SFP+ optical modules can flexibly select matching fiber types according to actual application requirements. This flexibility is conducive to improving the cost-effectiveness and performance of the network.

Key factors for selecting SFP+ matching fiber optic cables

Let me analyze in detail the key factors that need to be considered when selecting SFP+ matching fiber optic cables.

The impact of transmission distance and bandwidth on cable selection:

1. Transmission distance:

• Choose the appropriate fiber optic transmission distance according to the actual needs of network deployment.
• Multimode fiber can be used for shorter distances, while single-mode fiber is required for long distances.

2. Transmission bandwidth:

• Choose fiber optic cables with corresponding performance according to the bandwidth requirements of network applications.
• If 10GbE applications require bandwidths up to 2000MHz·km, OM3/OM4 multimode optical fiber should be used.

3. Performance matching:

• The technical parameters of the optical fiber cable need to match the performance of the SFP+ module.
• Avoid the situation where the optical fiber bandwidth cannot meet the rate of the SFP+ module.

Physical compatibility and cost factors of optical fiber cables:

1. Physical compatibility:

• Ensure that the selected optical fiber cable is physically compatible with the optical interface of the SFP+ module.
• For example, single-mode optical fiber requires an LC interface, while multimode optical fiber commonly uses an SC interface.

2. Cost factors:

• Choose the appropriate fiber optic cable cost according to the budget and application scenarios.
• Generally speaking, the cost of multimode fiber is lower than that of single-mode fiber, but the transmission distance is limited.

3. Compatibility and cost trade-off:

• Try to choose a fiber optic cable with more cost advantages while meeting physical compatibility.
• However, if the network requirements cannot be met, performance indicators should be prioritized rather than cost.

In general, the selection of SFP+ supporting fiber optic cables requires comprehensive consideration of transmission distance, bandwidth, physical interface, cost and other factors to ensure the performance and economy of network applications.
