FAQ

1. Background of the problemDuring the testing process of the 10G BIDI project, it was found that the alarm would be delayed or even not triggered. It was further discovered that the module alarm (LOS-A) and de alarm (LOS-D) were normal when not mounted, and the sensitivity (SEN) would also increase

1. BackgroundWhen testing the GPON module of the MS solution for ZTE customers, during the ONU and OLT connection process, when the first BEN signal is enabled, the "0" level is raised very high; When the first long light emission occurs, the process of establishing the light signal slowly

Overview of EPON OLT Optical ModuleWhen the OLT optical module is working, the downlink uses broadcasting to continuously transmit data streams, and each ONU can receive the OLT signal, regardless of whether the signal is for itself. Therefore, the transmission of the OLT in the downlink direction i

Single fiber SFP optical module is a type of fiber optic communication device that uses single fiber bidirectional transmission technology, requiring only one fiber for bidirectional communication. Its advantages and disadvantages are as follows:1、 Advantages:a. Fiber saving: Single fiber SFP optic

SFP optical modules are increasingly receiving high attention in communication work. SFP optical modules are one of the highly anticipated modules. Below, we summarize the basic knowledge of SFP optical modules from multiple levels, hoping to provide you with necessary help.1. Definition of SFP opti

As a sensitive optical device, optical modules sometimes encounter some problems during use. Below, ETU-LINK will list some common problems and solutions for optical modules in use. Let's learn together!Problem 1: The optical port light does not light up after the interconnection of two optical

During the use of optical modules, various problems are inevitable. When we connect the optical module to the optical module through fiber optics, there may be situations where the optical port light is not on, the optical port light is red, or an alarm or failure of the optical module occurs. So, w
