing effects. Our highly automated, controlled cable assembly manufacturing processes using the world s first automatic soldering process, optimizes the critical termination between wire and PCB, improving overall performance and removing the human element. Automated final-test and quality systems assure high-quality cable assemblies, conforming to the high-speed electrical performance requirements in industry specifications. Our commitment to excellence ensures that the mechanical design exceeds the stringent mechanical interface requirements as defined by applicable industry standards. 3
