The total attenuation budget for each fiber cable length (end-to-end) shall equal the allowed
attenuation for the fiber (0.2 dB per km times the length in km) plus the attenuation for each
splice and connector. For example, a cable length of 3 km with 1 splice and 2 connectors
would have an attenuation budget of (3 km x 0.2 dB/km) + (2 x 0.2 dB) = 1.2 dB.
Test all installed fiber optic strands after splicing and termination that have a length greater than
500 feet with an OTDR (Optical Time-Domain Reflectometer) per TIA/EIA-455-61:
End-to-end bi-directional signature trace with fault finding, connection point reflection, fiber
bend, pressure point location, etc.
One wavelength, 1300 nm for multimode strands.
One wavelength, 1550 nm for singlemode strands.
Multimode fiber connector losses ≤ 0.5 dB at 850 nm
Singlemode fiber connector losses ≤ 0.2 dB at 1310 nm
Multimode fiber splice losses ≤ 0.3 dB at 850 nm
Singlemode fiber splice losses ≤ 0.2 dB at 1310 nm
Localized attenuation shall not exceed 0.5 dB at any point
Fibers that are broken or damaged shall be replaced at no cost to the owner and replaced fiber
optic cables shall be re-tested.
System Tests.
The following procedures shall be performed by the Consultant:
Audio fidelity Verification: Driving the system with pink noise and measuring the response from 40 Hz
to 16k Hz. Digital Signal Processing will be used to adjust the response of the system (s) to fit the
requirements of the space.
Video Signal Verification: From all source inputs (for cameras, character generators, video tape units,
etc.) through all VDAs, A/D and D/A converters, processors, switchers, etc., to all signal destinations.
Verification of correct signal timing for each source via each path will be made using standard test
patterns. Each processing device will be checked; the signal will pass through the device in the no
processing mode such that unity luminance, chrominance, and signal timing and phasing conditions
are achieved.
