Which of the following is NOT a design consideration for broadband video distribution?
The correct answer is B. Adhering to the 90 meter (295 feet) rule for horizontal distribution. The 90-meter (295-foot) horizontal cable run limit is a structured cabling standard defined for data networks (e.g., TIA-568), specifically governing Ethernet/LAN installations. It does NOT apply to broadband video distribution systems. Broadband video distribution (such as…

Explanation
The 90-meter (295-foot) horizontal cable run limit is a structured cabling standard defined for data networks (e.g., TIA-568), specifically governing Ethernet/LAN installations. It does NOT apply to broadband video distribution systems. Broadband video distribution (such as CATV/RF systems) has its own set of design constraints: amplifier link budgets (A) ensure adequate signal strength across the network, amplifier cascade limitations (C) restrict how many amplifiers can be chained before signal quality degrades, environmental factors (D) like temperature and moisture affect cable and equipment performance, and drop length (E) impacts signal loss at individual subscriber connections. None of these are governed by the 90-meter rule.
