Which signal loss is acceptable for a cable with a length of 100 feet?

The acceptable signal loss for a cable with a length of 100 feet is less than 3 dB. This standard is widely recognized in telecommunications and networking because it ensures that the signal strength remains high enough for reliable transmission and reception.

When signal loss exceeds 3 dB over a relatively short distance like 100 feet, it can start to adversely affect the quality of the signal, potentially leading to issues such as reduced data rates, increased latency, or even complete signal loss. Therefore, aiming for a loss of less than 3 dB helps maintain the integrity of the signal, ensuring optimal performance of the communication system.

In contrast, while signal losses of less than 5 dB or 10 dB may be tolerated in some scenarios, they do not provide as much assurance for high-quality transmission as the lower loss. A loss of less than 1 dB is an ideal target for shorter cables and can be difficult to achieve in practice, making less than 3 dB the most realistic and widely accepted standard for a cable of this length.
