SAS (Serial Attached SCSI) storage systems I/O interface and its data transmission rate and interconnect types are expanding again. SCSITA, the SCSI Trade Association, has been marketing, driving and supporting the next generation SAS 4.0 running at 24Gbps per lane. The Industry standards group INCITS-T10 is working with www.SFFcommittee.org on developing a new higher-speed […]
Why are backplane 24-56G cables replacing many PCBA types?
The advent of digital signaling higher frequencies and data rates at 24G SAS, 25G Ethernet, 26G InfinBand and 28G FibreChannel have caused the need to evaluate and develop alternative media types versus traditional FR4 PCB substrates which can no longer provide acceptable transmission performance. The exponential cost of newer improved dielectric PCB substrates, from 5x […]
What’s new in infrastructure CAT-5 and CAT-8 balanced pair connectors?
CAT-5e or Category 5 enhanced, a second generation CAT-5 infrastructure interconnect using non-shielded RJ-45 jack and plug connectors, has been a dominant 1 GbE port high volume market for several years. However its usage for LAN is past its peak as many more 10 GbE ports requiring CAT-6a or CAT-7a connectors are being shipped and […]
