xDSL Low-Pass, High-Density Splitter/Filter Modules for VDSL2 Applications

(Product News, 2 Nov 2006)

Pulse has introduced the first in a series of SmartER xDSL high-density, low-pass splitter/filter modules suitable for very-high-bit-rate digital subscriber line (VDSL2) applications. The B8849NL is designed for European Telecommunications Standards Institute (ETSI) option A complex impedance applications. It measures 17 mm × 13 mm, and handles frequencies of 30 MHz. The SmartER modules are made with passive discrete components and a patented core material. They are used in telco central offices (CO) to achieve desireable voice quality by separating voice and data signals and filtering interference out of the data signals in xDSL applications, including VDSL2. SmartER modules can be used in two network architectures. One delivers signals to the home in the traditional manner, from CO splitter boards via copper wire. The second delivers the signals from splitter boards in nearby street cabinets, such as those used in fiber to the cabinet (FTTC) applications.
