• Ancillary Equipment: Includes fiber termination boxes, distribution splitters, Category 6 (Cat6) cables, and weak-current cabinets.

4. Fiber Deployment Strategy

4.1 Fiber Installation Process

1. Entry Point: Route single- or dual-core G.657A2 drop cables from the distribution box to the household weak-current cabinet using air-blowing or conduit pulling techniques to prevent fiber bending.
2. Fiber Splicing: Employ HUALUE high-precision fusion splicers, achieving splice loss ≤0.1 dB for optimal signal integrity.
3. Termination Box Installation: Install HUALUE fiber termination boxes with SC/APC connectors in the weak-current cabinet to secure cables and interface with the ONU.
4. ONU Deployment: Install HUALUE ONU (1×10/100/1000 Mbps Ethernet, 3×10/100 Mbps Ethernet, 1×RF output, dual-band WiFi) in the weak-current cabinet, connecting to fiber and indoor cabling.

4.2 Renovated Homes: Cabling Solution

Challenge: Minimize structural disruption while ensuring aesthetic integration.
Solution:

• Fiber Entry:
  • Utilize existing weak-current or air-conditioning conduits for drop cables (diameter ≤3 mm), routed along baseboards or doorframes.
  • For conduit-free homes, deploy HUALUE transparent self-adhesive fiber channels (eco-friendly PVC) along walls or ceiling corners.
• WiFi Coverage:
  • Implement HUALUE Mesh WiFi 6 system with one primary ONU and 2–3 extension nodes, covering up to 200 m².
  • Extension nodes connect via powerline or wireless Mesh, eliminating additional wiring.
  • Optimize 2.4 GHz (long-range) and 5 GHz (high-speed) band switching, ensuring signal strength ≥-65 dBm.
• CATV Integration:
  • Connect ONU RF output to a 1:4 or 1:8 splitter via existing coaxial cables to distribute CATV signals to living rooms and bedrooms.
  • For homes without coaxial cables, use HUALUE RF extenders to transmit CATV signals over WiFi, compatible with smart TVs.
• Key Features:
  • Installation time ≤2 hours to minimize resident disruption.
  • Use HUALUE pre-terminated fiber jumpers (insertion loss ≤0.2 dB, return loss ≥60 dB) for plug-and-play deployment.

4.3 Unrenovated Homes: Cabling Solution

Advantage: Opportunity to pre-install conduits and cables for scalability and aesthetics.
Solution:

• Fiber Entry:
  • Pre-install 20 mm PVC conduits from the distribution box to the weak-current cabinet, accommodating dual-core drop cables with 2 m slack for future splicing.
  • Install HUALUE ODF distribution frames in the weak-current cabinet for multi-fiber management and ONU integration.
• WiFi Coverage:
  • Pre-install Cat6 cables (≥1 Gbps) from the weak-current cabinet to key areas (living room, bedrooms, study), connecting to HUALUE WiFi 6 Access Points (APs).
  • Each AP supports a 15 m radius with MU-MIMO technology for multi-device connectivity.
  • Deploy HUALUE AC controllers in the weak-current cabinet for centralized AP management and signal optimization.
• CATV Integration:
  • Pre-install RG6 coaxial cables from the weak-current cabinet to TV points, connected to the ONU’s RF output.
  • Use HUALUE Erbium-Doped Fiber Amplifiers (EDFA) at the central office to enable triple-play (1310 nm/1490 nm/1550 nm) for long-distance CATV transmission.
• Key Features:
  • Star topology with the weak-current cabinet as the central hub for simplified maintenance.
  • Reserve ports for future smart home devices (e.g., cameras, sensors).
