1 The minimum Effective Modal Bandwidth is ensured by means of Differential Mode Delay (DMD). This fibre should be used with transmitters according to TIA/EIA-492 AAAC IEC 793-2-10.
2 A tighter inner mask (from 0 to 18µm) is used as defined in TIA/EIA-492 AAAC or IEC 793-2-10, type A1a (from 5 to 18µm).
