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...

What is the difference between single-mode fiber and multi-mode fiber? Which one to choose?
Sep 21 , 2020
The first is to introduce the difference between multimode fiber and single mode fiber: Multimode fiber The optical signal in multimode fiber propagates through multiple channels; it is usually recommended to be used when the distance is less than miles. The effective distance of multimode fiber from transmitter to receiver is about 5 miles. The usable follow-up is also affected by the type and qu...

How to Use VFL
Nov 04 , 2020
VFL is very easy to use. The steps to use a VFL are provided as following: Step One: remove the plastic connector covers from both ends of the test fiber cable. Step Two: connect the fiber optic visual fault locator one end of the fiber. Press the tester button and observe that light emanates from the other end of the fiber. This gives a simple indication of the continuity of the fiber link. Step ...

The correct use of fiber stripper
Mar 17 , 2021
Professional tools should be used when stripping the coating layer of the optical fiber. The most typical tool is the Fiber Stripper; it can thin the plastic outer layer outside the pigtail, and it can also strip the coating layer of the optical fiber. Pay attention to: 1. When peeling off the coating layer of the optical fiber, there should be no impurities in the small holes of the fiber strippe...

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...

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...
