A front-access, open-frame optical distribution frame (ODF) for structured fiber patching or combined patching and splicing. Dedicated routing paths organize patch cords and slack while keeping the distribution interface accessible from the front.
In dense optical distribution areas, the frame must accommodate patching work, routing transitions and service loops without turning routine changes into cable-management problems.
Incoming fibers, patch cords and excess slack compete for space. When routing is not planned as a system, access and tracing become harder during installation or reconfiguration.
Front-access distribution combines vertical management, an upper cable drop, side-entry routes and a bottom transfer duct for connections within and between frames.
Five documented design elements describe how the ODF handles entry, distribution, access and cross-frame routing.
Provides an upper cable path and a bend-conscious drop into the frame.
Routes patch cords along the frame; the side duct includes rear and side openings for cable entry and access.
Supports patch-only or patch-and-splice arrangements using specified drawer accessories.
Allows patch cords to pass between frame sides or across adjoining frames in side-by-side and back-to-back arrangements.
An adjustable upper bracket supports planned wall or back-to-back rack mounting configurations.
Published frame heights, 3U drawer quantities and fiber capacities from the supplied product datasheet.
| Frame height | Overall height | 3U drawers | Fiber capacity listed |
|---|---|---|---|
| 22U | 1.2 m | 6 | Up to 864 fibers |
| 42U | 2.2 m | 12 | Up to 1,728 fibers |
| 58U | 2.6 m | 16 | Up to 2,304 fibers |
Capacities are reproduced from the December 2015 datasheet and depend on the selected drawer/connection arrangement. Confirm the required fiber count and bill of materials before ordering.
The frame is suited to projects in which front-access optical distribution and organized cross-connect routing are part of the installation design.
Organize front-facing connection panels and patch-cord paths for fiber distribution.
Plan splice-and-patch drawers in a common frame with defined slack handling.
Use specified bridge and lower transfer routes where adjacent distribution frames must interconnect.
The manufacturer’s ordering syntax combines the frame-height code with the vertical cable-management option.
