Subscriber Interface targets vDSL applications.

Press Release Summary:

Composed of cable connectors, pcb connectors, and cable assemblies, Low-Profile Subscriber I/O System supports connection of signals and power for DSL subscriber accounts. Dual row signal connectors have 24 contacts on 2.00 mm pitch, power connectors have 2 contacts on 2.54 mm pitch, and pcb header measures 14 x 20 x 13 mm. Cable connector design employs 2 additional first-mate/last-break sacrificial contacts to prevent arcing to primary power contacts.

FCI Develops High-Density, Cost-Effective Subscriber Interface for VDSL Applications

(ETTERS, PA-June 11, 2007) 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. The cable connector design employs two additional first-mate/last-break (FMLB) sacrificial contacts to prevent arcing to the primary power contacts while enabling "hot" mating.

Dual-metal PV® power contacts and dual-beam signal contacts provide durable and reliable electrical connections. Polarized connector designs prevent mis-mating during connector engagement, and integral screw hardware fastens connectors together to prevent accidental un-mating.

The RoHS-compatible interface is available in component kits or as custom cable assemblies.

Prices for the Low-Profile Subscriber Input-Output System start at $0.30 per mated signal contact. Production lead-times are 6 weeks.
