SFP+ and QSFP+ systems deliver high speed performance
May 02, 2012 // Jean-Pierre Joosting
Samtec has expanded its high speed panel and I/O interfaces to include Eye Speed® SFP+ passive cable assemblies and QSFP+ active optical cable assemblies. Both systems are designed to meet various standards and protocols for high speed performance ideal in telecommunication, data communication and storage area network applications.
The Eye Speed® SFP+ passive cable assembly (SFPE Series) is compliant to SFP+ standards, and features a compact design with one channel (2 pair) transmitting up to 10 Gbps (5 GHz) on up to 3 meters of 32 AWG twinax copper cable, which reduces weight, increases airflow and provides greater port density within the rack. The cable assembly is hot swappable and backward compliant with standard SFP, making it a cost-effective solution for system maintenance and upgrades. Additionally, this assembly supports various communication standards such as Gigabit Ethernet and Fibre Channel. A right angle connector (MECT Series) and cage (SFPC Series) complete the assembly, and are available together as a kit (SFPK Series) with excellent EMI grounding and shielding.
The QSFP+ active optical cable assembly (QSFPO Series) meets QSFP MSA form-factor specifications and is included in the InfiniBand Trade Association (IBTA) Integrators’ List as being tested and accepted by IBTA with compliance to InfiniBand architecture. The lightweight cable assembly features a small 3-mm diameter optical cable for increased airflow in a rack and a tighter bend radius with cable lengths up to 100 meters. The optical engine embedded inside the cable connector converts electrical signal to optical with four channels (8 pairs) transmitting an aggregate bandwidth of up to 56 Gbps. Samtec’s unique fiber termination method allows for custom lengths, breakout cables with standard fiber connectors and best in class lead times. Additionally, the cable assembly supports Ethernet protocols and requires a low power consumption of 750 mW. This is less than half the power requirements of cables offered from competitors. A right angle connector (QSFP8 Series) and cage (QSFPC Series) complete the active optical assembly, and are available together as a kit (QSFPK Series).

Internet of Things (IoT) manufacturer Ciseco has launched the Raspberry Pi ‘Wireless Inventors Kit’ (RasWIK), featuring 88 pieces to provide everything a Pi owner needs to follow a series of step-by-step projects or to create their own wireless devices, without the need for configuration or even writing code.
RasWIK has been designed to be highly accessible, demystifying the dark art of wireless and enabling anyone with basic computing skills to begin building wireless devices with a Raspberry Pi. You can create anything from a simple traffic light, to a battery monitor, or even a temperature gauge that sends data to the Xively IoT cloud so billions can access the data.This month, Ciseco is giving away twelve Raspberry Pi Wireless Inventors kits, worth £49.99 each for EETimes Europe's readers to win.
And the winners are...
In our previous reader offer, Farsens was giving away five kits for EEtimes Europe readers to evaluate its FenixVortex, Kineo and X1 wireless, battery free sensor tags.
Lucky winners include Mr A. Neil from the UK, Mr. E. Delvaux from Belgium, Mr Lengal from the Czech Republic, Mr H. Bijlsma from the Netherlands, and Mr G. Pfaff from Germany. All should be receiving their packages soon. Lets wish them some interesting findings with their projects.
