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

Channel Attenuation dB
Channel	Multimode		Singlemode
	850nm	1300nm	1310nm	1550nm
OF-300	2.55	1.95	1.80	1.80
OF-500	3.25	2.25	2.00	2.00

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 OM 3)

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).
