  • 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'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...

  • 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...

  • 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...

  • What is fiber to the home?(FTTH) Oct 03 , 2020
    What is fiber to the home (FTTH)? - Structure and components FTTH is one of the most important technologies for today and future’s networks, because not only it increases the access to bandwidth, but reduces equipment and maintenance cost while intensely improving Quality of Service. Projections specify that individual user Internet use will reach 100Mbps and will eventually go to 1Gbps. And fiber...

  • 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...

  • Introduce of Optical Power Meters Aug 31 , 2020
    Introduce of Optical Power Meters An optical power meter (or laser powermeter) is an instrument for the measurement of the optical power (the delivered energy per unit time) in a light beam, for example a laser beam. Typically, it allows for power measurements only with a relatively low bandwidth, and will e.g. display only the average power when receiving a pulse&nbs...
