AQ6370D Spectrum Analyzer: Accurate Measurements with DWDM System

With the rapid advancement of 5G networks, optical communication technology has ushered in unprecedented changes. Dense wavelength division multiplexing (DWDM) systems have become the core of modern fiber optic communication networks due to their efficient data transmission capability and spectrum utilization. However, the dense channel distribution and high-speed data transmission in DWDM systems place higher requirements on the optical spectrum analyzer (OSA).

What is the difference between SR, LR, LRM, ER and ZR in 10G optical modules?

SR, LR, LRM, ER and ZR are the more common module types in the 10GIEEE standard, but what is the difference between 10g SR, LR, LRM, ER and ZR? First we need to know what they represent. In fiber optic communication, SR, LR, LRM, ER and ZR are a kind of distance terminology in 10G optical module transmission, SR means short distance, LR means long distance, LRM means length extended multipoint mode, ER means ultra-long distance, and ZR means the longest distance.

10G Optical Module Eye Diagram Testing in a Nutshell

10G optical module eye diagram test is an important means to evaluate the performance of optical modules, which is a method to obtain the performance parameters of optical modules by monitoring and analysing the optical signals in real time. During the testing process, the optical signal is converted into an electrical signal and displayed through the waveform of an oscilloscope. By analysing the waveform, various parameters of the eye diagram, such as eye height, eye width, extinction ratio, etc., can be obtained to evaluate the performance of the optical module.
