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...

Daily maintenance of fusion splicer
Apr 09 , 2021
In the fusion state, the optical fiber advancement stops and the machine does not perform fusion operation. The reason is that the V-groove is dirty and must be cleaned. After closing the windproof cover, the optical fiber will not push forward. Reason: 1. The bare optical fiber is placed too far from the electrode or beyond the electrode, please replay the optical fiber. 2. The objective lens has...

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...

What does AUTO mean in splicing mode of optical fiber fusion splicer？
Jun 18 , 2021
AUTO automatically recognizes the fiber type and corrects the discharge parameter mode in real time. SM is a single-mode fiber mode, NZ is a non-zero displacement dispersion fiber mode, and DS is a displacement dispersion fiber mode. Optical fibers for communication are generally SM (single-mode) or MM (multi-mode), of which SM is the majority. SeikoFire S5 optical fiber fusion splicer is mainly u...

How to clean the fiber end face?
Jul 02 , 2021
In the optical communication system, it was found that the optical loss doubled for no reason, even the optical signal was cut off, and the network connection failed. After investigation, it was found that the "culprit" was actually a large number of invisible particles, dust, and dust on the end face of the optical fiber. Dirt such as oil stains. Therefore, the cleaning of the fiber end face shou...

Four Basic Steps to Complete a Proper Fusion Splicing
Jul 15 , 2021
Step 1. Preparing the Fibers 1. Strip jacket and remove an adequate amount of jacket, usually 2-3 m, for splicing and dressing the buffer tubes and fibers in the splice closure. Leave the proper amount of strength members to attach the cable to the closure. Refer to the splice closure directions for lengths needed. Clean all water-blocking materials using appropriate cleaners. 2. Remove buffer tub...

The Most Import Thing You Need To Know About Fiber Optic Power Meters
Jul 30 , 2021
Optical Power Meters Here The fiber optic power meter is a special light meter that measures how much light is coming out of the end of the fiber optic cable. The power meter needs to be able to measure the light at the proper wavelength and over the appropriate power range. Most power meters used in datacom networks are designed to work at 850nm and 1300nn. Power levels are modest, in the range o...

Why the fiber end face always appears bad when the fusion splicer is splicing?
Aug 04 , 2021
1. The new end face is contaminated by debris, dust, etc. Solution: Do not let the cut fiber end face touch anything; 2. When cutting the optical fiber, the angle is too large. In this case, it may be a problem with the cleaver blade. Change a blade for an interview, or there may be debris in the fiber groove of the cleaver. Use a sharp object to clean the fiber groove. ； 3. There are gray and dar...
