One advantage of using preconnectorized jumpers and cables is:

Preconnectorized cables are typically more expensive than field-terminated connectors due to factory manufacturing overhead, specialized equipment, and quality testing costs.

Preconnectorized jumpers have specific handling and pull tension limits to protect the factory-installed connectors; they are generally less rugged than bulk cable designed for pulling.

Factory preconnectorized cables are produced using precision machinery and calibrated test equipment under controlled environmental conditions, ensuring each termination meets defined optical performance specifications such as insertion loss and return loss. This factory certification process provides documented quality assurance and consistent performance that eliminates the variability inherent in field termination. End users receive tested, certified cables with traceable quality documentation.

Preconnectorized cables actually reduce engineering and installation time by eliminating on-site termination work, not increase it.

Preconnectorized jumpers do not eliminate the need to address water-blocking components; outdoor cables still require proper water-blocking measures regardless of connector type.
