EIA-232 Connections—Extend connections up to 110 kilometers using the SEL-2829, SEL-2830, and SEL-2831 Fiber-Optic Transceivers and ST-terminated fiber-optic cables.

Fiber Ethernet—Implement single-mode fiber-optic Ethernet connections using LC-terminated optical cables.

Field Termination—Purchase unterminated cable and build cables easily on the job site with the Termination Tool Kit.


  • Choose the cable types and lengths to match your applications:
    • Standard-duty simplex cable for indoor applications (one fiber)
    • Standard-duty zipcord for indoor applications (two fibers)
    • Heavy-duty duplex waterproof cable for indoor and outdoor applications (two fibers)
  • Built using Corning 9/125 μm optical fiber with ST, SC, or LC connectors.
  • Connect SEL fiber-optic transceivers and compatible fiber-optic ports on relays and controllers for safer serial communications with high data integrity.
  • Complete fiber-optic Ethernet systems by connecting Ethernet ports of switches, routers, multiplexers, relays, and more for high-speed, safe, and reliable network communications.

The Firmware IDs for older versions of the firmware can typically be found in Appendix A of the instruction manual.
