USA: Pulse Electronics Corp. has introduced a central office (CO) VDSL2 splitter module with optional lightning and power fault protection.
The module is designed with six pins, instead of the standard four pins. This enables a protective device, such as a sidactor, to be added on the board underneath the module and eliminates the need for a separate protection rack card, freeing up space for an extra multichannel card or to increase airflow for additional cooling.
The pin location allows a fast-acting secondary over-voltage protector to be used to protect the filter from surge effects while maintaining good VDSL2 performance. The location may also help to meet ITU and Telcordia coordination requirements with any installed primary protectors, enabling selection of suitable secondary protectors to accommodate different countries and markets.
Pulse Electronics’ B8841PNL CO module is part of a family of products that have the same 6 pin footprint, so modules can be interchanged to address a specific target market without changing the rack cabinet connectivity.
This pin configuration accommodates all global standards and is well-suited for use in the Americas, Europe, and Asia. It meets requirements for ETSI 600 ohm ADSL to VDSL2 applications and China YD/T 1187-2006 ADSL 600 ohms. The modules are used on a rack card in a DSLAM or within roadside cabinets to combine or split the POTS from DSL data.
