Which of the following solutions is more suitable for broadband speed-up in buildings with existing broadcast and television coaxial cables, such as convenient hotels and school dormitories?…

Question

Options

• AFTTH
• BFTTH
• CD-CMTS
• DEOC

• A
  6% (1)
• B
  19% (3)
• C
  75% (12)

Explanation

Options C (D-CMTS) and D (EOC) are correct because both technologies are specifically designed to deliver broadband over existing coaxial cable infrastructure - exactly what's already in place in hotels and dormitories wired for cable TV. EOC (Ethernet over Coax) encapsulates Ethernet signals over coaxial cable, while D-CMTS (Digital Cable Modem Termination System) is the head-end equipment that enables DOCSIS-based internet delivery over the same coax plant, making both ideal retrofits requiring no new wiring.

Options A and B (both listed as FTTH - Fiber to the Home) are wrong because FTTH requires running new fiber optic cables all the way to each room or unit, which defeats the stated goal of leveraging the coaxial cables that are already installed; it would be costly and disruptive in existing buildings.

Memory tip: Focus on the word "existing coaxial" in the question - if the technology name or acronym references coax (EOC = Ethernet over Coax) or cable modems (CMTS = Cable Modem Termination System), it's a coax-compatible solution. FTTH contains "Fiber," which signals a complete infrastructure replacement - wrong tool for the job.
