QSFP+ Optical Transceivers for Ethernet Apps

Tyco Electronics has launched highly compact 40Gbps QSFP+ optical transceivers, for use in switches, routers, data centres and other Ethernet applications. The parallel-fibre optical modules have four independent optical transmit and receive channels for increased board density. This extension to TE's QSFP product portfolio for the broad Ethernet and Infiniband standards marketplace combines the high-density and low-power benefits of parallel modules with some of the key advantages normally associated with SFP+-based modules, such as digital diagnostic monitoring for improved systems management.

They provide more than a 60 per cent increase in faceplate PCB density and simplify heat management through reduced power consumption (power dissipation of 0.8W) of more than 50 per cent compared with the use of four individual SFP+ modules. Offering a digital diagnostic monitoring interface, the transceivers allow customers to easily manage and monitor key module parameters of a system through alarm and warning flags for module performance.

QSFP+ MSA- and SFF-8436-compatible, the transceivers are electrically hot-pluggable, allowing for port population on demand and in the field. The latch mechanism eases insertion into board-mounted cages and optical connectivity is enabled via industry-standard MPO/MTP-terminated fibre ribbon. The QSFP+ optical transceivers will be part of a live interoperability industry demonstration at the Ethernet Alliance booth at OFC/NFOEC 2011.

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.
