In
KITS™, observe the “Secure Mode” symbol which is must
be active for Tier 1 testing data security
✓
Check computer date & time
If intending to work into instrument memory:
✓
Set up a suitable Tag ID
✓
Set up the overall job size etc
✓
Empty the instrument memory
✓
Check instrument date & time
If intending to use USB download, check that the instrument can
recognise your USB key(s) and that they have enough free space.
You are now ready to start testing the project on-site.
✓
First, you may want to continuity test the cabling prior to loss
testing, since you want to minimise any (e.g. rectification)
disturbances to the cabling once it’s properly tested. Use the
instrument tone function, or VFL if fitted, or go a bit further
and use Autotest to also check performance and length.
✓
You will want to check polarity, e.g. ensure fiber pairs are
not reversed. This may or may not be part of continuity
testing, depending on the site conditions etc. Also check the
cabling labelling one by one. Use the instrument tone
function, or VFL if fitted, or go a bit further and use Autotest
to also check performance and length
Once you have verified that the site & cabling continuity is looking
promising, polarity is good, and labelling is good, (all key parts of Tier
1 testing) it’s time to perform and
record the formal loss (maybe ORL)
and length test, with the expectation that there will be little re-work or
cabling disturbance during or after this phase.
The following should have been covered prior:
Personnel training & accreditation, equipment suitability & calibration,
test method, test
λ
, fiber & connector type, test lead selection &
verification, site labelling, instrument & reporting software general
operation, cleaning & inspection equipment & processes, referencing,
pass/fail parameters.
Two-Way Loss, Length & ORL Testing Procedure
•
If not done already, verify the patch leads
•
Reference both instruments using 1, 2, 3 cord methods as
relevant
T
o work live into KITS™ software:
•
Connect the computer, start-up
KITS™
with instrument on
& connected to USB (so the program sets up to match the
instrument). This can be at either instrument.
•
Once connection is established, go to the Live Data Tab
•
Fill in job details as needed (green cells)
•
KITS ribbon / Pass Fail Setup, select test standard or other
•
Enter / adjust any relevant data
