Appendix: Installing Duplex Multimode Fiber Cable
Appendix. Installing Duplex Multimode Fiber Optic Cable
1. We recommend that you use OM3 multimode fiber optic cable (50/125 and
62.5/125) terminated with SC duplex connectors to interconnect the local unit
and remote unit. Table A-1 shows the specifications.
Table A-1. Duplex multimode fiber optic cable specifications.

2. You may need to order appropriate cable lengths that conform to the application
environment; however, the maximum cable length should not exceed 5120 feet
(1600 meters), approx. 1 mi.; otherwise, signal degradation may occur (especially
for video resolution).
3. Do not exceed the cable bend radius. Fiber optic cable can break when kinked or
bent too tightly, especially during pulling.
4. Do not twist the cable. Twisting the cable can stress the fibers. Tension on the
cable and pulling ropes can cause twisting.
5. Don’t look into the ends of any fiber optic cables. You might be exposed to
invisible laser radiation.
6. Follow the cable manufacturer's recommendations. Fiber optic cable is often
custom-designed for the installation, and the manufacturer may have specific
instructions for how to install it.
