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:...

(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), ...

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...

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 ...

Hello Readers, Below down we are going to talk about Classification of PON Modules and will try to describe you easily.  (1) OLT optical module and ONU optical module: According to the different classification of plug-in devices there are two types of PON optical modules: OLT optical module (this...

The difference between SFF, SFP, SFP+ and XFP optical modules classified according to different packaging types, PON optical modules can be divided into following types;   SFF optical module: This module is small in size, generally fixed, soldered on a fixed PCBA, and cannot be unplugged. Th...
