Comparison of '568-B Series Versus '11801:2002 2nd Edition Fiber Cabling Performance Specifications

Optical Fiber Cabling and Component Specifications:

'568-B Series
Horizontal Link Insertion Loss ≤ 2.0 dB at 850nm or 1300nm
Horizontal Link With CP Insertion Loss ≤ 2.75dB @ 850nm or 1300nm
Centralized Link Insertion Loss ≤ 3.3 dB @ 850nm or 1300nm based on three connector pairs
Centralized Plus Open Office CP Link Insertion Loss ≤ 4.1 dB @ 850 or 1300nm based on three connector pairs
Backbone Link Insertion Loss = Cable Atten + Connector Insertion Loss + Splice Insertion Loss
Connector Insertion Loss ≤ 0.75 dB
Splice Insertion Loss ≤ 0.3 dB
Cable Atten ≤ 3.5 dB/km at 850nm for 62.5/125µm and 50/125µm
Cable Atten ≤ 1.5 dB/km at 1300nm for 62.5/125µm and 50/125µm
Cable Atten ≤ 0.5 dB/km for singlemode outside plant cable
Cable Atten ≤ 1.0 dB/km for singlemode inside plant cable
'11801:2002 2nd Edition
Connector Atten ≤ 0.75 dB
Splice Atten ≤ 0.3 dB
Cable Atten ≤ 3.5 dB/km at 850nm for 62.5/125µm and 50/125µm
Cable Atten ≤ 1.5 dB/km at 1300nm for 62.5/125µm and 50/125µm
Cable Atten ≤ 1.0 dB/km for singlemode (no differentiation between inside and outside plant cables)

Multimode Optical Fiber Modal Bandwidth (Overfilled Launch):

'568-B Series
Bandwidth ≥ 160 MHz-km at 850nm for 62.5/125µm
Bandwidth ≥ 500 MHz-km at 850nm for 50/125µm
Bandwidth ≥ 500 MHz-km at 1300nm for 62.5/125µm and 50/125µm
Note:
Additional performance specifications for 50/125µm cables are provided in ANSI/TIA/EIA-568-B.3-1. These requirements are harmonized with fiber type 'OM3' as specified in ISO/IEC 11801:2002 2nd Edition.
'11801:2002 2nd Edition
Bandwidth ≥ 200 MHz-km at 850nm for 62.5/125µm and 50/125µm (OM1)
Bandwidth ≥ 500 MHz-km @ 850nm for 62.5/125µm and 50/125µm (OM2)
Bandwidth ≥ 1500 MHz-km @ 850nm for 62.5/125µm and 50/125µm (OM3)
Bandwidth ≥ 500 MHz-km at 1300nm for 62.5/125µm and 50/125µm (OM1, OM2 and OM3)
Note:
Fiber type OM3 specified in ISO/IEC 11801:2002 2nd Edition, requires laser launch bandwidth of 2000 MHz-km at 850nm. This requirement is assured by testing differential modal delay (DMD).
