Therefore, 10GBE SFP+ emerged as the times require, providing higher data transfer rates and smaller size to adapt to these application scenarios.

SFP+ interface:
The SFP+ interface is the physical connection interface of the 10GBE SFP+ optical module. It has the following characteristics and functions:

  • Small size: The SFP+ interface is smaller and smaller, allowing the 10GBE SFP+ optical module to be used in limited spaces and suitable for high-density optical fiber connection scenarios. Compared to larger XFP or XENPAK interfaces, SFP+ interfaces can provide higher port density.

  • Hot-swappable: The SFP+ interface supports hot-swappable functionality, allowing optical modules to be plugged and unplugged during operation without shutting down the device or interrupting the network connection. This makes it more convenient and flexible to replace, upgrade or maintain optical modules.

  • High rate: The SFP+ interface supports a data transfer rate of 10GBps, meeting the requirements of 10 Gigabit per second Ethernet. It can be connected to other 10GBE devices through fiber optic cables to achieve high-speed data transmission and communication.

  • Multi-mode and single-mode: The SFP+ interface supports multi-mode and single-mode fiber optic connections to adapt to different fiber types and transmission distance requirements. Multimode fiber is suitable for shorter distance connections, while single mode fiber is suitable for longer distance connections.
