28 Gb/s zQSFP+ Module Connectors
[Figure 2, 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+ opcal
modules. The four connectors are housed within a single 1x4 ganged 28 Gb/s QSFP+ cage
assembly J37. The following gure shows a typical implementaon of the 28 Gb/s QSFP28
module connector circuitry.
Table 12 through Table 15 in Right-side GTY Transceiver Connecvity list the QSFP28
connecons to the XCVU37P FPGA U1 MGTY transceiver banks 135 (QSFP1), 134 (QSFP2), 132
(QSFP3), and 131 (QSFP4).
