, callout 19]
The VCU128 board hosts four QSFP28 small form-factor pluggable (28 Gb/s QSFP+) connectors:
QSFP1 J42, QSFP2 J39, QSFP3 J35, and QSFP4 J32, which accept 28 Gb/s QSFP+ optical
modules. The four connectors are housed within a single 1x4 ganged 28 Gb/s QSFP+ cage
assembly J37. The following figure shows a typical implementation of the 28 Gb/s QSFP28
module connector circuitry.
