Why Do You Need OTDR Launch Box?
Mar 24 , 2021
Optical Time Domain Reflectometer (OTDR) is a mandatory fiber optic testing tool which uses light backscattering technologies to analyze optical fiber performance. An OTDR can test the light loss and locate the breaks, splices and connectors in fiber optic network. However, an OTDR has a “Dead Zone“ which can affect the test results. To overcome the limitation of this OTDR dead zone, an OTDR Launc...

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...

Why we need OCID?
Apr 23 , 2021
As demand for optical fiber increases day by day,the numbers of fibers in a single optical cable can be as many as 2096 individual fibers.As more fiber cables are buried underground,it becomes extremely dificult for the telecom engineers and technicians to manage the cables because cables may take different pathways, or be labeled incorrectly. As vast large number of optical cable being deployed b...

How to distinguish SM and MM fiber？
May 07 , 2021
According to the transmission mode of light in the fiber, it can be divided into: single-mode fiber and multi-mode fiber. The core diameter of the multimode fiber is 50-62.5μm, the outer diameter of the cladding is 125μm, the core diameter of the single-mode fiber is 8.3μm, and the outer diameter of the cladding is 125μm. The working wavelength of the optical fiber has short wavelength 0.85μm, lon...

The Most Import Thing You Need To Know About Fiber Optic Power Meters
Jul 30 , 2021
Optical Power Meters Here The fiber optic power meter is a special light meter that measures how much light is coming out of the end of the fiber optic cable. The power meter needs to be able to measure the light at the proper wavelength and over the appropriate power range. Most power meters used in datacom networks are designed to work at 850nm and 1300nn. Power levels are modest, in the range o...

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...

Do you know what kinds of optical fiber connectors there are?
Sep 10 , 2021
In the field of optical fiber, optical fiber interface (also known as optical fiber connector) is a common product, which is a detachable device between optical fiber and optical fiber, and connects the two ends of optical fiber. It is not only connected to the optical fiber, but also can be repeatedly plugged and unplugged, so it has also become a movable connector of the optical fiber. With the ...

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....

What are reflective and non-reflective events in otdr?
Jan 21 , 2022
1. The height of each point in the OTDR curve represents the backscattered light intensity at that location. When looking at the OTDR curve, you can see that the reflected signal is raised in some places, as if the optical power at the back is stronger than the front, which is impossible. Generally, this situation is the backscattering peak caused by the Fresnel reflection at the splicing, breakin...
