① 100G QSFP28 DAC direct connection: Both ends are 100G interfaces, which are suitable for stacking and direct connection between 100G devices at a short distance, for the same frame;

② 100G QSFP28 DAC connection 4*SFP28 DAC: It is suitable for 100G interfaces between 100G and 25G devices, and the other end is 4 25G interfaces, supporting the distance of 1 meter-5 meters;

③ 40G QSFP+ DAC direct connection: both ends are 40G interfaces, which are suitable for stacking and interconnection between 40G devices at a short distance, the maximum transmission distance is 7m;

④ 40G QSFP+ DAC connection 4*SFP+ DAC: It is suitable for 40G interfaces between 40G and 10G devices, and the other end is 4 10G interfaces, with a maximum transmission distance of 7m.

AOC connection solution:

① 100G QSFP AOC direct connection: Both ends are 100g interfaces, using OM3 optical fiber transmission distance of 70m, and use OM4 optical fiber to transmit 100m;

②100G QSFP28 AOC connection 4*SFP28 AOC: It is suitable for 100G interfaces at the interconnection between 100G and 25G devices, and the other end is 4 25G interfaces;

③ 40G QSFP+ AOC direct connection: both ends are 40G interfaces, transmitted with OM3 fiber, suitable for 40G device interconnection within 100M;

④ 40G QSFP+ AOC connection 4*SFP+ AOC: It is suitable for interconnection between 40G and 10G devices, transmitted with OM3 fiber, one end is 40G interface, and the other end is 4 10G interfaces.

In actual applications, 1-5M is recommended to choose DAC high-speed cables, 7-100m is recommended to use AOC active optical cables, and optical modules are recommended to connect with optical cables above 100M.
