**************************************************************************
A fiber optics (FO) data transmission system (DTS) shall be provided. The
data transmission system shall consist of fiber optic transmission media,
transmitter and receiver modules, modems, transceiver modules, repeaters,
cable and power line surge protection, terminal devices (such as
connectors, patch panels and breakout boxes) and power supplies for
operating active components. The data transmission system shall
interconnect system components as shown. Computing devices, as defined in
47 CFR 15, shall be certified to comply with the requirements for Class A
computing devices and labeled as set forth in 47 CFR 15.
1.3.2
Environmental Requirements
**************************************************************************
NOTE: Select equipment and cable temperature rating
within ambient temperature conditions at project
location. State additional requirements when
ambient conditions are more extreme than
manufacturers' equipment ratings (e.g., conformal
coating for 100% relative humidity or condensing
atmospheres, enclosure heaters or enclosure coolers.)
**************************************************************************
Equipment and cable to be utilized indoors shall be rated for continuous
operation under ambient environmental conditions of 0 to 50 degrees C 32 to
122 degrees F dry bulb and 10 to 95 percent relative humidity,
non-condensing. Equipment and cables to be used outdoors shall be rated
for continuous operation under ambient environmental conditions of [minus
40] [minus [_____]] to plus [75] [_____] degrees C [minus 40] [minus
[_____]] to plus [166] [_____] and humidity of up to 100 percent condensing
or as normally encountered for the installed location. All equipment and
cable shall be rated for continuous operation under the ambient
environmental temperature, pressure, humidity, and vibration conditions
specified or normally encountered for the installed location. Cables
installed in ducts, plenums, and other air-handling spaces shall be
installed per NFPA 70. Cables installed in plenums shall be plenum-rated
cables listed for the use. Cables installed in risers shall be riser-rated
cables listed for the use, unless the installed cable is identified as a
permitted substitution for the required riser-rated cable type.
1.3.3
Hazardous Environment
**************************************************************************
NOTE: Designer will show hazardous (classified)
environment area(s), type of hazard(s), and hazard
classification (Class I, II, or III, or
combinations; Divisions 1 or 2; Groups A, B, C, D,
E, F, or G or combinations; and operating
temperatures) on the drawings. Whenever possible,
avoid placement of the FO DTS equipment and cables
within the hazardous location to reduce installation
costs, and to simplify maintenance.
**************************************************************************
System components and wiring located in areas where fire or explosion
hazards may exist because of flammable gases or vapors, flammable liquids,
combustible dust, or ignitable fibers or flyings shall be rated for
Classes, Divisions, Groups and suitable for the operating temperatures and
