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).
