Tier 1 Test Example
We give here an example of a typical Tier 1 Test / Acceptance /
Certification test. Prior to this, the organization needs to determine the
required test standard, test method, and ensure trained & accredited
staff are available.
We assume a two-way Autotest (bi-directional) test method. This is
faster and easier than a one-way Autotest test method, adds length
(and ORL if available) testing, and is the “highest” loss test method
available, accepted by all standards. Just hook-up one fiber up at a
time, once only.
It is noticeable that a good part of this testing is up to personnel and
associated procedures. The equipment plays a role in supporting
“Tier
1 Testing ” but is not in itself adequate to ensure compliance.
Don’t do this test until you are confident that the relevant physical
cabling/ labelling and related site aspects are “stable”.
Post-test physical site access needs consideration. The system may
get “accepted” but then later, someone unplugs and re-plugs a
connection, then it may fail due to dirt etc. This is when the blame
game starts
☺
Prepare equipment:
✓
Ensure your tester has required λ , fiber & test types
✓
Check equipment calibration status
✓
Check that instrument has correct connector types
✓
Check inspection & cleaning materials & qty available
✓ Check you have materials needed to secure or identify post-
test access to site, closets, racks, ducts, connections etc.
✓
Check spare batteries & micro USB power lead.
✓
Determine project labelling sequence to be used
✓ Determine number of fibers to be tested
✓ Verify exact test method(s)
✓
Check and verify operation with the required referencing
method(s) (1, 2 ,3 fiber etc)
✓
If helpful, restrict the instrument test λ .
✓ Check, label & document test leads, test through adaptors
& verify their performance. Maybe have separate low-grade
leads to be used for continuity & polarity checking.
✓
Ensure equipment familiarity, including communications
methods
✓ Set up test pass/fail parameters in the instrument
If intending to work (live or later) into KITS™ software:
✓ If intending to use KITS™ software, ensure it’s installed,
connects, and verify that it’s doing want you want
✓ Select test standard & enter relevant details, or enter new
test standard if needed
✓
In KITS™ , set up and save the project details for later use
