Can the pass through connector be used for telephone lines?

Pass through connectors can be used for telephone line connections, especially when extending, repairing, or transferring telephone lines. Below is a detailed breakdown of its usage:

1. Applicable types of straight through connectors
The commonly used straight through connector for telephone lines is the RJ11 straight through connector, which is a connection device between two RJ11 female heads.
Usually used to connect two telephone lines with RJ11 crystal heads for extension or signal transmission.

2. Main functions
Extension cable: Connect two telephone lines into a longer cable, suitable for situations where the distance between the telephone and the socket is far.
Fault repair: When a certain section of the telephone line is damaged, the damaged section can be cut off and two new interfaces can be connected using a straight connector.
Multiple devices connected in series: Some telephone networks or device wiring may require multiple terminals to share a cable, and pass through connectors can assist in achieving this.

3. Easy installation
Insert the RJ11 telephone lines at both ends pass throughly into the sockets on both sides of the pass through connector, without the need for soldering or specialized tools.
Belonging to plug and play components, suitable for use in both home and office environments.

4. Does not affect signal quality (provided that the quality is qualified)
The high-quality RJ11 straight connector has extremely low insertion loss and almost no attenuation for voice signals.
But if the connector quality is poor or the plug contact is poor, it may cause noise, unstable signals, or disconnected calls.

5. Scope of application
Fixed line telephone, fax machine, ADSL line splitter connection, home telephone wiring expansion, and other occasions.
It is most widely used in analog telephone systems.

6. Precautions
Interface matching: Telephone lines generally use RJ11 or RJ12, and it is necessary to ensure that the plug and connector interface types are consistent when using them.
Wire arrangement: Ensure that the metal plates inside the connector are accurately aligned with the metal terminals of the telephone line, otherwise normal communication may not be possible.
Environmental adaptability: If used outdoors or in humid environments, models with protective shells or good sealing performance should be selected.
