  • 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...

  • 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...

  • What are the commonly used fiber optic tools? Jan 21 , 2021
    The gradual increase in the construction and maintenance of optical cables in the optical communication industry has prompted an increase in the demand for various optical fiber tools. Common optical fiber tools on the market include optical fiber strippers, optical cable strippers, and optical cable cutting shears. The purpose of these tools is also different, are you really familiar with them? K...

  • 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...

  • What's fiber optic pigtail? Jan 06 , 2021
    A fiber pigtail is a single, short, usually tight-buffered fiber optic cable with a factory-installed connector on one end, and un-terminated fiber on the other end, making the maintenance more conveniently. Fiber optic pigtails are used to terminated fiber optic cables via fusion splicing or mechanical splicing as shown in the picture below. The end of the pigtail is stripped and fusion spli...

  • 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...

  • The simple failure analysis and elimination of fusion splicer Dec 23 , 2020
    1. During the splicing process, the fusion splicer displays "fiber not found or the end face of the fiber is untidy". This is mainly caused by the surface of the optical system being contaminated. The protective glass (located under the electrode) should be cleaned with absolute alcohol, and the lens on the fiber cover should be cleaned at the same time. Wait until the alcohol is dry before procee...

  • What is the FTTx? Dec 16 , 2020
    FTTx is the abbreviation of “Fiber to the X”, which means “fiber to x”, which is a general term for various fiber-optic communication networks, where X represents the destination of the fiber-optic line. The FTTx network applications in GPON access have the following in common: The data, voice, and video signals of terminal users are sent to ONUs, where the signals are converted into Ethernet pack...
