July, 2011 Pulse Intros First CO Splitter Module
San Diego, CA — New from Pulse Electronics Corporation is the first dual central office VDSL2 splitter module. The B8891DVNL combines two central office (CO) splitter mod- ules onto one platform. This compact configuration increases available PCB space by 40 percent while reduc- ing the component count, resulting in new possibilities for high density board applications. Now designers can increase the
number of channels, potentially increasing a 24-channel CO splitter board to a 48-channel board, while maintaining the same printed circuit board dimensions, or conversely can get the same functionality from a much smaller circuit board. According to the company, the
Load splitter module.
dual central office splitter module is the first of its kind. Because of its compact size, this product offers the
advantage of potentially doubling the number of channels on a central office splitter board without the cus-
tomer having to change the physical form factor of the board. The dual nature of the B8891DVNL enables it to be used in high density central office VDSL2 applications. The dual CO splitter module is
used on a rack card in a DSLAM or within roadside cabinets to combine or split the POTS (plain old tele- phone service) from DSL (digital sub- scriber line) data. The module is com- pliant to China MII YD/T 1187-2006 ADSL2+ and VDSL2 600 ohm appli- cations. It is RoHS-6 compliant and TR-127 compliant for ADSL2 and VDSL2 applications. Contact: Pulse Electronics

New Hipot Tester from Quadtech to 500 VA
Marlborough, MA — QuadTech has released the new Guardian 500VA Plus, which replaces the original Guardian 500VA in the hipot tester product family. The new Hipot Analyzer is designed for applications requiring a 500VA output trans- former capacity with 100mA AC out- put current and 200mA short circuit current. The 500VA Plus can be used for applications requiring variable hipot frequency from 50Hz to 600Hz. The analyzer has both hipot test and breakdown analysis modes, making the unit flexible for both production and R&D applications. The instrument is suitable for

testing to standards that require a 500VA output transformer, variable frequency hipot or 200mA short cir- cuit current, such as: ASTM D149- 09, IEC 60934 and IEC 60335-1. Its R&D functions include arc detection monitoring, output for connection to an oscilloscope, and breakdown volt mode. Breakdown volt mode is a new function that will increase the volt- age in steps and dwell at each volt- age step per the programmed time delay. The unit also has the ability to measure total and real current. The tester is equipped with a new func- tion called High Frequency Contact Check (HFCC) — a new measure- ment technology for contact check. It can be performed during the hipot test using a high frequency, around 1MHz, for improved test time on the production line. The Guardian 500VA Plus has a
large LCD screen for programming and measurement. Ground fault inter ruption and floating output fea- tures can also be used for operator protection. The hipot tester is equip - ped with an output to monitor the arc signal with an oscilloscope. The remote command set provides SCPI commands for both control and meas- urement. This unit comes standard with RS-232 and USB interfaces. Contact: QuadTech, Inc.,
