Network and telecommunications connectors are devices used to transmit data and provide telephone services to the world. There are a wide range of RJ connector series on the market. Although some sizes or applications may overlap, each has its own connector format and application range. The division of different RJ connectors is sometimes based on the number of telephone lines in the telecommunications system and the need for data transmission, so different wiring arrangements are provided through various connectors.

Network and telecommunications connectors are arguably the most widely used connectors. Most home users use Ethernet cables to connect computers and modems, and both ends of the cable need telecommunication connectors to connect. And it is not difficult to find various connectors between phones, computers, gateways and other hardware.

The appearance of the telephone has a history of more than 140 years. The original telephone set was connected to the telephone bus and the switch in a winding manner, and the appearance of the telephone connector was about the 1900s. There are many different specifications of telecommunications connectors, but they are all standardized products, making it easy for technicians, engineers, and system designers to find the components needed for any task. In the early days, telephone lines in the United Kingdom were managed by the postal authority, so there was a unified connector specification, and now the BS6312 standard is used; the telephone connector in the United States depends on the design of the telephone company, and finally the RJ11 connector developed by Bell in 1976. Dominate the world".

A variety of network and telecommunications connectors are found in offices, commercial and industrial locations. They include some products designed for very harsh environments, and some are types that are provided for daily work environments such as offices.

Even the old RJ connectors, which are "ubiquitous and everywhere" at the same time, actually represent some impressive achievements in the history of telecommunications. You can’t imagine that they have not been recognized and applied by the mainstream before the 1960s, but because of their easy-to-use design and sturdy and durable features, they are still long-lasting devices. There are many telephone cables with assembled RJ connectors on the market, but kits for terminating or connecting cables are also easy to find, and almost all telecommunications technicians are familiar with their use.


Network connectors and telecommunications connectors can be distinguished from the naked eye. RJ11, RJ14 and other interfaces used for telephone connections are smaller in size than RJ45 interfaces for Ethernet applications.

Of course, some telecom jacks are slightly different from common RJ jacks. For example, although MMJ connectors are improved versions from standardized RJ connectors, they are not compatible with other RJ connectors.

With the advent of optical fiber communication technology, more and more network and telecommunications connectors support this application, becoming one of the most significant advancements in the telecommunications industry in recent decades. Optical fiber connectors are the newest member of the telecommunication connector world and are rapidly gaining wide application. Most large telecom companies have adopted optical fiber technology in their backbones, and due to the popularity and cost reduction of optical fiber technology, this type of connector has also begun to appear in commercial and industrial bases.

Network and telecommunications connectors are designed to be easy to install, easy to dock, and very durable. These complex connectors have been improved so that end users can easily connect telephones or network switches to the network-in fact, these connectors can only be inserted into the corresponding ports in one direction, and improper connectors generally cannot be inserted. Mismatched ports.
Network and telecom attenuator

Attenuators are devices designed to reduce signal strength without causing interference to signal quality. These devices can also achieve more accurate impedance matching. Their application is very simple, can provide stable and reliable signal transmission for the line, is a device that modern telecommunication technology is very dependent on.

Due to the popularization and cost reduction of optical fiber technology, optical fiber connectors began to appear in commercial and industrial bases
MMJ connector

Modular jack (MMJ) connector is a type of 6-position 6-pin modular connector. As mentioned above, their appearance is almost the same as that of the RJ connector, but its hook-type latch position is on the upper side of the socket, which is a clear difference from the general 6P6C connector that is located in the middle of the socket. . These jacks are usually used to connect small computers and peripherals. Also because of the difference in latch positions, they are not compatible with general 6P6C connectors.
