Connectors
- A device that eliminates a section of cabling or implements a state of access for network devices, including PCs, hubs, and switches. Connectors can be famous for their physical presentation and mating features, including jacks and attachments (male connectors) or attachments and ports (female connectors).
- Connectors are used to connect the guided (wired) transmission media to devices like the hub, server, workstations etc.
RJ45 Connector:-
- RJ45 is newer, modular, self-securing and compact technology used for connecting the Ethernet cables to different electronic devices.
- The RJ45 is an 8 pin connector used to attach the Ethernet interfaces. It is known as an 8P8C connector.
Types of cables based on the termination:
- Straight-over-cable
- Crossover cable
RJ11 Connector:-
- RJ11 is used to terminate the conventional PSTN telephone networks. RJ11 is a four pins connector which is used for terminating the telephone wires.
- The RJ11 technically uses the center 2 contacts of 6 available and is used for wiring a single phone line.
- It is the common connector for plugging a telephone into the wall and the handset into the telephone.
BNC Connector:-
- Virtually any standard connector is able to carry current over a mechanical connection for DC and low-frequency AC circuits.
- Radio frequency, on the other hand, requires a connection that will minimize changes in impedance, which could generate reflection and standing waves that can cause damage.
- Coaxial cables can carry radio frequencies while maintaining a characteristic impedance.
- BNCs are constant impedance connectors they have the same characteristic impedance across the whole connection, equal to that of coaxial cables.
- This makes BNC connectors well-suited for RF applications, as RF signals traveling along a coax cable will not see any impedance changes as they pass through the BNC connector, resulting in fewer reflections and a lower level of loss.
SC-ST Connectors:-
- SC stands for subscriber connector and is a standard-duplex fiber-optic connector with a square molded plastic body and push-pull locking features. SC connectors are typically used in data communication, CATV, and telephony environments.
- ST stands for straight tip, a high-performance fiber-optic connector with round ceramic ferrules and bayonet locking features. ST connectors are more common than SC connectors.
- You can generally use SC and ST connectors with either single-mode or multi-mode fiber-optic cabling.
- Coupling receptacles for these connectors come in either panel-mount or free-handing designs. For narrow space installations, you can get 90-degree boot versions instead of straight versions.
- SC and ST connectors come in both simplex and duplex form.
