In summary, the maximum length for a UTP and STP cable segment is 100m, according to the ANSI/TIA/EIA standard. If longer runs are needed, the use of active hardware like a repeater or switch is necessary. This length allows for 90m of fixed cabling and two connectors, with two 5m patch leads at each end. For other network types, longer distances can be achieved at lower data rates.

Hi, I've read that the max length of UTP and STP cable segments is 100m? Does this mean that a repeater is required after every signle cable segment?

You didn't say it, but you must be referring to CAT-5 or similar systems?

Maximum cable segment length

According to the ANSI/TIA/EIA standard for category 5e copper cable (TIA/EIA 568-5-A[5]), the maximum length for a cable segment is 100 meters (328 feet). If longer runs are required, the use of active hardware such as a repeater or switch is necessary.[6][7] The specifications for 10BASE-T networking specify a 100 metre length between active devices.[8] This allows for 90 metres of fixed cabling, two connectors and two patch leads of 5 metres, one at each end.

For other network types, you can go much farther, but at lower data rates.
 

What is a cable segment?

A cable segment refers to a section of a cable that is used to transmit data or signals. It is typically a physical connection between two devices or components.

What is a repeater?

A repeater is a device used to amplify or regenerate a signal in order to extend the distance that the signal can travel. It receives a weak signal, amplifies it, and then re-transmits it.

Why is spacing between cable segments important?

The spacing between cable segments is important because it affects the quality and strength of the signal being transmitted. If the spacing is too short, the signal may become distorted or weakened, leading to data errors or loss.

What factors determine the optimal spacing between cable segments?

The optimal spacing between cable segments is determined by the type of cable being used, the signal strength, and the distance the signal needs to travel. Other factors such as interference and environmental conditions may also play a role.

How do I determine the appropriate spacing for my cable segments and repeaters?

The appropriate spacing for cable segments and repeaters can be determined through various methods such as signal strength measurements, simulation software, and industry standards. It is important to consult with experts or refer to technical specifications to ensure proper spacing for optimal signal transmission.
