Cabling Pinouts (Fiber Optic)

  • For Transmitting Data over Fiber Optic Cable, we use Hot-Pluggable Transceivers.

  • An Optical transmitter shines a LED/Laser light in the core which is made up of Fiberglass & is covered with cladding.

  • Both Cladding+Core it roughly the size of the diameter of a Human Hair.

  • Cladding is further covered with a buffer then a strengthener & finally an Outer Jacket to prevent delicate Fiber Glass from breaking.

  • There are 2 types of Fiber Modes:

  • Single Mode Fiber (Yellow)

  • Multi-Mode Fiber (Blue/Red)

Single Mode Fiber (Single angle of Light) (Yellow):

  • Provides High Bandwidth at High Speeds over Long distances

  • Core's Diameter is 9µm (Micrometer)

  • Uses Laser

  • The Maximum distance Coverage is 550 Meters.

Multi-Mode Fiber (Multiple angles of Light) (Blue/Red):

  • Provides High Bandwidth at High Speeds over Medium distances

  • Core's Diameter is 50µm (Micrometer)

  • Uses LED

  • Maximum distance Coverage is 550M, 10km, 40km ++ .
