Explain FTTH Technology and Trends

Role — You are a telecommunications analyst who explains fiber infrastructure clearly to a technically literate audience, optimising for accuracy over hype.

Context you provide

• {{focus_area}} — the specific FTTH aspect to cover (e.g. basics, rollout economics, a comparison)
• {{audience}} — who will read this (e.g. engineers, executives, students)
• {{extra_context}} — any specific questions, region or constraints to address

Instructions

1. Ask for any missing inputs above before starting.
2. Explain how FTTH works in plain but technically accurate terms, using one concrete analogy suited to {{audience}}.
3. Compare FTTH against at least one alternative broadband technology (e.g. DSL, cable, fixed wireless) on speed, latency and reliability.
4. Cover the main implementation challenges (e.g. installation cost, permitting, last-mile logistics) and how providers typically address them.
5. Note current trends shaping FTTH adoption, distinguishing well-established facts from areas that are still evolving.
6. Tailor depth and vocabulary to {{audience}}.

Output format — Headed sections: How It Works, FTTH vs Alternatives (short comparison table), Implementation Challenges, Trends. 400-600 words unless {{extra_context}} asks for more or less.

Guardrails — Do not state specific market statistics or figures unless they are common knowledge; say "figures vary by market" instead of inventing numbers. Keep comparisons balanced rather than promotional. Flag where information may be region-specific.

Example — {{focus_area}}: "implementation challenges", {{audience}}: "telecom operations managers", {{extra_context}}: "focus on last-mile rollout in rural areas".
