High Speed, Serial I/O, Cable Assemblies

Product Bulletin No. 10-25-03

Meritec is now offering a new line of cable
assemblies to support InfiniBand™ (IB)
architecture specifications and other industry
standards for high-speed data transfer
applications to include 10G Fibre Channel,

12X Straight

All Shown with

Optional

“Pull-to-Release”

Latch Actuator

4X Straight

4X Angled

Serial ATA (SATA), and Serial Attached SCSI
(SAS), 10G Ethernet, and CX4.

Meritec’s new offering is designed to support
channel-based switched fabric I/O technology
and industry standards for continuous flow
“serial” link computing. The assembly
provides for the continuous uninterrupted flow
of serial data.

Meritec’s Direct Attach 4X** cable assembly meets IB™ standards by allowing for high-speed data rate
transfers of >2.5Gbps per each link/channel at lengths up to 8.5 meters 24 AWG not equalized and meets
CX4 standards up to 16 meters. Direct attach methodology offers cross-talk performance of <1.0%* which
has been difficult to achieve in 4X designs utilizing internal printed circuit boards for wire termination.
Greater bandwidth and exceptional overall electrical performance are also favorable byproducts of the
design.

Meritec’s Direct Attach 12X*** cable assembly meets IB™ standards by allowing for high-speed data rate
transfers of >2.5Gbps per each link/channel at lengths up to 8.5 meters 24 AWG not equalized and meets
CX4 standards up to 16 meters. Direct attach methodology offers cross-talk performance of <1.0%* which
has been difficult to achieve in 12X designs utilizing internal printed circuit boards for wire termination.
Greater bandwidth and exceptional overall electrical performance are also favorable byproducts of the
design. The use of three lengths of 4X cable provides greater flexibility than does one bundled 12X cable.

Passive Equalization - Both Meritec’s Direct Attach 4X and Direct Attach 12X are offered with passive
equalization circuits built into the connectors back-shells to achieve higher data rate transfers (>2.5Gbps)
and/or longer cable assembly lengths (equalized IB™ 12.5 meters, 24 AWG).

The connector interface utilized in the Direct Attach series of cable assemblies has been selected by the
various standards organizations responsible for InfiniBand™, 10G Fiber Channel, SATA, Serial Attached
SCSI (SAS) and 10G Ethernet.

* <1% nearest neighbor and <2% multiple aggressors
** 4X is 10Gbps bi-directional typically usable data rate transfer.
*** 12X is 30Gbps bi-directional typically usable data rate transfer.
