Appendix D
Fiber Cable and LC Connector
This appendix provides specifications for the fiber cable and LC connector used
with the 1756-EN2F EtherNet/IP fiber module or the 1783-ETAP1F and
1783-ETAP2F EtherNet/IP fiber taps.
Figure 5 - Fiber Cable
Specifications
The 1756-EN2F EtherNet/IP fiber module and the 1783-ETAP1F and
1783-ETAP2F EtherNet/IP fiber taps use a fiber cable and LC connector. The
fiber cable is typically used in 1 m (3 ft), 2 m, (6 ft), 3 m (9 ft), 5 m (15 ft), and
100 m (300 ft) lengths, but supports lengths up to 2 km (1.24 mi).
The fiber cable and LC connector supports these specifications.
IMPORTANT
You can special order a fiber cable in any length up to 2 km (1.24 mi) from
your fiber cable vendor.
