The high-voltage protection systems
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
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.
- Two grounding must be done, otherwise, my company do not
responsible for any consequences incurred by this.
- We must ground when stripping cable.

3．6 Rack Combination Installation
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
4. Operation and maintenance
4.1. Patch cord operation
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).

6. 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 | |
