The capacity of the optical distribution box is less than

Optical distribution boxes with lower capacity typically support between 2 and 24 fibers, suitable for small-scale FTTH or FTTx deployments.

Low-Capacity ODB Models

• 2 to 12 fibers: Small ODBs, such as the LW-ODB-2D, LW-ODB-8D, and LW-ODB-12A/B, are designed for minimal subscriber connections, often serving 2–12 endpoints. These boxes provide basic fiber management, including splice trays and adapter ports, and are ideal for indoor wall mounting or small outdoor installations .
• 24 fibers: The ODB-24 or LW-ODB-24D can terminate up to 12 fibers and house PLC splitters with ratios up to 1:8. These are compact, wall-mountable enclosures suitable for building entry points or small FTTx networks .
• 8 subscribers: The PPC ODB Series 100A is an example of a low-capacity outdoor-rated box supporting up to 8 subscribers, with space for 10 mechanical or fusion splices, one PLC splitter, and one or two SC duplex or LC quad adapters .

Key Considerations

• Splice and adapter capacity: Even low-capacity boxes include splice trays and adapter panels, but the number of fibers and splitters is limited. Planning should account for future expansion, as small boxes may quickly reach their maximum capacity .
• Deployment scenarios: Low-capacity ODBs are ideal for single-dwelling units, small multi-dwelling units, or areas with limited subscriber density. They are generally lighter, easier to install, and cost-effective for small-scale networks .
• Future scalability: It is recommended to reserve 20–30% headroom in fiber ports to accommodate network growth without immediate replacement . In summary, optical distribution boxes with capacities less than 24 fibers are suitable for small-scale FTTH or FTTx applications, providing essential fiber management while limiting the number of subscribers and splices they can accommodate .
