The cable should be bent as little as possible. If the cable remains outside for more than 24h during installation protective material should be used to prevent cable. All fiber optic cables have specifications that must not be exceeded during installation to prevent irreparable damage to the cable. Fiber optic cable bend radius is a critical mechanical parameter that determines how sharply a cable can be bent without risking microbending, macrobending, signal loss, or long-term structural fatigue. The minimum bend radius defines the smallest. Segregate fiber optic cable from heavy copper cables to avoid bend radius violations and crush loads. Comply with National Electrical Code requirements for cable ratings and fire safety.

Cable color codes serve four primary functions: Live (phase) wires carry dangerous voltage. A standardized color prevents accidental contact during installation or repair. Ground wires provide a safe path for fault current —color coding ensures they're never confused with live or. The wiring color codes are the standard safety language of electricity. They make it easy to identify immediately which wires are live, neutral, or grounded (avoiding costly mistakes and hazardous accidents). These codes help us to follow the safety. Electrical cable colors play a fundamental role to maintaining safety and make the work of professionals and users themselves easier. It's not a mere question of aesthetics.
