Installation Manual
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 splicing, 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.

Remarks |
| DA-ODU48-SC-S | ODF Unit | 2U×480×260 | Splicing Type |
Insulation resistance between grounding device and cabinet ＞ 2x104MΩ/500V(DC)
Withstanding voltage between grounding device and cabinet no less than 3000V(DC)/1min, no breakdown, no flying arc.
Step 1: ODF Unit Installation and fixation on the rack.
Step 2:Open the front door. Pull out the rotating disc from the unit, and open the splice tray.
Step 3: Strip the optical cable for about 1.0 meters, and then the optical fiber cable enters the ODF unit.
1,Cable 2,Splice tray
Step 4: Lead the stripped optical cable and pigtail into both ends of the splice tray, splicing the fiber using the heat shrink tube, and fix it in the slot.
Step 5: Test the fiber by VFL, after the test, arrange the optical fiber cable, and connect the patchcord.

Step 6: 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 |
