4. Let adhesive dry for 45 seconds. Rotate the lever arm counterclockwise and release ribbonized fiber from
ribbonizer.
Note:
Inspect fiber order with magnifying glass.
5.
Measure 5.13 in (130mm) from the jacket mark to end of the fibers and trim the ribbonized fiber end
evenly.
Measure to ensure 1.19 in (30mm) of ribbonized fiber still remains at the end as shown.
Note:
Trim only after the adhesive has dried.
Maintaining Polarity Method B for Fiber Splicing of QWIK MPO Connectors
Please note that for repair and restoration, it is important to understand the polarity configuration of
CommScope’s
cable assemblies.
Important: CommScope trunks follow method B fiber polarity.
1. For
Commscope
cable assemblies with the connector keys facing up, channel 1 on End A of the cable
assembly always goes to channel 12 on End B of cable assembly.
Likewise channel 12 on End A goes to channel 1 on End B of cable assembly.
2. This represents method B polarity per TIA 568C3 standards.
3. When repairing end A of a female trunk cable assembly, the blue fiber should always be positioned as
channel 1 (top/ far side in the splicer).
When repairing end B, the blue fiber should always be positioned as channel 12 (bottom/ near side of the
splicer). See Table 1, next page.
Ferrules on female trunks should be inserted into the housings (keys up) with the ferrule window facing
down. See Table 2, page 10.
Note:
Fiber Ribbon Splicing with Method B Polarity Appendix on the last page shows an example of the Method
B polarity MPO connector splice.
