JILONG Communications Vfl-22m /22P Visual Fault Locator on-line

VFL-22M Mini Visual Fault Locator

The VFL-22M mini VFL adopts a mini appearance design, which is not only easy to operate with one hand in daily use, but also light and portable; the body is made of frosted material, which is not easy to slip when holding it. This is simply for the communicator who loves sweating. It is "good news", because it is equipped with imported laser chips, it fully guarantees the strong and stable light source and strong penetrating power, 2.5mm universal interface, can be applied to SC, FC, ST, LC (optional) and other connector interfaces. There are three power product models of 10mW, 20mW and 30mW, and the test distance can reach 25~30KM, and the two detection methods of constant light and flashing can be switched with one button, allowing you to easily check out problems such as line faults.

Optical fiber cables are so fast, why are network cables more popular?

The bandwidth of optical fiber is larger than that of ordinary network cable, and it is much better than network cable in terms of network speed. Therefore, fiber to the home is also a choice of many people. However, although fiber to the home is excellent, it is not so popular in many home groups. Most home networks use network cables. The question is, why is this？

Cost

First of all, the first reason is very simple, the cost between optical fiber and network cable. Optical fiber sounds expensive, but in fact it is not. However, optical fiber networks are not only as simple as intermediate connections requiring optical fibers, but more importantly, all optical fibers used must be optical interface cards. Even today, when the network is so developed, the price of optical interface cards in pure optical fiber network LANs is still much higher than that of ordinary network cards.Secondly, because home routers and home switches with optical ports are not popular, the ess

2020 China International Optoelectronic Exposition-Optical Communications

On September 11, 2020, the 22nd China International Optoelectronic Expo (CIOE 2020) was successfully concluded at the Shenzhen International Convention and Exhibition Center (Bao'an). Although this exhibition was affected by the epidemic, there were still a lot of people in various venues during the exhibition, especially Hall 4 of the Information and Communication Exhibition. In Hall 4, many well-known optical communication companies at home and abroad, such as Huawei, Nokia Bell, YOFC, and JILONG Communications, gathered together to exchange and learn from each other. For JILONG Communications, it not only can learn industry technology, but also The zero distance communication and exchanges between JILONG and agents and customers have laid a solid foundation for future cooperation with each other.

 

How to use optical fiber quick connector and mechanical splicer

The vigorous development of optical communication technology has led to the rise of fiber to the home, which has led to the continuous expansion of the market for optical fiber quick connectors and cold splices.

 

What is the difference between optical fiber quick connector and mechanical splicer?

The optical fiber mechanical splicer has the same structural principle as the embedded optical fiber connector, and belongs to the sub-product of the optical fiber quick connector. Because its shape is similar to the quick connector, many people are not clear about the two.

The difference between the mechanical splicer and the optical fiber quick connector is that it has no movable plug. It is used to directly fix the optical link node when the optical fiber is connected to the optical fiber or the optical fiber and the pigtail. The contact loss is about 0.1dB~0.2 dB. Mainly used for indoor wiring or wiring in narrow spaces, making installation more con
