Fusion Splicer Maintenance how to Clean its V-groove?
Jun 09 , 2020
Fusion splicer is a high precision equipment, it is very import to do the maintenance during daily work. V-groove is a V slot on the ceramic substrate of narrow width, easily to accumulate dust which will make the fiber move instability and cause a bad fusion, therefore, the V groove should be cleaned regularly. The following is the way of cleaning the V-groove

How To Use The Optical Power Meter?
Aug 20 , 2020
Optical power meter refers to an instrument used to measure absolute optical power or the relative loss of optical power through a section of optical fiber. Simply put, it is to measure the attenuation of the optical signal after fiber transmission. Simple instructions: 1. When measuring the absolute optical power with the optical power meter, just connect the light source and look at the value in...

Introduce of Optical Power Meters
Aug 31 , 2020
Introduce of Optical Power Meters An optical power meter (or laser powermeter) is an instrument for the measurement of the optical power (the delivered energy per unit time) in a light beam, for example a laser beam. Typically, it allows for power measurements only with a relatively low bandwidth, and will e.g. display only the average power when receiving a pulse&nbs...

The Basic Principles of OTDR
Oct 15 , 2020
OTDR is called Optical Time Domain Reflectometer, which injects narrow light pulses into the fiber end face as a detection signal. When the light pulse propagates along the fiber, the backscattered part of Rayleigh scattering everywhere will continue to return to the incident end of the fiber. When the optical signal encounters a crack, Fresnel reflection will occur, and the back reflected light w...

The Basic knowledge of PON
Nov 11 , 2020
1.1 Basic principles of PON system PON (passive optical network) refers to an optical access network in which the ODN (optical distribution network) between OLT (optical line terminal) and ONU (optical network unit) all adopts passive equipment. PON is a point-to-multipoint (P2MP) optical access system, which can save fiber resources, ODN does not require power supply, user access is convenient, a...

The Notes When Using OTDR
Nov 26 , 2020
1. Simple judgment of fiber quality: Under normal circumstances, the slope of the main body of the light curve (single disk or several optical cables) tested by OTDR is basically the same. If the slope of a certain section is large, it indicates that the attenuation of this section is large; if the main body of the curve is of irregular shape, the slope fluctuation is large. Bending or arcing indi...

What is the FTTx?
Dec 16 , 2020
FTTx is the abbreviation of “Fiber to the X”, which means “fiber to x”, which is a general term for various fiber-optic communication networks, where X represents the destination of the fiber-optic line. The FTTx network applications in GPON access have the following in common: The data, voice, and video signals of terminal users are sent to ONUs, where the signals are converted into Ethernet pack...

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...

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...

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 are reflective and non-reflective events in otdr?
Jan 21 , 2022
1. The height of each point in the OTDR curve represents the backscattered light intensity at that location. When looking at the OTDR curve, you can see that the reflected signal is raised in some places, as if the optical power at the back is stronger than the front, which is impossible. Generally, this situation is the backscattering peak caused by the Fresnel reflection at the splicing, breakin...
