One is Baseband and the other is Broadband cable. Coaxial cables are categorized based on the type of signal transmission.
There are many types of coaxial cable connectors.įour are common. Common impedances are 50 ohms, 75 ohms, 95 ohms. Coaxial cables are rated in ohms for their impedance. Purposeīoth inner conductor and braided wire mesh conductor is in the cable share a common central axial, hence the term coaxial. Since the receiver takes only the difference between the two wires the effective noise is canceled.Īs the name implies, Shielded twisted pair cable adds a conductive layer (typically a metal foil or a mesh) surrounding either each pair or entire cable. The significance of twisting is it reduces or nullifies the interference such as noise or cross talk caused due to radiofrequency of electromagnetic interference.īy twisting the wires, the effect of noise or disturbance is the same on both wires. More twists per foot in a pair of wires, less the cross talk. The number of pairs varies depending on the cable type. Every two wires are twisted around each other to form pairs that are encased in a plastic sheath each wire with a diameter of 0.4 mm to 0.8 mm. Twisted pair cables consist of color-coded pairs of insulated copper wires, one wire carries the signal, and the other is used for ground reference.
