Fiber Optic Cable Routing Special care should be taken when mounting and routing fiber optic
cable to prevent damage that could degrade signal transmission.
– You must maintain a minimum bend radius of 1 inch at all times.
If you cannot maintain this bend radius due to cabinet constraints,
remove the plastic strain relief as shown in Figure 4.4 to allow
you to maintain the bend radius at 1”.
If the strain relief is removed, connect the cable with the blue
connector to the dark gray connection on the board. Connect the
cable with the black connector to the light gray connection on the
board. The cable with the blue connector is the receive (RX)
cable, and the cable with the black connector is the transmit (TX)
cable.
– If the strain relief is removed from the cable assembly, the cable
weight may need to be be supported to prevent the connectors
from unplugging in some applications. If your application has a
long cable droop, or an unsupported wire bundle, use a zip tie to
support the excess weight.
– If a cable is kinked or nicked during installation, it MUST be
replaced. A kinked or damaged cable greatly reduces signal
strength and could cause the drive to fault.

To remove the strain relief/latching cover squeeze the two latches
inward and lift the upper half off from the cable end (bottom) of the
cover assembly.
