What is the future of communication cable, Copper or Fiber?

Some of the CAT8 cable is now being offered in the market. At present, it’s expected that it will support bandwidths of up to 2 GHz (2000 MHz) and speeds of 25Gbps / 40Gbps for about 30 meters of cable at most. Due to the fact that it is only effective at short lengths, it’s primarily intended for use as patch cords in data centers. However, it may end up being used for other purposes in the future.

Will copper ever be completely replaced by fiber, is a question that has been frequently asked in recent years. Yet, maybe we should also ask if copper actually needs to be replaced?
It’s obvious that fiber optic (FO) cable has numbers of easily-identifiable advantages over copper cable. Fiber optic delivers greater bandwidth. FO can move data greater distances at much higher speeds than copper. FO cable is also capable of carrying more information, with less energy loss, than copper wire.

However, as we all know, copper isn’t completely useless. It supports Power Over Ethernet (POE), meaning a single network cable can be used to provide both data connection and electric power. POE is great in CCTV systems that use cameras on a long run, especially IP cameras that is far away from an accessible power source. The only alternative to this is powered fiber, which combines a fiber cable with a copper power cable.

Whether to use copper or fiber also depends upon how long the cable runs. In horizontal cabling, the runs are likely to be relatively short. For instances such as these, it will take a long time before copper is replaced by fiber. In horizontal cabling situations, FO can certainly be used. However, fiber is generally only used when interference, either electromagnetic (EMI) or radio-frequency (RFI) is a problem, or when security is a critical concern.
So, in a nutshell, it looks like Cat8 cable will see some use. It’s important to note however, that there are two standards for Cat8, Category 8.1 and Category 8.2, and the latest technical information is that Category 8 is likely to allow other connector types (such as ARJ45) as well as the RJ45. ARJ45 connectors are essentially augmented RJ45s, and deliver faster performance than standard RJ45 connectors, making them much more suited for high-frequency applications.
Copper connectors are generally cheaper than fiber connectors, and with most end users finding that traditional copper-based category cables coupled with Wi-Fi are more than adequate for their needs, fiber is unlikely to completely replace copper anytime soon.
