Why is it crucial to leave a service loop at both ends of a cable run during structured cabling installation?

Leaving a service loop at both ends of a cable run is essential primarily because it allows for additional length that can be utilized for future reconnections or changes. In structured cabling installations, flexibility is key to accommodating potential modifications that may arise as network requirements evolve. For example, if a device is relocated or upgraded, having extra cable length readily available can facilitate these changes without the need for completely new cabling installations.

This practice not only saves time and resources but also minimizes disruptions within the network infrastructure. By planning for future adjustments with service loops, technicians can easily access the necessary cable length while maintaining a tidy installation. Such proactive measures ensure that the network can adapt to new technologies or increases in business needs without extensive additional labor or cost.
