FCI, a leading supplier of connectors and interconnect systems, has developed a low-profile subscriber interface for very-high-bit-rate Digital Subscriber Loop (vDSL) applications. The Low-Profile Subscriber Input-Output (I/O) System is a fully developed line of cable connectors, printed circuit board (PCB) connectors and cable assemblies that support the connection of signals and power for DSL subscriber accounts. The system uses separate power and signal connectors and cables to conserve space in three dimensions while providing the optimal electrical and mechanical performance required for this special vDSL application, but is also suitable for aDSL access networks and wireless base stations.

“The compact mechanical design conserves printed circuit board real estate and fits perfectly into systems with daughter cards arranged on 20mm card slot pitch, making the Low Profile Subscriber I/O System ideal for space-constrained applications,” said Rob Poort, Global Communications Market Manager, FCI.

The dual-row signal connectors have 24 contacts on 2.00mm pitch, so the PCB header uses minimal real estate (16mm deep x 33mm long x 13mm high). Custom pin assignments are available to achieve very low cross-talk performance of <-55 dB.

The power connectors have two contacts on 2.54mm pitch and the PCB header measures 20mm deep x 14mm long x 13mm high [...]
