QSFP vs. SFP: What’s the difference between QSFP and SFP?
The Quad Small Form-factor Pluggable (QSFP) is a compact, hot-pluggable transceiver used for data communications applications. It is an industry format jointly developed and supported by many network component vendors, allowing data rates from 4x1 Gb/s for QSFP and 4x10 Gbit/s for QSFP+ and to the highest rate of 4x28 Gbit/s known as QSFP28 used for 100 Gbit/s links.
The difference between QSFP and SFP is mainly in data rates. As shown in the table
QSFP | SFP | |
Data rates | 4 x 1 Gbit/s QSFP 4 x 10 Gbit/s QSFP+ 4 x 14 Gbit/s QSFP+ (QSFP14) 4 x 28 Gbit/s QSFP+ (QSFP28) | 1 and 2.5 Gbit/s SFP 10 Gbit/s SFP+ 25 Gbit/s SFP28 |
QSFP vs. SFP
QSFP stands for 4 channels of SFP traffic.
Allowing data rates is difference.
