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.

N7779C keysight Tunable Laser Source Description

The new N7779C Base Series tunable laser source, like the other new N777xC models, is ideal for cost-effective testing of broadband optical devices because of its ability to step quickly to discrete wavelengths with resolutions up to 0.1 pm and typical wavelength repeatability of ±3 pm. Short wavelength setup times (e.g., 300 ms) enable fast step scanning. Like other laser sources in the N777xC family, it delivers peak output power in excess of +12 dBm and low spontaneous emission levels. With power stability of ±0.01 dB per hour, it can also be used as a static local oscillator with a wide tuning range for receiver testing or transmission experiments.

Introduction and application of oscilloscopes (knowledge sharing)

Oscilloscope is a very wide range of electronic measuring instruments. It can transform the electrical signal invisible to the naked eye into a visible image, which facilitates people to study the change process of various electrical phenomena. The oscilloscope uses a narrow, high-speed electron beam composed of electrons, hitting the screen surface coated with fluorescent material, it can produce tiny dots of light (this is the traditional working principle of the analog oscilloscope).

The working principle of analog oscilloscope

The vertical input terminal (V terminal) on the panel of the analog oscilloscope is amplified by the vertical axis amplifier and then added to the vertical deflection electrode. At the same time, there is a horizontal scanning voltage generation circuit inside the analog oscilloscope, and the generated horizontal scanning sawtooth wave voltage is added to the horizontal deflection electrode of the analog oscilloscope. This circuit is also known as the time axis scanning oscillator circuit.
