Installation Manual

1. Overview

1.1. Product Usage

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.

1.2. Operating Principle

1.3. Structural Features

  • 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.

5. Fault Analysis and Troubleshooting

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  

6. Packaging, Transportation and Storage

6.1 Packaging

In DA-ODF-Unit of products are packed in cartons. Products (including accessories) are packed according to packaging specifications and are damp-proof and shock proof. Accessories and spare parts are placed into respective bags and then placed in the packing box.

6.2 Transportation

After being packed in wooden boxes/cartons, DA-ODF-Unit products can be transported by motor vehicle, train, ship, or airplane. Prevent the products from collision, falling, rain, snow and direct sunshine during transportation.

6.3 Storage

The DA-ODF-Unit products should be stored in a dry and ventilated warehouse without any erosive gases. The storage temperature should be -25ºC ~ +55ºC.
