MICROCABLE UNWINDING AND ROUTING ADDITIONAL GUIDELINES
This section provides procedures for unwinding and routing microcable from the panel through
an open trough system or conduit. This is done when the lead end of the cable is paid out from
the cable spool tray (if the panel has no external spool) or from the external spool (if present).
7.1
Microcable Installed in Open Trough System
Use this procedure to route the lead end of the microcable through an open trough system:
1. Route the microcable to the appropriate ODF, fiber panel, or splice enclosure, placing it
within the open trough system. Dress and secure microcable as specified by local practice.
2. Adjust the microcable so any excess slack is accumulated at the Rapid Fiber Panel. This
slack is rewound on the cable spool after the cable is paid out to the termination point.
3. Determine if the microcables are terminated with MPO connectors (connectorized cables),
non-functional connectors (stub end cable), a fanout assembly (with pulling sock), or a
NG4access cabled module (with pulling sock). A special label (NON-FUNCTIONAL
CONNECTOR) is attached to microcables that are terminated with non-functional
connectors. The label is attached to the cable next to the connector boot.
4. If the microcable is terminated with an MPO connector, proceed to step 5. If the
microcable is terminated with a non-functional connector, proceed to step 6. If the
microcable is terminated with connector fanout assemblies, proceed to step 7. If the
microcable is terminated with an NG4access cabled module, proceed to step 8.
5. Complete the following for each cable terminated with an MPO connector:
a. Remove the pulling eye from each MPO connector by inserting and twisting a
screwdriver or coin as shown in
Note:
Due to space constraints in conduit, only cables with MPO connectors or MPO-like
non-functional connectors should be routed through conduit.
Note:
This procedure begins at the point where the RapidReel cable spool tray or external
spool is released and ready to be pulled as described in either
or
.
Caution:
Avoid using excessive force when unwinding microcable from the internal spool. If the
cable fails to unwind, check for obstacles or obstructions that would prevent the spool from
turning. The maximum recommended pull force that may be applied to the MPO connector
pulling eye, fanout assembly pulling sock, stub connector pulling eye, or to the cable itself is 40
lbs. (18.14 kg). Use the hand-wrap method if pulling on the cable by hand.
Note:
Microcables with stub end non-functional connectors look the same as microcables
with MPO connectors. Like MPO connectors, they are housed inside of black pulling
eyes; however, non-functional connectors are not optically terminated. They are crimped
to the cable jacket and strength member yarns. Non-functional connectors are cut off after
the cable has been fully unwound from the spool and is ready to be spliced.
