Opulan Releases Broadband-Access Products

Opulan Technologies has introduced broadband-access solutions that consist of 10Gbps EPON (Ethernet passive optical networks), OpconnT and cableTV SOCs and ASSPs. The Opulan 10Gbps EPON solution has successfully passed chip-level interoperability testing organised by China Telecom. The main benchmark testing performed included - MPCP discover, register and ranging; DBA; scalable OAM; and backward compatibility with 1G EPON - the key requirements in IEEE802.3av and China Telecom specifications. Opulan's solution is FPGA based and achieved downstream data flow at 9Gbps and upstream at 950Mbps under an asymmetric model. After smooth testing, Opulan's Opconn 1G EPON SOC will commence full production. 

The Opconn is a client-side ONU SOC of an EPON solution. Opulan's engineering team has completed thorough product and interoperability testing against IEEE802.3ah and China Telecom EPON standards. The ONU SOC features an embedded MIPS4kec processor for board-level control and management; a powerful Ethernet switch and dynamic bandwidth allocation (DBA) engine that offers wire-speed processing; IEEE802.1ad and 802.1q Bridge; flow-based QoS classifier, and hardware-based AES-128/Triple churning encryption module. Opconn can work under three common scenarios. It can be an uplink for Opulan's cableTV-based EOC solution, carrying traffic from CATV broadband subscribers; it can backhaul Opulan's IPMux-based xDSL traffic aggregation; and it can be the final POP of a service provider directly connecting FTTH (fibre to the home) clients.

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.
