The high-voltage protection systems in cabinet is made up of fixed board, protective device of stripping cable, throat button, grounding copper line, strength core and armor layer. Fixing the strengthen core of fiber and armor layer on fixed board with throat button and protective device of stripping cable, then Series up the fiber fixed board with wire and the earth lead cross-section is not less than 35 mm2. Finally, linking to ground copper row with earth lead , the cross-section of wire is more than 6 mm2
The protective grounding of cabinet is linked from the cabinet’s top or floor to earth lead copper row, the earth lead cross-section is not less than 35 mm2.
Note: This grounding belongs to frame of open architecture; the other semi-closed frames adopt such a grounding mode. Its position is shown in the location in figure or near the location in figure. If not clear, please contact me.

If two or several racks are combined, remove the side panels of adjacent two racks and connect adjacent columns with bolts. If cables are led into the DA-ODF-960 from the bottom of the rack, it is necessary to lead the cables to the switching position of the inlet box and the lower two termination units
1. Select Φ2 mm or Φ3 mm patch cord. As shown in Figure 4-1;
Figure 4-1 Select patch cord
Insert one end of patch cord into adapter; insert the other end to corresponding adaptor after coiling of ring.
2. It may be connected directly or cross-connect.
3. Repeat steps 2, 3 to complete the patch cord operation, finally marking the finished patch cord record (Figure 4-2).

| 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 |
