Autotest Overview
Autotest is a mature Kingfisher fiber optic test data transfer protocol in
use since 1994. It has been extended various times within its original
framework. Length testing is the latest extension on these instruments,
so may not be compatible with older Autotest instruments. There are
two basic modes of operation:
Two-Way Autotest
This is a common use for a pair of Two-Way testers, and for Tier 1
testing. On one fiber, it performs a bidirectional loss test in both
directions, with as many λ as the sources fitted to your instrument,
using either local or remote referencing. The instrument can display
the loss up to 3
λ . A single button push stores all results for a fiber into
memory. Or a single click of a connected computer with KITS™
software.
Instruments with the ORL feature will seamlessly add the ORL test
results from each end, at each
λ . This extra test requires no user
action, only a little extra test time.
Instruments with the cable length measuring feature seamlessly add
the cable length test result, with no user action.
A handy Autotest communications feature helps both users step
quickly through a large fiber array. This feature also links through to
real-time acquisition with
KITS™ software.
The instrument displays pass / fail / marginal.
One-Way Autotest
This mode is used with light sources and meters, and is less likely to
be used with a Two-Way tester unless just one instrument is in use.
This mode is near-equivalent to a basic light source and meter, but
with the λ synchronised. It can test one-way loss with as many λ as
the sources fitted to your instrument, using either local or remote
referencing.
The instrument can display the loss up to 3 λ . A single button push
stores all results for a fiber into memory. Or use a single click of a
connected computer with
KITS™ software. This software can also
merge two sets of one-way Autotest results into a single two-way
Autotest result.
Limiting Active Autotest Options
In some instances, better testing is achieved by restricting active λ to
only those required for the job at hand. This saves test time and
restricts pass/fail criteria.
For example, a 3
λ SM tester rotates by default around 1310, 1550,
1625 nm. If you just want to test at 1310 nm you can activate just 1310
nm only, which will then test 3x as fast.
