  • This type of MM firbe (at the highest OFL bandwidth) has been available from Brand-Rex for 4 years.It (mentioned earlier in Ken’s slides) it can allow more power budget for 300m or shorter 10G links It can allow links up to 550m but only if the 10G power budget is metAnd it may be used for the new (40G/100G) higher speed networks if IEEE or FC (fibre channel) approve
  • Last of the optical fibres to discussOM4 is nearly hereThe specification IEC 60793-10-A1a.3 has to be finalised by IEC SC86A WG1 and the national committees which ie expected in Q1/Q2 2010.The area causing difficulty is the over filled launch – the current test method is being reviewed and may result in a new method based on prediction from DMD( differential mode delay ( used for the effective laser launch bandwidth.
