3
Splice the fiber you are installing to the fiber that is provided from the bottom of
the SC connectors on the fiber tray.
4
Secure the splice and excess fiber in a fiber splice tray (purchased separately) and
attach the splice tray to the fiber tray at the splice tray retaining point.
Note
The ends of all fiber connectors are delivered clean, polished, and
protected. When handling them during connection take care to not touch,
contaminate, or damage the fiber ends.
If the fiber ends must be cleaned or restored, it should be done in accordance
with the following specifications.
–
GR - 326 (Reliability requirements for single mode fiber optic connectors)
–
EIA/TIA 455 specifications:
13A (insertion)
34 (optical insertion loss)
171 (optical reflectance)
–
Lucent specification X-21329
5
Remove the fiber jumper from its plastic bag. Remove dust covers from the top of
the SC connectors on the fiber tray. Insert the SC connector on one end of the
fiber jumper into the SC mating sleeve on the fiber tray.
6
Run the fiber jumper through the guides on the right side of the card cage and
insert the LC connector on this jumper into the connector on module in the COP
slot.
7
Slide the fiber tray back into the chassis and tighten the retaining screw.
Routing the cables out of the enclosure
Cables are routed differently, depending on the way in which the enclosure is
mounted. Routing information for pole mounting and cabinet mounting are
described here. Local conditions should be taken into consideration, and local
procedures should be followed when using the predeclares described here, or when
mounting the enclosure in other situations.
Routing the cables for cabinet mounting
The Stinger CR unit has three outside plant cables that must be routed into the
cabinet from the three sets of protection blocks in the chassis. These cables are
approximately 25 feet in length, and end in stubs. They pass through the three 1 inch
(25.4mm) weather tight connectors installed in the 1 5/16 inch holes in the cabinet.
The optical cables, and the cables for power and ground pass through the three
3/4-inch (19mm) weather tight connectors installed in 1 1/8 inch the holes. Specific
information about cable pairs, binders, and their relationship to the circuits from the
Stinger LPMs is described in Appendix C, “Cables and Connectors.”
1
Place a 1 inch (25.4mm) weather-tight compression fitting, along with its
associated flat nylon washer and rubber bushing, on each of the outside plant
cables.
2
Place 3/4 inch (19mm) weather-tight compression fittings, along with their
associated flat nylon washer and rubber bushing, on the fiber, power, and ground
cables.
