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 ++ .
