The transmission distance of the InfiniBand cable depends on the type, rate, and quality of the cable.
According to the IBTA standard, the maximum transmission distance of InfiniBand cables is shown in the following table:
|
Rate |
Copper Cable |
Fiber Optic Cable |
|
SDR (10 Gb/s) |
15m |
300m |
|
DDR (20 Gb/s) |
10m |
300m |
|
QDR (40 Gb/s) |
7m |
300m |
|
FDR (56 Gb/s) |
5m |
300m |
|
EDR (100 Gb/s) |
3m |
100m |
|
HDR (200 Gb/s) |
3m |
100m |
|
NDR (400 Gb/s) |
2m |
100m |
It can be seen that the maximum transmission distance of copper cables decreases with the increase of the rate, while the maximum transmission distance of fiber optic cables is relatively stable.
However, these data are only theoretical limit values, and factors such as the quality of the cable, the loss of the connector, and the temperature and humidity of the environment must also be considered.
Therefore, when choosing InfiniBand cables, you need to consider the performance and cost of the cables according to the actual network needs and conditions.
