- Q:HOW IMPORTANT IS BACKWARDS COMPATIBILITY?
A:Backwards compatibility is critically important to the industry. Since ASICs are designed to support multiple interface rates, it is critically important that the system can take advantage of thi...
- Q:WHY IS IT CALLED ˇ°DOUBLE-DENSITYˇ± WHEN IT APPEARS TO QUADRUPLE THE PORT SPEED COMPARED TO QSFP28?
A:The term ˇ°Double-Densityˇ± refers to the doubling of the number of high-speed electrical interfaces that the module supports compared to the regular QSFP28 module. The connector specification is...
- Q:WHAT WILL THE MECHANICAL INTERFACE LOOK LIKE; CAN I PLUG A CURRENT QSFP INTO THE NEW CONNECTOR/CAGE?
A:The mechanical interface for QSFP-DD on the host board will be slightly deeper than for QSFP28 to accommodate the extra row of contacts. The height and width will be identical to the QSFP form fa...
- Q:IS THE QSFP-DD MSA DEPENDENT ON OTHER OUTSIDE STANDARDS ACTIVITY?
A:As is usual with MSA specifications for module form factors, many other standards specifications are used for the electrical and optical interfaces. QSFP-DD will support both CAUI-4 and 400GAUI-8...
