Fiber Optic Cabling: SC & ST Connectors Explained

Click For Summary
SUMMARY

The discussion clarifies the differences between SC and ST fiber optic connectors. The ST connector is round and utilizes a push-and-twist mechanism, resembling a BNC connector, while the SC connector is rectangular and designed for a slide-in slot connection. Additionally, it highlights the two primary categories of fiber cables: single-mode fibers, which have a core diameter of approximately 9 microns and transmit infrared laser light at wavelengths of 1,300 to 1,550 nanometers, and multi-mode fibers, with a core diameter of about 62.5 microns, transmitting infrared light from LEDs at wavelengths of 850 to 1,300 nanometers.

PREREQUISITES
  • Understanding of fiber optic connector types, specifically SC and ST connectors.
  • Knowledge of single-mode and multi-mode fiber optic cables.
  • Familiarity with fiber optic transmission wavelengths.
  • Basic comprehension of optical networking concepts.
NEXT STEPS
  • Research the specifications and applications of SC and ST connectors in networking.
  • Learn about the differences in performance between single-mode and multi-mode fibers.
  • Explore the impact of fiber optic cable core diameter on signal transmission.
  • Investigate the latest advancements in fiber optic technology and connector designs.
USEFUL FOR

This discussion is beneficial for network engineers, telecommunications professionals, and anyone involved in the installation or maintenance of fiber optic systems.

Does anybody know what the SC and ST connectors stand for [?]

thanks joe

The ST and SC fiber cables are the difference in the connectors on the end.
-ST connector is round and looks like a BNC connector (push and twist).
This page has a pic of an ST connector: http://www.datapro.net/products/1441.html
-SC connector is rectangular (slide in slot).
This page has a pic of an SC connector: http://www.datapro.net/products/1443.html
(There are links on those pages with other types of connectors as well.)

More info you didn't ask for...
Two main catagories of fiber cables:
->Single-mode fibers have small cores (about 3.5 x 10-4 inches or 9 microns in diameter) and transmit infrared laser light (wavelength = 1,300 to 1,550 nanometers).

->Multi-mode fibers have larger cores (about 2.5 x 10-3 inches or 62.5 microns in diameter) and transmit infrared light (wavelength = 850 to 1,300 nm) from light-emitting diodes (LEDs).
