What are Telecom Connectors?
Telecom connectors are a type of Insulation Displacement Connector. They can connect multiple wires quickly without the need for special tools. You simply squish a colored cap onto the wire ends and you're done! Telecom connectors are generally designed for smaller wire sizes. There are many types of telecom connectors, including Coaxial PCB connectors, Telephone jacks, Compression terminal lugs, and Fiber optic connectors.
Types of Telecom Connectors:
Coaxial PCB connectors:
If you're looking for high-quality coaxial connectors for your next telecom or datacom project, you've come to the right place. Advanced Interconnections' Mezza-pede(r) SMT Connectors offer the long-lasting, high-reliability performance you need. They have undergone a 20-day mixed-flowing-gas test to ensure reliable performance. Plus, they feature a heavy gold-plated lead frame for added durability and reliability. Plus, these connectors feature an overmolded lead frame, which seals the surface-mount leads and prevents wicking of the solder joints.
SV Microwave's complete line of coaxial PCB connectors meets the requirements of the telecom industry. These connectors offer high-density applications while maintaining the highest performance. They are available in single-port and multi-port configurations, with 2.92 mm and 1.85 mm insertion widths. In addition, SV Microwave's SMPx PCB connectors support radial and axial misalignment.
Molex Multi-Port RF (MPRF) Cable-to-Board Connectors are designed for space-constrained RF applications. They also feature high density in a compact package, while allowing insertion and removal with ease. In addition, these connectors are rugged and can withstand high-vibration environments. Molex offers four, six, and eight-port versions of the MPRF connector.
Telephone Jack:
There are several different types of telephone jack for telecom connectors, each with their own specific features. Most commonly, they use the RJ11 connector, which is a modular connector with four conductors for one telephone line. These are used for single-line telephones in countries other than the United States and may be labeled 6P4C to allow for an additional wire pair for lamps. Other jack types include the RJ14, which is used for two lines, the RJ25, which is used for three lines, and the RJ61, which is similar but uses an 8P8C connector for four lines.The earliest versions of telephone jacks for telecom connectors were bulky and inconvenient, and subsequently replaced them with more compact and less expensive modular connectors.
To install a new jack for telecom connectors, you must unscrew the jack cover. Some jacks are secured with screws, while others are held in place by self-adhesive strips. Screws are recommended for phone jacks that do not have self-adhesive strips. Once the new jack is installed, you must make the necessary wiring connections. If you have a telephone cable, make sure that the insulation touching the terminal screw touches the wire's insulating surface.
The insert of the jack has an additional opening for positioning the gel. The front opening receives the plug. The rear opening is also larger. The insert is placed in the rear opening. The housing is threaded, and the jack is positioned lower than in the conventional jack. A retainer binds the insert to the housing, and limits its translational movement. While a standard telephone jack is also preferred, some jacks are still preferred.
Compression Terminal Lugs:
A compression lug is a type of connection that makes a tight seal. Compression terminal lugs are made from copper or aluminum and are suited for telecom, power, OEM, and military applications. The lugs feature a color-coded crimping system that ensures that the correct lug is used for the right application. The crimping die produces circumferential compression and hex or diamond-shaped compression that exceeds the IEC 61238-1 standard. The long barrel also provides extra crimping assurance and ensures proper cable connection for heavy-duty loads.
Compression terminal lugs are part of a system called the Burndy Engineered System. They are used to terminate telecommunication dc cable ends for central office installations. The Burndy Break-Away HYLUG(tm) compression terminal is certified to ensure dependable connections and are marked with the die index number. The UL-listed and CSA-certified Burndy Compression Lug is a reliable and permanent connection solution.
Fiber Optic Connectors:
The growing demand for high-speed Internet access and high-quality cable connectivity are two major drivers for the market. In addition to these factors, fiber optic connectors also provide effective protection for optic fiber. Furthermore, they play a vital role in augmenting the market growth in the coming years. Recent advancements in telecommunication technology and the launch of 5G communication systems are also fueling the growth of this market. Further, the population is increasingly shifting towards digital platforms and online services. Hence, the market for fiber optic connectors is expected to expand further.
Although more common in datacoms, fiber optic connectors are also increasingly used for FTTH applications. In FTTH networks, they are useful for high-density patching, quick deployment of aggregate fibers, and smaller nodes and ODFs. Though their role in telecommunications networks is primarily passive, choosing the right connector can result in significant cost and speed benefits. For more information, read on to learn about the various fiber optic connectors used in telecommunications.
While single-mode optical fiber is small-core, it has multiple wavelengths. To transmit data, light must follow the same path through the fiber. To accomplish this, a splice is required to join two fibers. Splices can be either temporary or permanent. Two types of connectors are available for telecoms: the ST connector and the UPC connector. The former is thin, convex, and uses ceramic ferrules.
Selection Criteria for Optic Connectors:
When it comes to optic connectors, it's important to consider the occultation of light in these devices. Metal particles, such as dust, can clog the connectors. Also, human oils and other materials can contaminate the fibers. Therefore, fiber optic connectors need to be regularly cleaned to keep their efficacy intact. Cleaning them is not a difficult task and will restore their effectiveness.
Telephone Line to Phone Cord:
A telephone line to phone cord is a common connection between two appliances. Known as a wall jack, it's the most standardized connection of all. It serves as the demarcation point between the individual's phone and the telephone network. In addition, all wall jacks in a home form part of the house's internal wiring. The telephone cord from a telephone set base is less regulated and typically uses a 4P4C connector.
The wiring on a telephone outlet consists of twisted pairs of copper wire. A telephone outlet usually has one, two, or three pairs of wires. Most cables used today are UTP (unshielded twisted pair), but some may still need to connect to an old-fashioned "quad" cable. The two center pins of a telephone are used for the dial tone circuit, while the other two are used for the talk circuit.
A telephone line to phone cord can also have a modular test jack for the caller to check the liveness of the line. It can be connected to a terminal strip for internal telephone wire. If the wires touch each other, a short circuit will prevent the call. To prevent a short circuit, you must separate the wires and re-install them properly. Once the wiring is correctly re-attached, the phone should continue working normally.
Selection Criteria for Line to Phone Cord:
When choosing a telephone line to phone cord, the first thing to do is determine the number of telephone lines you need. You may have a few lines at your home and need a connector for each line. This will help you avoid confusion in the future. Once you know how many lines you need, you can select the right connector. You can choose a jack with the correct number of pins and use the modular connector.
