Description

Signal transmission line

The invention relates to a signal transmission line, in particular to a signal transmission line which can be utilized in the technical field of optical fibers and can be conveniently used for checking and checking when installing or checking lines.

With the popularity of fiber-to-the-home (FTTH) engineering, optical fibers are widely used because of their small size, light weight, and reliable transmission. For example, it is widely used in FTTH outdoor network systems, intra-office high-speed fiber-optic network wiring, fiber-optic broadband building vertical cabling, horizontal cabling, and FTTH cable cabling. However, when the number of optical fibers is too large or the colors are too close, it is very easy to cause misjudgment. Therefore, the widely used fiber-resolved marking technology is usually a method of labeling and numbering, for example, to identify a machine room-cabinet (row/column)-cabinet (several floors)-box (several roads) The fiber is labeled with a custom label number: A1-3/4-04-48.

But this traditional approach has the following obvious drawbacks:

1. For different fiber installation projects, the number of fiber jumper labels defined by different engineers and construction personnel may be different, and new engineers and construction personnel cannot understand the way in which the previous engineers and construction personnel jumped the label number;

2. Due to the different number of fiber jumper labels, the label number will be mislabeled or peeled off due to human factors;

3. The label number is too long, or it is faded and not easy to identify due to the long time of use;

4. When inquiring the line, the engineer must first record the number of the label and then find the corresponding line. When it is found, a lot of time has been wasted. If the engineer mis-numbers, the other normal lines will be disconnected.

The occurrence of the above phenomenon has greatly reduced the efficiency of construction and maintenance of the fiber optic system, and may also cause unnecessary disconnection problems. Therefore, the industry urgently needs to solve the technical problem of identifying the inconvenience of the paired fiber jumper in the construction and maintenance of the optical fiber communication.

In view of this, the present inventors have focused on the lack of construction and inspection check of the above-mentioned optical fiber transmission line, and actively research and improve in the spirit of perseverance and refinement, and finally develop and design through long-term efforts and experiments. The present invention has been developed.

The main object of the present invention is to solve the above problems and to provide a signal transmission line which can be utilized in the technical field of optical fibers and can be easily searched for when installing or checking lines.

To achieve the above objective, the optical fiber jumper is taken as an example, and the present invention mainly includes an optical fiber cable and a fiber optical connector disposed at both ends of the optical fiber cable. An alarm is respectively disposed on the optical fiber line adjacent to the fiber connectors at both ends, and the two alarms are connected through two wires integrally formed with the optical fiber and forming a loop, when one of the alarms is powered on, The warnings will send a warning signal at the same time. Then, when people install and maintain, for a large number of fiber jumpers, as long as the power of a warning device of the fiber jumper is turned on, the warning device at both ends of the fiber jumper will be bright or sound, and people can easily Identify which is the same fiber jumper, reducing human error and installation time. The invention has simple structure and convenient manufacture, and can greatly improve the working efficiency of installation, jumper and maintenance of the optical fiber system.
