Los Angeles, CA – March 13, 2017– The Quad Small Form Factor Pluggable Double Density (QSFP-DD) Multi Source Agreement (MSA) group has released a specification for the new QSFP-DD form factor. In total, 52 companies came together in support of the QSFP-DD MSA to address the industry ...
在四激光器设计中,我们添加了一个“变速箱”,将8x 50G PAM4电气转换为4x 100G PAM4。QSFP56-DD由 QSFP-DD MSA联盟 (www.qsfp-dd.com) 定义,而OSFP由OSFP MSA组 (www.osfpmsa.org) 定义。这两种外形尺寸相似,但有三个主要区别: l OSFP允许的功率(< 15W*) 比QSFP-DD (<12W*)更大。OSFP允许早期采...

400G光模块是光通信行业的主流产品。QSFP-DD是最常用的400G光模块产品封装。本文介绍了QSFP-DD光模块常见类型SR8、DR4、FR4、FR8、LR4、LR8、ER4、ER8和ZR,分析了各型号之间的区别和应用场景并对QSFP-DD与QSFP112及OSFP光模块进行了对比。 1. 400G QSFP-DD光模块概述 ...
cage connector system. Often the one-high system is included in the initial MSA specification and the two-high is left to independent individual suppliers. To serve better the industry, the QSFP-DD MSA group chose to develop concurrently both the one-high and the two-high cage-connector ...
The MSA QSFP-DD HW Specification supports up to 400Gbps in aggregate over an 8 x 50Gbps electrical interface. The CMIS supports multiple interface settings and speed negotiation controls and allows support for multiple ‘Data Paths’ where each ‘Data Path’ consists of a sub-group of lanes to...
announced the release of an updated Common Management Interface Specification (CMIS) revision 4.0 for the QSFP-DD form factor. To continue to address the evolving industry needs for an improved high-density, high-speed networking solution, 65 companies came together in support of the QSFP-DD MSA...
The QSFP-DD800 MSA is focused on the next generation of the QSFP family of modules. The new QSFP-DD800 1.0 specification is intended to be incremental to the existing QSFP-DD 5.0 specification. As signal integrity and thermal performance remain imperative, the transceiver pads have been optimize...
