High-density splitter/filter modules for VDSL2

21 February 2007 Passive Components

Pulse has introduced the first in a series of SmartER xDSL high-density, low-pass splitter/filter modules. The B8849NL series is suitable for use with very-high-bit-rate digital subscriber line (VDSL2) applications and meets the ETSI option A complex impedance applications requirements.

At 17 x 13 mm, the company says the B8849NL is one-third the size of standard B8049 SMART modules and handles frequencies of 30 MHz, compared with 2,2 MHz for the SMART modules. Pulse's SmartER series defines the new package and footprint standard for xDSL modules providing a reliable, lower-cost solution.

The SmartER modules are made with passive discrete components and a patented core material. They are used in telco central offices (CO) to separate voice and data signals and filter interference out of the data signals in xDSL applications, including VDSL2. The latest and most advanced DSL broadband wireline standard, VDSL2 is designed to support the wide deployment of triple play (voice, video, data) services such as high-definition television (HDTV), and interactive gaming.

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 fibre to the cabinet (FTTC) applications, in which the last mile of the signal travels over copper using VDSL2 technology. These SmartER modules are intended to address the challenge of carrying more channels and handling higher frequencies while fitting into street cabinets with limited space. These filters can also be used on a customer premises equipment (CPE) modem board for single-line low-pass filter solutions.
