The knowledge of photoelectric composite cable
Sep 01 , 2021
Photoelectric composite cable refers to a transmission line suitable for broadband access network systems. It is a new type of access method. It integrates optical fiber and copper wire for power transmission. It can solve the problems of broadband access, equipment power consumption, and signal transmission. structure Photoelectric composite low-voltage cables (referred to as photoelectric compos...

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...

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...

Classification of optical fiber loss.
Aug 13 , 2021
The optical fiber loss can be divided into the inherent loss of the optical fiber and the additional loss caused by the service conditions after the optical fiber is made. The details are as follows: Optical fiber loss can be divided into inherent loss and additional loss. The inherent loss includes scattering loss, absorption loss and the loss caused by the imperfect structure of optical fib...

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...

Why can't the OTDR test, how to test?
Jul 26 , 2021
For our communication, OTDR is the equipment that we usually have to get in touch with, so analyzing OTDR and detecting faults is a skill we need to learn So what aspects should we start with if the OTDR test fails? Next, the editor will take you to learn more about how to detect OTDR problems. Especially when it can't be tested. 1. The optical port is not plugged in properly. Our OTDR optical por...

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...

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...
