3. Fiber Optic Distribution Hubs (FDHs):

   - Characteristics: Weather-resistant cabinets, modular design for scalability, support for high-density fiber management, secure access points for technicians, and integration of splitter modules for PON (Passive Optical Network) deployment.

   - Use: Centralized points for distributing and managing fiber optic connections in FTTH (Fiber to the Home) networks.

4. Fiber Optic Terminal Boxes:

   - Characteristics: Compact, weatherproof enclosures, support for fiber termination, splicing, and patching, various mounting options (pole-mounted, wall-mounted), and easy access for technicians.

   - Use: Termination points for fiber optic cables in outdoor environments, facilitating connections to end-user premises.

5. Optical Network Terminals (ONTs):

   - Characteristics: Weatherproof enclosures, multiple service interfaces (Ethernet, Wi-Fi, voice), support for high-speed data rates, robust security features, and remote management capabilities.

   - Use: Terminate fiber optic cables at the customer's premises, converting optical signals into electrical signals for end-user devices.

6. Optical Line Terminals (OLTs):

   - Characteristics: High-capacity, rack-mounted devices, support for multiple PON architectures (GPON, EPON), advanced traffic management and quality of service (QoS) features, integration with network management systems.

   - Use: Centralized control and distribution of fiber optic signals in PON networks, connecting to multiple ONTs.

7. Fiber Optic Splitters:

   - Characteristics: Passive devices, various split ratios (e.g., 1:2, 1:32), low insertion loss, compact and robust packaging, and temperature-resistant.

   - Use: Divide a single optical signal into multiple signals for distribution in PON networks.

8. Weatherproof Fiber Optic Connectors and Adapters:

   - Characteristics: Ruggedized, waterproof and dustproof designs, easy to install and disconnect, high performance with low insertion loss, support for various connector types (SC, LC, ST).

   - Use: Ensure reliable and secure connections in outdoor fiber optic networks.

9. Remote Radio Heads (RRHs):

   - Characteristics: Weatherproof enclosures, high power efficiency, support for multiple frequency bands, fiber optic interface for connection to baseband units (BBUs), and advanced antenna technologies (e.g., MIMO).

   - Use: Enhance cellular network performance by providing closer proximity to users, commonly used in LTE and 5G networks.
