Pulse Electronics intros first surface mount central office splitter module

SAN DIEGO, USA: Pulse Electronics Corp., a leading provider of electronic components, has introduced the first surface mount (SMT) central office (CO) splitter module.

The B89S59NL is used on a rack card in a digital subscriber line access multiplexer (DSLAM) or within roadside cabinets to combine or split separate plain old telephone service (POTS) and DSL data signals.

Pulse Electronics’ module is the first CO splitter module in a surface mount, rather than through-hole, configuration, which offers many advantages. SMT technology provides improved shock and vibration resistance as a result of the shorter lead lengths. Manufacturing benefits include reduced board and material handling costs.

The SMT soldering process can be automated for high volume manufacturing to expedite and increase production and reduce labor and handling. Placement of SMT modules is more reliable than placing through-hole modules or hand soldering because when the heated soldering sheet becomes molten, the natural surface tension it creates pulls the components into their exact proper positions.

“This product is the only surface mount central office splitter module on the market today,” said Ronan Kelly, product marketing engineer for Pulse Electronics.

“SMT PCBs are much stronger and resistant to external stress than their through-hole counterparts. When an electronic device is dropped or shaken, if the components have been surface-mounted, the electrical connection is much more likely to remain intact. The higher quality product accompanied by the manufacturing advantages will definitely improve the options for companies that design and manufacture central office equipment.”

The B89S59NL has the same footprint as Pulse Electronics’ SmartER range of central office splitter modules. The SmartER splitters have a unique footprint that allows modules that comply with the numerous different global standards to be interchanged without having to redesign the splitter board at the customer. This enables the customer to address different markets using the same footprint, but populating it with different modules to suit a particular standard.

As with other Pulse Electronics products, the B89S59NL uses Pulse Electronics’ patented technology that allows for better performance, increased compactness, and high quality construction. The product is TR-127 compliant for VDSL2 applications and meets the ETSI Complex Impedance and Option A relative to metering pulse at 12 kilohertz.

TR-127 is a technical report developed by the Broadband Forum to ensure the highest quality delivery of voice, data, and video services (triple play) by maximizing the interoperability of splitters and in-line filters with DSLAMs and modems.

All SmartER modules can be manufactured in surface mount configuration if requested by the customer. The modules come in trays, but other packaging options are available. Price and availability depend on volume.
