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

PON Optical Module and Traditional Optical Module

According to the different classification of development time: Optical modules are divided into two types: PON optical modules and traditional optical modules. When using traditional optical modules: The optical signal transmission mode is point-to-point (P2P: one transmission to one), the module... Read More

Comparison of GPON and EPON optical modules

Hello, Welcome. Let’s learn the comparison between GPON and EPON optical modules in easy description. GPON optical module has better performance than EPON optical module. In terms of speed, downlink is better than EPON; In terms of business, GPON covers a wider range; From the transmission ... Read More
