Testing the parameters of optical modules

In using the use of optical modules, it is unavoidable to encounter a variety of problems. In order to reduce the problematic failure phenomenon, but also to protect the stability of the optical module through. There will exist different detection functions for optical modules. 1X9 module is main... Read More

Optical Module Output Optical Power

The output optical power (Output Power) refers to the average output optical power of the light source at the transmitting end of the optical module, also called the output optical power, which can be understood as the intensity of light. Formula: P(dBm)=10Log(P/1mW) The unit is W or mW or dBm. (... Read More

Fibre-optic interfaces for optical modules

This refers to the interface of an optical module to a fibre optic patch cable, which can be connected via single mode or multimode fibre optic cable. The following is an analysis of this according to the different interfaces.  At present, the main optical interfaces on the market are: MPO, LC, S... Read More

Laser class of SFP modules

At present, there are FBG, FB and DFB lasers, Among them, the most commonly used lasers are FP and DFB.   FBG: Fiber Bragg Grating. FP: Fabry-Perot, Fabry-Perot Laser Diode DFB: Distributed Feedback Laser, Distributed Feedback Laser Diode   For the mainstream commonly used FB and DFB. The DFB las... Read More

What Causes Loss in fiber optics transmission?

In this article I’m gonna talk about what causes loss in fiber optics transmission. Let’s learn… The reason why optical fiber replaces the medium and long-distance transmission of network cables is because optical fiber transmission has low loss, and its loss is mainly divided into the following:...

The three major parameters of optical modules

(i) Center wavelength The working wavelength of the optical module is actually a range, but there will be obvious differences between single-mode and multi-mode. Then the expression is generally named according to the most central wavelength. The unit of central wavelength is a nanometer (nm), ... Read More
