** INTRODUCTION***************
	There are two 1300nm data files on the IEEE site.
This one OM2_MC50_3X_tau1300_1_5Kb.zip has a 5000 mode delay set constructed
to match the OM2 overfilled BW distribution using the OM1 delay set. The reason 
to use this data set is as a check against any biases entering the data set in
the process of "augmenting" the set below.

The other OM2_MC50_3X_tau1300_6_5Kb.zip has a DIFFERENT 5000 mode delay set 
constructed by augmenting the transformed OM1 data set by a factor of 6x to 
30,000 sets before selecting 5000 actual fibers and determing the best match
to the OFL BWs.

CONTENTS of *.zip file  OM2_MC50_3X_tau1300_1_5Kb.zip
1. READ_ME_FIRST_STEP2_OM2_1300.txt
	This file (contents & explanation)
See the References above for an introduction.

2. OM2_MC50_3X_tau1300_1_5Kb.dat
	5000 mode delays at 1300nm for installed base OM2 modeling (50um 500/500)
	creating using set of 5,000 test fibers shifted from OM1 mode delay set.
	This data set has the mode delays.  

	It needs to be used with the
	mode power distribution for the lasers/launch conditions being modeled.

	We are assuming that only the first 10 groups be given significant power, and 
	that the outer two are considered attenuated. 

	These mode delays approximate a manufacturing distribution, just as was done
	for the TIA simulations of OM3 fiber (850nm 10GbE 300m) described in 
	JLT Vol. 21 May 2003 pp.1256-1275, and pp.1242-55.  
	
	THE DISTRIBUTION INCLUDES FIBERS WHICH DO NOT MEET THE 500/500 SPEC and needs
	to be truncated using the data in file (3.) just below.

3. OM2_Step2_OFLBW_summary.dat

Set of OFL1300 and 16um offset BWs corresponding to installed base OM2 model
	This data set is used to truncate the modeling results so that only fibers
	meeting the OFL 500/500 requirement are included.

4. PXG_50um_1300_26_12.dat
	Set mode power distributions for gaussian beams launched into 1% Delta 50um
	core radius fibers at 1um intervals from 0um to 25um.  26_12 refers to 26 
	radial positions and 12 mode groups supplied.

5. OM2_MC50_1_BW_16umP.dat
	1300nm OFL BW and 16um offset BW for comparison & reference purposes.
6. OM2_MC50_1_BW_10umP.dat
	1300nm OFL BW and 10um offset BW for comparison & reference purposes.

7. Abbott_OM2_revision_11_2005.pdf
	Presentation on this data set (in REFERENCE list at top of this file).
	Includes scatter plots of OFL850 vs OFL1300 and the cumulative probability
	distributions.
