TE Connectivity's second generation of Paralight QSFP+ was designed with internally terminated
optics and eliminates the need to clean an optical connector. The cables'
passively cooled, environmentally-friendly design have a low thermal resistance
path from the chip to the connector shell. The Paralight QSFP+ active optical
cables have a lightweight design, diameter of 3.0 mm and tight bend radius.
This second generation of cables includes
four transmit and four receive channels at 10 Gbps per channel for InfiniBand
standard SDR, DDR and QDR applications. With 850 nm VCSEL technology, the cable
assemblies operate over a data rate of 2.5 to 10 Gbps per lane with an
aggregate data rate of 40 Gbps. The cables incorporate electrical-optical and
optical-electrical conversion that is built into the connector shell for
improvement in PCB real estate utilization.
The cable assemblies are available in
lengths up to 100 m using 50 micron fiber, longer lengths are available upon
request. The EOE circuitry is designed for use with 8B/10B encoded data streams
such as InfiniBand, Fibre Channel and XAUI. The QSFP connector style supports
connections for an I2C-serial interface, which can be used to identify the
product and performance capabilities.
Product applications include high-speed
interconnects within and between switches and transport equipment,
server-server clusters, super-computing interconnections, and rack-to-rack,
shelf-to-shelf, board-to-board and board-to-optical backplane interconnections.
The active optical cables meet the differential I/O per InifiniBand version
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
