DAC cable connection solution:
① 100G QSFP28 DAC direct connection: Both ends have 100G interfaces, suitable for stacking and direct connection between short distance 100G devices, used in the same rack;
② 100G QSFP28 DAC connection 4 * SFP28 DAC: suitable for interconnection between 100G and 25G devices, with one end having a 100G interface and the other end having four 25G interfaces, supporting a distance range of 1-5 meters;
③ 40G QSFP+DAC direct connection: Both ends have 40G interfaces, suitable for stacking and interconnection between short distance 40G devices, with a maximum transmission distance of 7M;
④ 40G QSFP+DAC connection 4 * SFP+DAC: suitable for interconnection between 40G and 10G devices, with one end having a 40G interface and the other end having four 10G interfaces, with a maximum transmission distance of up to 7M.
AOC cable connection solution:
① 100G QSFP AOC direct connection: interfaces with 100G on both ends, using OM3 fiber optic transmission distance of 70m, and OM4 fiber optic transmission distance of 100m;
② 100G QSFP28 AOC connection 4 * SFP28 AOC: suitable for interconnection between 100G and 25G devices, with one end having a 100G interface and the other end having four 25G interfaces;
③ 40G QSFP+AOC direct connection: both ends are 40G interfaces, using OM3 fiber optic transmission, suitable for interconnection of 40G devices within 100m;
④ 40G QSFP+AOC connection 4 * SFP+AOC: suitable for interconnection between 40G and 10G devices, using OM3 fiber optic transmission, with one end having a 40G interface and the other end having four 10G interfaces.
In practical applications, it is recommended to use DAC high-speed cables for distances of 1-5M, AOC active optical cables for distances of 7-100M, and optical modules and optical cables for connections above 100M.
