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
