I treat 100 meters (328 ft) as the Cat 5 design limit for a standards-compliant channel: 90 m permanent link plus up to 10 m of patch cords. Longer pulls may “link,” but attenuation, crosstalk, retries, and PoE voltage drop rise fast. Local area networks (LANs) have historically been designed in a way that ensures all end devices are within 100 meters (m) of a telecommunications room (TRs) to comply with industry cabling standards. Now with the adoption of smart building technologies, more devices than ever are being connected. 100 m Fiber Optic Cables are available at Mouser Electronics. If I need >100 m, I add a repeater or go fiber—and certify the. Fiber optic cable transmission distance is determined by two primary physical factors that affect signal quality as light travels through the fiber medium. The greater the distance, the greater.
