Is the optical distribution box filled with ODF

An optical distribution box is not the same as an ODF; while both manage fiber connections, an ODF is a larger, centralized frame for high-density fiber management, whereas a distribution box is a smaller, localized enclosure for splitting and routing fibers. Optical Distribution Frame (ODF)An Optical Distribution Frame (ODF) is a central hub in fiber optic networks, designed for high-density fiber management, splicing, termination, patching, and cable protection.

OD

Fs are typically installed in data centers, telecom central offices, or enterprise network rooms and can handle hundreds of fibers. They provide structured environments for: Splicing management with splice traysFiber termination using LC/SC/MPO adapter panelsCable routing and slack managementProtection and reliability for long-term network stability ODFs are modular, scalable, and often rack-mounted, making them suitable for large-scale fiber deployments.

Optical Distribution Box

A fiber optic distribution box is a smaller enclosure, usually deployed closer to the end-user or within building corridors, stairways, or residential areas. Its primary functions include: Distributing fiber from feeder cables to multiple subscriber access pointsProviding storage for fiber slack and splicesOffering mechanical support to prevent bending or tensile stressHousing a limited number of fiber connectors (typically 1–12 fibers) Distribution boxes are compact, designed for indoor or near-user deployment, and serve as intermediate nodes in FTTH (Fiber to the Home) networks.

They complement each other in a fiber network but are not interchangeable.
