Gennum Demonstrates 4x25Gb/s Active Copper Cables for 100Gb/s Networks

Enabling next-generation 100Gb/s networks, Gennum Corporation (TSX: GND) today announced a demonstration of active copper cables using Gennum's 25-28Gb/s CDRs at the DesignCon 2012 Exhibition, January 31 – February 1, in Santa Clara (booth #741).

The demonstration will feature Gennum's GN2425 and GN2426 module clock and data recovery (CDR) integrated circuits communicating over a 6-meter copper cable operating at 25-28Gb/s. The link is comprised of host board traces, module board traces, a Molex zQSFP+ interconnect system and a 6-meter 26 AWG copper cable. The cable alone has approximately 20dB of loss at the Nyquist data rate. Using Gennum's CDRs to transmit and receive the signal at either end of the cable, the link is able to operate at a bit-error-rate (BER) of less than 1E-15.

As global Internet traffic is expected to multiply over the coming years, significantly more bandwidth will be required, driving the need for large-scale network upgrades. Gennum's GN2425 and GN2426 are designed to support 25-28Gb/s data streams for next-generation 100Gb/s fiber-optic modules, line cards and direct-attach copper cables using emerging module form factors such as 28G-QSFP+ and CFP2. They provide exceptional jitter performance with low power consumption.

By resetting the jitter budgets within the link in both the transmit and receive directions, Gennum's CDRs enable robust operation for new systems such as 4x25G active copper cables, active optical cables and pluggable optical modules.

"Active cables offer several benefits for system designers," said Ed Frlan, Senior System Architect in Gennum's Mixed Signal & Optical Products Division. "They offer optimal reach and power while simplifying the design of the high-speed serial link between the host ASIC and the cable connector."

The live demo at the Gennum booth (booth 741) of the DesignCon 2012 Exhibition in Santa Clara demonstrates the availability of key building blocks enabling a system or equipment manufacturer to begin manufacturing higher density and lower power 100Gb/s networks.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
