SFP, SFP-DD, QSFP, QSFP-DD & OSFP Pluggable interconnects – a 2021 update

February 17, 2021 By Ed Cady Leave a Comment

pluggable interconnects

The 21-year-old Pluggable interconnect family is now being used for new accelerator, AV, camera, machine vision, medical, memory, NVM, and proprietary interface links. New market segment expansion seems likely to continue with link shipments rising and healthy unit forecasting. New higher speed 106G and 112G per lane pluggable products will be coming out this year, […]

MicroQSFP, QSFPDD,OSFP interconnect systems chosen by IEEE

April 24, 2017 By Ed Cady Leave a Comment

Just recently in Vancouver, the Ethernet IEEE-802.3cd Standards Committee voted yes simultaneously to include MicroQSFP, QSFP-DD and OSFP interconnect modules as MDI (media dependent interface) options. The remarkable singular vote, of 66 yes, 0 no, and 14 abstain, seemed to reflect the wide and deep need to support different types of new and established enterprise, […]

OSFP interconnect: what is it?

January 18, 2017 By Ed Cady Leave a Comment

OSFP interconnect

OSFP, Octal Small Formfactor Pluggable, is a very new module and interconnect system in development that is targeted to support 400-G optical data links inside datacenters, campuses and external metro long reach. The private consortium OSFP MSA group was founded by Google and is led by Arista Networks. This consortium already has more than 50 […]

New I/O standards use different lane count circuits to drive new connector use in DCs

November 23, 2016 By Ed Cady Leave a Comment

qsfp-dd-two-different-plugged-connector-ends

InfiniBand is a very high-speed server fabric I/O network with various lane counts and connector/cabling specifications. The current high volume HPC and DataCenter installations are primarily using EDR 25.7G per lane interconnects. This is done using primarily a 4-lane option cable link between ToR switch and rack leaf server using the QSFP28 connector system. Although […]

New Gen-Z Interconnect Consortium launched

November 3, 2016 By Ed Cady Leave a Comment

Gen-Z is a very new interconnect consortium that is focused on newer, advance memory, storage and accelerator architectures and devices. Gen-Z is based on the IEEE-802.3 physical layer specifications and external interconnects like SFP28 and QSFP28 connectors, cables and modules. Its first generation data transfer speed rate is 25Gbps per lane. 56GT/s and 112GT/s speed […]

What are Terapipe I/O compression connectors and cables?

September 14, 2016 By Ed Cady Leave a Comment

Terapipe prototype connectors

Terapipe I/O compression connectors and cables were developed and used in very low volume ten years ago for a special very high frequency test instrumentation network that included Vector Network Analyzer and Bit-Error-Rate Equipment. These connectors and cable assemblies had to have a very clean SI design and performance, which meant having the minimum geometry […]

Considerations for modern industrial connector plug designs

July 18, 2016 By Ed Cady Leave a Comment

datacenter-elegant

Last week, we talked about how industrial connector plug designs evolved through the 1990s, growing ever smaller and more flashy in design. More recently, these modern industrial connector plug designs have been even more miniaturized and streamlined for lightweight, simple use. For example, during the 2000s, industrial design changed dramatically. Connectors shrunk another 20-30% to mostly […]

NumaLinksupercomputer100 circuitcable and macrosized metal plugcirca 1990s

Whether you are a general consumer, professional electronics user or a datacenter support technician/engineer, the appearance and handling of connectors and cables has been and can still be a sometimes bewildering or even gnarly experience. There are many factors to consider. Let’s take a backward, current and near future look at the evolution of I/O […]

What are MPO connectors?

June 2, 2016 By Ed Cady Leave a Comment

USCONEC's MPO connectors types

MPO—Multi-fiber Push On—is a type of optical connector that has been the primary multiple fiber connector for high-speed telecom and data communications networks. It has been standardized within the IEC 61754-7 and TIA 604-5. This connector and cabling system first supported telecommunications systems especially in the Central and Branch offices. Later it became the primary […]
