Frequently Asked Questions

SFP+ Transceivers and Cables

What is the maximum transmission distance of an SFP+ module?

The transmission distance varies depending on the type of SFP+ module. SR (Short Range) modules typically support up to 300 meters over OM3 MMF, while LR (Long Range) modules can reach up to 10 kilometers over SMF. Extended range modules like ER/ZR can support up to 40–80 kilometers, with 10GBASE-T SFP+ modules typically limited to 30/80 meters.

Can I use an SFP+ module in an SFP port?

No. SFP ports are designed for modules up to 1G speed. SFP+ modules require SFP+ ports capable of handling 10G speeds.

Are SFP+ modules hot-swappable?

Yes, SFP+ modules are hot-swappable, meaning you can insert or remove them without shutting down the network device.

What types of cables are compatible with SFP+ ports?

SFP+ ports are compatible with SFP+ optical transceivers (for fiber), Direct Attach Copper (DAC) cables, and Active Optical Cables (AOC).

Can I mix different types (SR, LR, ER) of SFP+ modules in one switch?

Yes, as long as each port's module matches the type of fiber and transmission distance it is designed for. However, both ends of a link must use the same type of module.

How to choose between DAC, AOC, and optical transceivers for SFP+?

Use DAC cables for short distances (<5m, cost-effective), AOC cables for medium distances (5–30m) with better flexibility, and optical transceivers for long distances (>30m or when connecting fiber infrastructures).

What is the typical power consumption of an SFP+ module?

The power consumption of SFP+ modules generally ranges from 0.8W to 1.5W, depending on whether it is SR, LR, ER, or ZR type.

What are the main differences between 10G CWDM SFP+ and 10G DWDM SFP+ compared to regular 10G SFP+?

Regular 10G SFP+ is for point-to-point direct optical transmission (850/1310/1550nm), with distance varying by model. CWDM/DWDM SFP+ utilizes coarse/dense wavelength division multiplexing with Mux/Demux to transmit multiple wavelengths over a single fiber for longer distances and higher capacity, but with increased cost and complexity.

What are the main differences in the application scenarios for 10G SFP+, 10G CWDM SFP+, and 10G DWDM SFP+?

10G SFP+: Point-to-point direct connection solution, supporting short-range (multimode) or medium-to-long-range (single-mode) 10G Ethernet links depending on the model.
10G CWDM SFP+: Multi-wavelength transmission solution, requires CWDM equipment, transmitting multiple 10G channels over a fiber pair for cost-effective capacity expansion in metro/access networks.
10G DWDM SFP+: High-density multi-wavelength transmission solution, requires DWDM equipment, transmitting a higher density of 10G channels over a fiber pair, ideal for long-haul, high-capacity backbone networks.
