Ports 25, 29, 33, and 37 support the following types of transceivers and
cables:
100Gbps QSFP28 transceivers

40Gbps QSFP+ transceivers

40Gbps to 10Gbps breakout cables

The ports support the following 100Gbps QSFP28 transceivers:
QSFP28SR4 transceiver - Maximum operating distance of 70m

(230 ft) or 100m (328 ft) with 12-strand OM3 or OM4 fiber optic
cable, respectively. Requires an MPO pluggable optical connector.
QSFP28LR4 transceiver - Operating range of 2m (6.6 ft) to 10km

(6.2 mi) with single-mode fiber optic cable. Requires a duplex LC
connector.
QSFP28-1CU and QSFP28-3CU direct attach cables - Lengths of

one and three meters, respectively.
The ports support the following 40Gbps QSFP+ transceivers:
QSFPSR4 transceiver - Maximum operating distance of 150m

(492 ft) with 12-strand OM4 fiber optic cable.
QSFPLR4 transceiver - Maximum operating distance of 2m (6.6 ft)

to 10km (6.2 mi) with single-mode fiber optic cable.
QSFP1CU and QSFP3CU direct attach cables - Lengths of 1 and

3 meters, respectively.
The ports also support copper and fiber optic break-out cables. The cables
convert the ports from single 40Gbps ports to four SFP+ 10Gbps ports.
The model names of the copper cables are QSFP-4SFP10G-3CU and
QSFP-4SFP10G-5CU. They come in lengths of 3 and 5 meters,
respectively. Refer to Figure 5.
