Here's a brief overview of the ceramic ferrules used in these
connectors:
1. FC Ceramic Ferrule:
* Typically made of zirconia (zirconium oxide)
* Ferrule outer diameter: 2.5 mm
* Fiber bore diameter: 125 μm (for single-mode fibers)
* Threaded design for connection
* Commonly used in telecommunications and premises cabling
2. SC Ceramic Ferrule:
* Often made of zirconia or alumina
* Ferrule outer diameter: 2.5 mm
* Fiber bore diameter: 125 μm (for single-mode fibers)
* Push-pull design for connection
* Widely used in local area networks (LANs) and data centers
3. LC Ceramic Ferrule:
* Typically made of zirconia
* Ferrule outer diameter: 1.25 mm (smaller than FC and SC)
* Fiber bore diameter: 125 μm (for single-mode fibers)
* Compact push-pull design
* Commonly used in high-density applications, such as data centers
and premises cabling
4. ST Ceramic Ferrule:
* Often made of zirconia or alumina
* Ferrule outer diameter: 2.5 mm
* Fiber bore diameter: 125 μm (for single-mode fibers)
* Bayonet-style twist-lock design
* Used in older fiber optic systems, but largely replaced by newer
connector types
