How To Use OTDR?
Aug 14 , 2020
HOW TO USE OTDR? What is the most important thing to our OTDR? It must be looking at the graph and analyzing the curve. Then you can determine the condition of the line according to the curve. The operation mode and key function of each machine are basically different. First of all, we have to understand the basic operation and the key functions. We need to understand the most basic aspects of the...

Optical fiber will be the foundation of 5G network
Apr 01 , 2021
With the continuous changes in 5G wireless standards, what measures can network operators take to lay the foundation for 5G transmission networks? The good news is that at least the path of 5G at the physical layer is clear: optical fiber will be the foundation of 5G networks, and centralized RAN (C-RAN) will become the 5G network architecture. C-RAN was introduced through 4G (commercial de...

What does AUTO mean in splicing mode of optical fiber fusion splicer?
Jun 18 , 2021
AUTO automatically recognizes the fiber type and corrects the discharge parameter mode in real time. SM is a single-mode fiber mode, NZ is a non-zero displacement dispersion fiber mode, and DS is a displacement dispersion fiber mode. Optical fibers for communication are generally SM (single-mode) or MM (multi-mode), of which SM is the majority. SeikoFire S5 optical fiber fusion splicer is mainly u...

Four Basic Steps to Complete a Proper Fusion Splicing
Jul 15 , 2021
Step 1. Preparing the Fibers 1. Strip jacket and remove an adequate amount of jacket, usually 2-3 m, for splicing and dressing the buffer tubes and fibers in the splice closure. Leave the proper amount of strength members to attach the cable to the closure. Refer to the splice closure directions for lengths needed. Clean all water-blocking materials using appropriate cleaners. 2. Remove buffer tub...

What is OTDR Blind Area?
Aug 26 , 2021
Why does the blind area come up? The OTDR produces a blind area because the OTDR's detector is temporarily "blinded" by the high intensity Fresnel reflection light (mainly caused by the air gap between the OTDR connections). When the high intensity reflection is produced, the power of the photodiode is more than 4000 times higher than the backscatter power. Thus, the reflected light signal receive...

Introduction and use of the optical cable identifier
Sep 17 , 2021
When using the optical cable identifier, the user only needs to tap the optical cable lightly to easily find the target. The built-in system of the instrument can convert the tapping information into audio and video signals. In other words, we can hear or see the target optical cable. Where. The optical cable identifier completely replaces the previous cutting, bending, freezing and other methods....

OTDR test with light
May 24 , 2022
What is OTDR test with light? When testing with the wavelengths of 1310nm, 1490nm and 1550nm of common OTDR, it is necessary to require that there is no communication optical signal in the line under test. Forcing the test with light will burn out the internal detector of the OTDR. With light test, the OTDR can still complete the test without interrupting the signal light in the line during the te...

What is dynamic range of OTDR
Dec 15 , 2022
The dynamic range of an OTDR determines how long of a fiber can be measured. It is listed as a dB value — larger values generally mean longer distance measurement capability. A test pulse needs to be strong enough to get to the end of the fiber to be tested, and the sensor has to be good enough to measure the weakest backscatter signals which come from the end of a long fiber. The combination of t...
