Fiber cables summary for interview
Fiber cables summary for interview
– we have 3 layers for the optical fiber cables :
Core : made from silicon dioxide and it Carry the signal
cladding : confines light to Core
buffer / coating : protect the Core and cladding from moisture and physical damage
……
– 2 main types of optical fiber cables :
Tight buffered : contain multiple Fibers , used in indoor applications
Loose tube : contain multiple Fibers and used with outdoor applications
…….
– single mode vs multi mode
single mode : the Core diameter is 8-10 Mm
used with long distance , high capacity
main types of fiber standards in SM :
- G652
- G653
- G655
……
multi mode : core diameter around 50-62 Mm
used with Short medium distance and capacity due to modal dispersion
main types for MM fibers
- OM1
- OM2
- OM3
- OM4
- OM5
……
Types of fiber cables according to different applications :
- distribution
- breakout
- submarine
- ribbon
- armored
- cordage
…….
types of connectors :
- LC
- ST
- SC
- MTRJ
- FC
- MPO
…..
types of SFP :
- SFP
- SFP+
- XFP
- CFP
- CXP
…..
– Fiber windows :
- 850 nm
- 1310 nm
- 1550 nm
