In recent years, the fiber optic network has developed rapidly. Under the influence of fiber splicing machines, most countries have successfully launched the overall layout of fiber optic networks. According to the relevant arrangement of the country, 5G commercial trials will be conducted in more than 20 cities throughout the country this year, and will officially begin commercializatio...

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

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...

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...

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...

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...

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...

1. Overall planning.  With reference to the development requirements of the broadband access network in the Chinese market, and combined with the characteristics of the current GPON products and the specific operation of the current network deployment, it is recommended to adopt the FTTH construction mode, with the ability to provide ultra-high bandwidth for end users, and to bring functional...

PON is the abbreviation of passive Optical Network (Passive Optical Network).  Usually we can surf the Internet at home and rely on PON (passive Optical Network).  The advantage of passive optical network is that it is a pure medium network, which avoids the electromagnetic interference and lightning influence of external equipment, reduces the failure rate of lines and external equipmen...

When we browse the web at home when the broadband network speed is not stable, watching video suddenly lag, the game is playing when the excitement suddenly disconnected and other phenomena occur, it is likely that the home optical cat ONU weak light! What is called optical cat ONU weak light?ONU is what we commonly known as optical cat equipment, used to convert optical signals on the optical fib...

Both gpon and epon belong to infinite light source network technology, referred to as PON, which includes gpon and epon. It is a high-tech technology for the development of fiber-to-the-home. The implementation of this technology can not only save backbone fiber resources and network levels, but also speed up network transmission and improve the pull-in capacity of broadband. It has more types of ...

PON (Passive Optical Network) Power Meter is a special instrument used to test the optical power of passive optical network (PON). PON is a kind of optical fiber communication technology, which is widely used in fiber-to-the-home (FTTH) network to provide users with high-speed broadband access. The main function of PON Power Meter is to measure the power of optical signals to ensure the transmissi...

The Optical Time Domain Reflectometer (OTDR) is a powerful instrument widely used in the field of fiber optics for characterizing and testing optical fibers. OTDRs provide valuable insights into the physical properties of fiber, such as attenuation, splice loss, and fiber length. In this article, we will delve into the operating principles of OTDR and gain a better understanding of how this instru...

A PON (Passive Optical Network) power meter is a device used to measure the optical power levels in a PON system. PON is a technology used in fiber optic communication networks to provide high-speed data, voice, and video services to end-users. A PON power meter is specifically designed to measure the power levels at different points in a PON network, including the Optical Line Terminal ...
