A summary of all of the testing results of the Clear Fiber bundles since the start.

Criteria for passing (somewhat arbitrary, but based on results from the 3 bundles used in Run 17 that were deemed "good"):

• Average transmission of above -65%
• No single fiber in a bundle has transmission below -75%

Bundles to use in Run 18:

FB#	Status	Comments	Average	Max	Full Sheet
1	Healthy	First bundle; repolished twice	-63%	-68%	FB01
2	Healthy	Results from 2nd test; avg unchanged from first test	-55%	-62%	FB02
3	Healthy		-54%	-67%	FB03
4	Healthy		-63%	-73%	FB04
5	Healthy		-62%	-71%	FB05
6	Healthy	Repolished once	-62%	-68%	FB06
7	Healthy		-61%	-73%	FB07
8	Healthy	Repolished 3 times	-63%	-72%	FB08
9	Healthy		-64%	-71%	FB09
10	Healthy		-62%	-68%	FB10
11	Healthy		-62%	-73%	FB11
13	Healthy	Repolished 3 times	-64.8%	-73%	FB13
14	Healthy		-62%	-73%	FB14
15	Healthy		-62%	-73%	FB15
16	Healthy		-62%	-73%	FB16
17	Healthy		-63%	-70%	FB17
18	Healthy		-61%	-69%	FB18

21	Healthy		-64%	-72%	FB21
23	Healthy	Repolished once	-63%	-72%	FB23
24	Healthy		-63%	-74.6%	FB24
26	Healthy		-62%	-66%	FB26
27	Healthy		-57%	-68%	FB27

Failing Bundles that can still be used in Run 18 in an emergency:

FB#	Status	Comments	Average	Max	Full Sheet
22	Injured	Failing upon retest. Not sure what's going on	-61%	-77%	FB22
12	Injured	Single fiber glows on both ends, possibly cracked	N/A	N/A	N/A
28	Injured	Failing final test. Also even/odd difference of 6%	-61%	-78%	FB28

Bundle Under Construction: FB25 (Broken splitter; construction not completed, but can be fixed and polished for the future if needed)




In summary, at the moment we have:

• 24 Passing Bundles (FB1-FB11, FB13-FB21, FB23-FB24, FB26-FB27)
• 3 Failing Bundles (FB28 has a fiber at -78%; FB12 has a fiber glowing on either end, so it was set aside. Has never been fully tested, but the glowing fiber was actually passing testing; FB22 failing upon retest; 2 fibers below -75%)  
• 1 Incomplete bundle (FB25 had a tube splitter that broke. It can be fixed, polished and used, but of course should only be used as a last resort)
