What is the rate of SFP DD?
Knowledge Base + 2024.01.12

SFP-DD (Small Form-factor Pluggable Double Density) is a next-generation optical transceiver form factor that supports higher data rates compared to traditional SFP (Small Form-factor Pluggable) modules. SFP-DD modules are designed to double the data rate density while retaining backward compatibility with existing SFP ports. The data rates supported by SFP-DD modules include:

  1. SFP-DD (Single Channel):

    • Supports data rates of 25 gigabits per second (Gbps) per channel.

  2. SFP-DD (Double Channel):

    • Supports data rates of 50 gigabits per second (Gbps) for a double-channel configuration.

  3. SFP-DD (Quad Channel):

    • Supports data rates of 100 gigabits per second (Gbps) for a quad-channel configuration.

SFP-DD modules are versatile, and the quad-channel configuration is particularly relevant for applications such as 400 Gigabit Ethernet. The SFP-DD interface retains the same size and form factor as traditional SFP modules, allowing for compatibility with existing SFP ports while providing the potential for higher data rates by using multiple channels.

It's worth noting that the specific data rates can depend on the implementation and configuration of the SFP-DD module. Always refer to the specifications provided by the manufacturer for accurate information on the data rates supported by a specific SFP-DD module.
