Molex and Samtec are the only suppliers licensed to offer the Molex BiPass(TM) and Samtec Twinax
Flyover(TM) Systems to meet the needs of the growing number of high-speed applications required as data centers evolve with hyperscale models and increased virtualization.
Each connection requires a twinax
cable with a differential pair configuration, so many mating cabled headers and receptacles may be necessary along the edge of a daughter card.
(1) In addition, Molex reported that it highlighted its NearStack high-speed connector system and cable jumper assemblies (Figure 2), which use twinax
cables to deliver a PCB alternative with superior signal integrity and low insertion loss while enabling implementation of 56 Gb/s NRZ and a path to 112 Gb/s PAM4.
A case study reported by  discusses about improving FedEx data centre by upgrading their network cards to 10Gb Ethernet and their existing network cables to Direct Attach Twinax
cabling, which only had 7 meters of length.
Users may also select cost-effective Twinax
direct-attach copper cables for connections up to 10 meters (sold separately).
- Combining QSFP+, Impel or near-ASIC connectors with thin Twinax
cables, BiPass I/O and Backplane Cable Assemblies provide a low-insertion-loss alternative to PCB traces for high bandwidth speeds, efficiency and proper thermal management for densely packed circuits.
TECHNIQUES RANGE PROPERTIES SDN 100 GBITS with 32 ports We use twinax
copper pair, compared to QSFP+DAC cabling.
'Wire and Cable Arabia 2015' is showcasing coaxial cables, communications cables, direct-buried cables, flexible cables, heliax cables, non-metallic sheathed cables, metallic sheathed cable, multicore cables, paired cables, ribbon cables, shielded cables, submersible cables, twinax
cables, plus many other types of wires.
In a bit to combat vendor lock-in, Siemon yesterday launched new SFP+ copper twinax
direct-attach cables (DACs) programmed specifically to work with Cisco gear featuring 10GBASE-CX1 ports.
* The ability to mate with standard 1.60 mm (.062") thick cards, as well as Samtec's AcceleRate twinax
cable assembly (ECDP Series) for a cable-to-board solution.
The CX4 interface supports Twinax
copper cabling for run lengths up to15m.
