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 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...

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 ...

The Basic knowledge of PON
Nov 11 , 2020
1.1 Basic principles of PON system PON (passive optical network) refers to an optical access network in which the ODN (optical distribution network) between OLT (optical line terminal) and ONU (optical network unit) all adopts passive equipment. PON is a point-to-multipoint (P2MP) optical access system, which can save fiber resources, ODN does not require power supply, user access is convenient, a...

The Notes When Using OTDR
Nov 26 , 2020
1. Simple judgment of fiber quality: Under normal circumstances, the slope of the main body of the light curve (single disk or several optical cables) tested by OTDR is basically the same. If the slope of a certain section is large, it indicates that the attenuation of this section is large; if the main body of the curve is of irregular shape, the slope fluctuation is large. Bending or arcing indi...

Why is My Internet So Slow? It Maybe Because of Network Cables!
Dec 29 , 2020
With the development of communication technology and the Internet, operators began to offer home broadband services of 200 Mbps, 500 Mbps and 1Gbps to ordinary consumers to meet the bandwidth needs of different users. However, when some users tested the network speed of computers, mobile phones and tablets connected through routers after the high-speed broadband service was opened, they found that...

What are the main functional differences between OTDR and optical power meters?
Jan 13 , 2021
Anyone who does optical cable construction will often come into contact with optical power meter and OTDR (optical time domain reflectometer). Multi-users do not understand why it is necessary to use an optical power meter to test the optical loss after testing the OTDR. Doesn't OTDR have the function of testing fiber loss? And there are some differences in the main functions of the two devices? O...

How does otdr measure breakpoints?
Feb 19 , 2021
The fiber breakpoint measurement with OTDR can be divided into three steps: parameter setting, bai data acquisition and curve analysis. Manual setting of measurement parameters includes: (1) Wavelength selection (λ): Because different wavelengths correspond to different light characteristics (including attenuation, microbending, etc.), the test wavelength generally follows the principle correspond...

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...
