What is SPF?

Small form-factor pluggable (SFP) also called Mini-GBIC.

Small form-factor pluggable transceiver

How to recognize fiber cable?

  • by diameter?
    Multi mode: 50/125μm ~ 62.5/125μm
    Single mode: 9/125μm

  • by color?
    Single-mode: cable color is usually yellow, and connector is blue

  • different range
    Usually, applications are ~2km for multi-mode, ~30km for single-mode.

  • 1000Base-SX is : multi-mode fiber cable caonnector

  • 1000Base-LX is : single-mode fibre

Fiber optic connector types?

FC connector is smaller compared to the SC. SC has two voids (void = vođica) and two hooks to connect in connector. FC has one.

  • Duplex-connectors are just two simplex connectors together. Can be FC or SC.

SC

SC is a snap-in connector also with a 2.5 mm ferrule that is widely used for it’s excellent performance. It was the connector standardized in TIA-568-A, but was not widely used at first because it was twice as expensive as a ST. Now it’s only a bit more expensive and much more common It’s a snap-in connector that latches with a simple push-pull motion. It is also available in a duplex configuration.
