What is the difference between SFP56 and SFP28 optical transceivers?

The main difference is the supported data rate. SFP28 modules are designed for 25Gb/s transmission, while SFP56 modules support 50Gb/s by using higher-speed electrical interfaces. SFP56 provides a higher bandwidth option while maintaining a similar compact form factor for next-generation Ethernet networks.

What transmission distance can this 50G SFP56 LR module achieve?

This module supports transmission distances of up to 10km over single-mode fiber, making it suitable for medium-distance connections such as data center interconnects, enterprise backbone links, and campus network applications.

Why does this module use a 1310nm DFB laser?

A 1310nm DFB (Distributed Feedback) laser provides stable wavelength output, excellent optical performance, and efficient transmission characteristics over single-mode fiber. It is widely used in Ethernet optical modules requiring reliable transmission over several kilometers.

What information can be monitored through the DDM function?

The built-in DDM function allows network operators to monitor important operating parameters, including optical transmit power, optical receive power, module temperature, supply voltage, and laser bias current through the 2-wire serial interface.

Is this 50G SFP56 LR module compatible with existing network equipment?

The module can be customized with different coding options to support compatibility with various switches, routers, and networking platforms. Customers can provide their equipment models for compatibility verification before deployment.
