Revision 1.8 October 4, 2018
Secretariat: SFF TA TWG
Abstract: This specification defines the contact pads, the electrical, power
supply, ESD and thermal characteristics of the pluggable QSFP+ module or cable
plug.
There are multiple generations of QSFP+ that reference this specification:
SFF-8635 QSFP+ 4X 10 Gb/s Pluggable Transceiver Solution (QSFP10)
SFF-8685 QSFP+ 4X 14 Gb/s Pluggable Transceiver Solution (QSFP14)
SFF-8665 QSFP+ 4X 28 Gb/s Pluggable Transceiver Solution (QSFP+)
This specification supersedes the base electrical content of SFF-8436 QSFP+ 10Gb/s
4X Pluggable Transceiver.
This document provides a common specification for systems manufacturers, system
integrators, and suppliers.
