Installation Manual
1. Overview
Dawnergy’s DA-ODF unit are designed and manufactured according to
the international standard and implement such functions as the
inlet, fixation, and stripping protection for optical cables,
protection for optical fibers storage and management of fiber patch
cord, fixed connection and cross connection of optical fibers.
Meanwhile, value-added modules such as optical splitter and
wavelength division multiplexer can be installed if required by the
customer. They can find wide application in optical fiber
communication networks and are applicable to central offices and
cross-connecting points in an optical access network.
- Full front operation for optical fiber distribution and
dispatching;
- 19’’ installation of racks;
- Suitable for ribbon or non-ribbon cables;
- Adapter insertion installation, suitable for multiple adapters such
as SC.
- Adapters can be installed in an angle of 30 degrees to the front to
the cabinet to prevent direct arc light from hurting your eyes and
to facilitate cabling.
- Ribbon cables provide dedicated stripping protection connector to
make the protection of bare fibers and the fixation and grounding
of optical cables more perfect and reliable.
- The 48-core ODF unit 2U with SC/UPC.

Step 1: ODF Unit Installation and fixation on the rack.
Step 2:Open the front door. Pull out the rotating disc from the
unit.
Step 3: Lead the patchcord enters the ODF unit and connect to the
adapters.
- Input patchcord
Step 4: Connect and arrange the output patchcord.
- Output Patchcord
Step 5: Push in the rotating disc from the unit and close the front
door.
| Serial | Common Fault | Cause Analysis | Troubleshooting and | Remarks |
| 1 | Disconnection of transmission line or poor transmission effect | Inappropriate bending radius causes permanent physical deformation
to the optical cable/fiber and increases transmission loss | During construction, the engineering personnel must pay attention
to the protection of bending radius of fibers (bends and
bottlenecks for cable inlet and outlet in racks) and ensure that
the cable routing is reasonable | |
| Loose connection, great loss of optical fiber active connectors
(adapters, pigtails/fiber patch cord) | Check whether all threaded or plug-in mechanical connectors are
firm and meet their respective standards | |
| 2 | Optical fibers are easy to fall off or not reliable | The most fragile part of the optical fiber/cable lies in the
position where abrupt physical structure change happens, which may
affect the security and reliability of the entire network | Be careful in cable fixing, stripping protection, secure grounding,
and splicing point protection; no error or omission is allowed.
| |
| 3 | Redundant fiber storage disorder | Caused by insufficient cable length in design or careless work of
construction personnel | Sufficient fiber core shall be reserved during product planning.
Adjust cables during construction to make cables in the rack clear
and neat. | |
| 4 | Unclear labels | Disorder caused by the dismantle during construction or maintenance | Clear labeling and detailed records | |
