100G QSFP28 Modules
Figure 6-12 Schematic Diagram for Installing the QSFP28 AOC Cable
2.After installing the plug of the cable module, connect the cable to the Ethernet network, and the switch port indicator
“LINK/ACT” will be on; otherwise, check that the connector of the cable is correctly connected;
Precautions during installing:
The QSFP28 connector at the end of the cable cannot be inserted backwards, if it is inserted in one direction and
cannot be inserted in the end or forced to be pushed in, please change the direction of installation to verify.
In the process of installing cable module, please do not directly touch the connecting finger part on the top of the
module by hand.
Please do not crush, bend, fold fiber or overbend the cable, otherwise it may lead to reduced system performance or
loss of transmitted data.
After installing the cable interface, please make sure that the bending radius of the cable wiring is greater
than five times of outside diameter of the cable. Otherwise, the core wires within the cable may be pulled too much,
causing damage of the cable. Assume that the outside diameter of the cable is 7.4 mm, and then the minimum
bending radius is 35 mm, as shown in Figure 6-13.
