CAT8 is a twisted-pair copper cable standard that supports 25G Ethernet transmission over distances up to 30 meters. Some of the key characteristics of CAT8 for 25G application include:
1、Bandwidth: CAT8 cables are designed to support a bandwidth of up to 2 GHz, which enables them to transmit data at speeds of up to 25 Gbps.
2、Connector type: CAT8 cables typically use the RJ45 connector, which is the same connector used for previous Ethernet standards.
3、Cable construction: CAT8 cables are typically constructed with four twisted pairs of copper wires and have an overall shielding to reduce electromagnetic interference.
4、Distance limitations: CAT8 cables are designed to support a maximum transmission distance of 30 meters. This distance can be extended using signal boosters or repeaters.
5、Power delivery: CAT8 cables can deliver up to 90 watts of power, which makes them suitable for Power over Ethernet (PoE) applications.
6、Compatibility: CAT8 cables are backward compatible with previous Ethernet standards, such as CAT6 and CAT7, allowing them to be used in networks that have a mixture of different cable types.
7、Cost: CAT8 cables are generally more expensive than previous Ethernet cable standards due to their higher performance specifications and construction requirements.
