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...

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...

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...

what's the difference of fiber connector?
Aug 17 , 2021
Given the variety of splice options available to fiber network planners today identifying the best connector for FTTH can be overwhelming. Consequently often not much thought is given to connector selection with choice driven by cost, availability or what’s been used before. However each connector has its own unique design and therefore, pros and cons. Over time or depending on project...

Introduction and use of the optical cable identifier
Sep 17 , 2021
When using the optical cable identifier, the user only needs to tap the optical cable lightly to easily find the target. The built-in system of the instrument can convert the tapping information into audio and video signals. In other words, we can hear or see the target optical cable. Where. The optical cable identifier completely replaces the previous cutting, bending, freezing and other methods....

Ten reasons for excessive splicing loss of optical fiber
Feb 23 , 2022
1. Choose the wrong optical fiber splicing program; for example, misselect the single-mode splicing program to multi-mode. 2. The cutting angle of the end face of optical fiber is too large. 3. The optical system is dirty, mainly the reflector and objective lens. 4. V-shaped slot dirty, optical fiber pressure foot dirty. 5. The aging of the electrode leads to the weak discharge intensity, and the ...

Difference between G652 fiber and G654 fiber
Mar 18 , 2022
G.652 optical fiber is the most widely used optical fiber. At present, except for fiber-to-the-home (FTTH) home optical cables, almost all optical fibers used in long-distance and metropolitan areas are G.652 optical fibers. From the perspective of light energy distribution, the optical signal in the single-mode fiber is not only transmitted in the core, but also in the cladding. In ...
