3.2.2.2
Power Attenuation Test
Power attenuation test shall be performed at each light wavelength of the
transmitter to be used on the circuit being tested. The flux shall be
measured at the FO receiver end and shall be compared to the flux injected
at the transmitter end. There shall be a jumper added at each end of the
circuit under test so that end connector loss shall be validated.
Rotational optimization of the connectors will not be permitted. If the
circuit loss exceeds the calculated circuit loss by more than 2 dB, the
circuit is unsatisfactory and shall be examined to determine the problem.
The Government shall be notified of the problem and what procedures the
Contractor proposes to eliminate the problem. The Contractor shall prepare
and submit a report documenting the results of the test.
3.2.2.3
Gain Margin Test
The Contractor shall test and verify that each circuit has a gain margin
which exceeds the circuit loss by at least the minimum gain margin
specified in paragraph FLUX BUDGET/GAIN MARGIN.
3.2.2.4
Analog Video Signal Test
Analog video circuits shall be tested using a signal conforming to EIA 170.
The monitor or automated test set shall be stable, and shall be as
described in EIA 170. If the result is unsatisfactory, the circuit shall
be examined to determine the problem. The Government shall be notified of
the problem and of the procedures the Contractor proposes to eliminate the
problem. The Contractor shall prepare and submit a report documenting the
results of the test.
3.2.2.5
Digital Video Signal Test
Digital video circuits shall be tested using a signal conforming to EIA 170.
The monitor or automated test set shall be stable, and shall be as
described in EIA 170. If the result is unsatisfactory, the circuit shall
be examined to determine the problem. The Government shall be notified of
the problem and of the procedures the Contractor proposes to eliminate the
problem. The Contractor shall prepare and submit a report documenting the
results of the test.
3.2.2.6
Performance Verification Test and Endurance Test
**************************************************************************
NOTE: This requirement pertains only to UMCS, IDS,
ESS and CCTV projects.
**************************************************************************
The FO data transmission system shall be tested as a part of the completed
[UMCS] [IDS] [ESS] [CCTV] [_____] during the Performance Verification Test
and Endurance Test as specified in Section [_____].
3.3
TRAINING
3.3.1
General
The Contractor shall conduct a training course for designated personnel in
the maintenance of the FO system. The training shall be oriented to the
specific system being installed under this specification. The Contractor
shall furnish training materials and supplies.
