How is the Submarine Cable Laid?
Jun 09 , 2020
The submarine communication cable is a wire wrapped with insulating material and laid on the seabed to complete the telecommunications transmission between countries. The first batch of submarine communication cables were used to supply telegraph communications, and later began to introduce telephone communications and Internet communications. Modern fiber optic cables also used fiber optic skills...

How To Use The Optical Power Meter?
Aug 20 , 2020
Optical power meter refers to an instrument used to measure absolute optical power or the relative loss of optical power through a section of optical fiber. Simply put, it is to measure the attenuation of the optical signal after fiber transmission. Simple instructions: 1. When measuring the absolute optical power with the optical power meter, just connect the light source and look at the value in...

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...

The Basic Principles of OTDR
Oct 15 , 2020
OTDR is called Optical Time Domain Reflectometer, which injects narrow light pulses into the fiber end face as a detection signal. When the light pulse propagates along the fiber, the backscattered part of Rayleigh scattering everywhere will continue to return to the incident end of the fiber. When the optical signal encounters a crack, Fresnel reflection will occur, and the back reflected light w...

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 ...

Precautions for using VFL
Feb 03 , 2021
Visual Fault Locator are also called VFL, pen-type red light sources, visible light detector, optical fiber fault detectors, optical fiber fault locators, etc. Most of them are used to detect fiber breakpoints. According to their shortest detection distance, they are divided into: 5Km, 10Km, 15Km, 20Km, 25Km, 30Km, 35Km, 40Km, etc. Driven by a constant current source, a stable red light is emitted...

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...
