Cable I/O - Cable Assemblies
The MicroGigaCN offers a cost-effective I/O
solution for high-speed applications in data and
telecommunications convergence (voice, data, video
and storage). It utilizes a 2.5 Gbit/sec wire speed
connection with four or twelve wire link widths, offering
a scalable performance range of 500Mbps to 6Gbps
per link to meet the needs of entry-level and high-end
enterprise systems. Forward crosstalk is less than 4%
at 100 pico second pulse-rise time (four-pair
switching).
Fujitsu Components designed the MicroGiGaCN to
specifically address the emerging requirements for a
Electrical Performance in out testing:
high speed differential signal I/O connector. The
MicroGiGaCN offers a unique solution to LVDS,
InfiniBand TA, 10G Ethernet, 4x Fiber Channel, and
other high speed I/O applications. InfiniBand has
selected Fujitsu’s connector for the 4x and 12x I/O
connector interface.
The performance requirements of the
connector system were tested with cable to simulate
the actual requirements of an OEM System
manufacturer. Our test data includes the parasitic
effects of the PCB, along with measurements of a
completed I/O cable assembly.
