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...

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...

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...

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...

What is OTDR Blind Area?
Aug 26 , 2021
Why does the blind area come up? The OTDR produces a blind area because the OTDR's detector is temporarily "blinded" by the high intensity Fresnel reflection light (mainly caused by the air gap between the OTDR connections). When the high intensity reflection is produced, the power of the photodiode is more than 4000 times higher than the backscatter power. Thus, the reflected light signal receive...

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.
