1. FTTB (Fiber to the Building)
Definition: Fiber is extended to a building’s telecom room or basement, but the final connection to individual users is via copper cables (Ethernet/VDSL) or WiFi.
Use Case:
Common in apartment complexes, offices, and multi-dwelling units (MDUs).
ISPs deploy fiber to the building’s distribution point, then use existing copper wiring for last-meter connectivity.
Pros:
1. Lower cost than FTTH (since fiber doesn’t go to every room).
2. Faster deployment in dense urban areas.
Cons:
1. Limited bandwidth compared to full FTTH (due to copper bottleneck).
2. Higher latency than pure fiber.
2. FTTH (Fiber to the Home)
Definition: Fiber runs directly to each home or apartment, terminating at an optical network terminal (ONT) inside the residence.
Used in residential broadband, IPTV, and high-speed internet.
Common in new housing developments and modern ISPs.
Pros:
1. Ultra-high speeds (1Gbps–10Gbps+).
2. Low latency, future-proof for 5G/8K/VR.
3. More reliable than copper-based networks.
Cons:
1. Higher deployment cost (requires fiber to every unit).
2. Labor-intensive installation in old buildings.
3. FTTR (Fiber to the Room)
Definition: Fiber is extended not just to the home but to every room, replacing traditional Ethernet/WiFi backhaul.
Use Case:
Used in smart homes, enterprises, and high-bandwidth applications.
Requires an optical modem in each room (e.g., Huawei’s FTTR solution).
Pros:
1. Gigabit+ speeds in every room (no WiFi dead zones).
2. Future-proof for 8K streaming, cloud gaming, and IoT.
3. More stable than WiFi mesh networks.
Cons:
1. Very expensive (fiber wiring inside walls).
2. Requires professional installation.
