Field Cabinet and Hardware Preparation
Complete the following steps prior to starting cable splicing:
1. Use the special hex key to unlatch and open the field cabinet door.
2. Use a screwdriver to loosen (do not remove) the screws that secure the splice chamber cover; then remove
the cover and set it aside.
3. Locate the 710-connector caps that are bagged and tied to the tie bars in the splice chamber and place them
aside.
The field cabinet cables are secured to the tie bars on the rear wall of the splice chamber. The OSP cables,
including the fiber cables, should have been pulled into the field cabinet and temporarily secured in the
splice chamber. The cable labeling for each specific field cabinet is detailed on a decal on the inside of the
door.
Prior to splicing, the cable ports must be properly sealed and each OSP cable grounded to the field cabinet
ground bus.
4. Pull the unsheathed portion of the OSP cables out of the splicing chamber.
5. Remove all cable ties securing the field cabinet cables to the tie bars and pull the field cabinet's cable tails
out of the splicing chamber.
6. Secure an 890-type splicing tool to a butt box in the front of the splicing chamber.
It is recommended that the digital pairs be spliced before the HDSL and miscellaneous pairs.
7. Mark the OSP pairs to be spliced. The field cabinet pairs are factory marked using the following
nomenclature:
Sheath Identification*
A(x-y)
B(x-y)
C(x-y)
D(x-y)
* The (x-y) refers to the first and last pairs used in the particular sheath.
8. When splicing, ensure that the field cabinet pairs to be spliced are routed over previously spliced cables and
under any unspliced cables (to prevent tangling).
