Fiber optic cable is the newer, faster way to transmit data. These send data signals using light (lasers) instead of electricity. Light signals can travel faster for higher bandwidth, suffer from less signal loss, and degrade less from electrical interference. Fiber optic cables come in a few different varieties with multiple types of cable as well as multiple connectors.

Types of cable include:

  • Single-mode
  • Multi-mode
    • OM1
    • OM2
    • OM3
    • OM4

Types of connectors include:

  • FC
  • LC
  • SC
  • ST
  • MTP/MPO
  • MTRJ

Fiber Cables

Single-mode

Single-mode fiber optic contains a very thin core, making it ideal for long-range transmissions. These cables can be incredibly long, with a single line potentially running for miles. The light transmitted by single-mode cable is between 1,300 and 1,550 μm, a frequency range that almost puts it into the infrared wavelength. This version of fiber optic cable is mainly used for telecommunications.

The name “single-mode” comes from the cable only transmitting a single mode of light
