  • 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...

  • 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...

  • Optical fiber will be the foundation of 5G network Apr 01 , 2021
      With the continuous changes in 5G wireless standards, what measures can network operators take to lay the foundation for 5G transmission networks? The good news is that at least the path of 5G at the physical layer is clear: optical fiber will be the foundation of 5G networks, and centralized RAN (C-RAN) will become the 5G network architecture. C-RAN was introduced through 4G (commercial de...

  • What's PON? What's PON optical power meter? Apr 14 , 2021
    PON (Passive Optical Network) The system is mainly composed of OLT (Optical Line Terminal), ONU (Optical Network Unit) and ODN (Optical Distribution Network) in the optical distribution network. Among them, the ODN does not include active equipment, and the OLT to the ONU is connected through an optical splitter to form a P2MP (point-to-multipoint) optical access system. PON can save optical fiber...

  • 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...

  • OTDR: General Questions Apr 28 , 2021
    Q: What do OTDRs test? A: OTDRs test the overall length, loss and optical return loss of fiber optic cables or networks. Additionally, they detect, locate, identify and measure optical components in installed networks including fusion splices, optical connectors and PON splitters as well as faults such as breaks or tight bends causing high loss. Q: Does it take training to use an OTDR? A: Each OTD...

  • 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...
