The product being described is a type of network cable that is designed for high-speed data transmission. The cable has the following features: 23Awg solid bare copper conductor: This refers to the size and material of the wires inside the cable. The 23Awg size indicates that the wires are relatively thick, which can help to reduce signal loss over long distances. The bare copper material provides good conductivity for transmitting signals. PE insulation: This refers to the material that is used to insulate the individual wires inside the cable. PE (polyethylene) is a common insulation material that provides good electrical properties and is resistant to moisture and other environmental factors. 4pair, FR PVC/LSZH jacket: This refers to the overall structure of the cable. It has four pairs of wires, which are twisted together to reduce interference and crosstalk. The jacket is made of either FR PVC (flame-retardant polyvinyl chloride) or LSZH (low-smoke zero-halogen), which are both materials that meet safety standards for use in industrial and commercial environments. RoHS compliant: This refers to compliance with the European Unions Restriction of Hazardous Substances directive, which restricts the use of certain hazardous materials in electronic products. Frequency: 250Mhz: This refers to the maximum frequency that the cable is designed to transmit. A higher frequency means that the cable can support faster data transfer rates. Transmission: 155mMps: This refers to the maximum data transfer rate that the cable is designed to support. A higher data transfer rate means that the cable can transmit more data in a given amount of time. Industrial standard: International ISO/IEC-1180 USA ANSI/ANATEL, TIA/EIA-568b.2-2001, UI CE approved: This refers to the various industry standards that the cable meets, which ensures that it is compatible with a wide range of networking equipment and can be used in different countries and regions. Applications: This refers to the different types of networks that the cable is designed to support. ISDN, 10Base-T, 100Base-T, ATM 155Mbps, 100Vg-anylan, Token ring, and TP-PDM are all different network protocols that the cable can be used with. Product performance: This section provides specific performance characteristics of the cable. Linear resistance refers to the amount of electrical resistance in the cable, which can affect signal strength. Mutual capacity refers to the amount of capacitance between adjacent wires in the cable, which can affect signal integrity. Unbalance capacity refers to the amount of capacitance imbalance between the wires in the cable, which can affect signal quality. Characteristic impedance refers to the impedance of the cable, which must match the impedance of the network equipment for optimal performance. Velocity of propagation refers to the speed at which signals travel through the cable, which can affect the timing of data transmissions.
