Introduction
This application note provides information and guidance on how to best route the fibers and position the splice protectors in the DFE100. The DFE100 has a capacity of 24 fusion splices and two mechanical splices. Typically the DFE100 is used to repair a drop fiber in FTTH applications and only one or two fibers require splicing within the enclosure to re-connect the damaged cable.
Fiber Winding
If only one or two fibers are to be spliced as is the most common situation,
the technician should utilize splice locations 1 and or 12 so that the chance
of a Macrobend is minimized. Using position #1 or #12 can sometimes be a
challenge due to the fibers “memory” and if the fiber was cut short due to a
bad cleave etc.
It is suggested that two or more loops of fiber are utilized so as to enable
any future rework.
The following fiber winding convention should be used to minimize the possibility of Macro bends.
Splice 1 – 6 Fiber 1 Splice holder RHS & Fiber 2 Splice holder LHS
Splice 7 – 12 Fiber 1 Splice holder LHS & Fiber 2 Splice holder RHS
Mech. Splice 1 Fiber 1 Splice holder RHS & Fiber 2 Splice holder LHS
Mech. Splice 2 Fiber 1 Splice holder LHS & Fiber 2 Splice holder RHS
RHS = Right Hand Side
LHS = Left Hand Side
Note that the direction of fiber winding for both fibers is reversed at Splices 6 and 7.
If this method is used, the minimum bend radius of standard Singlemode fiber will not be violated.
For example as shown in the drawings below:
Fiber #1 Splice holder LHS & Fiber #2 Splice holder RHS; to position the
fusion splice in Splice #12. Is interpreted as:
Fiber #1 is routed counterclockwise and goes to the LHS of Splice #12 and
Fiber #2 is routed clockwise which goes to the RHS of Splice #12.
The picture below shows the DFE100 with two fibers loaded into the splice tray as would be typical with a FTTH drop fiber repair. The orange fiber on the left-hand side routed counterclockwise and the orange fiber on the right-hand side routes clockwise so that the splice protector mounts in splice #11 position.
The four fiber retention wings are positioned to keep the fibers captive to the base of the DFE100 so the fibers do not fall or spring out of position.
The picture below shows the DFE100 with 12 fibers loaded into the splice tray. Note how the fibers are compliant with their minimum bend radius requirements as the instructions in this application note were adhered to.
