3.2. FIBER OPTIC CABLE REQUIREMENTS
A. Cable Configurations: Cable shall be 48-strand singlemode, fiber optic cable. All
Cable provided under this contract shall be from the same manufacturer utilizing
identical specifications and configured as follows:
1. Fiber Optic Cable shall be designed for use in underground outside plant
environment. Cable shall be fabricated by a certified ISO 9001
manufacturer and meet or exceed the following requirements and
Standards:
a ) The diameter of the fiber optic cable is not to exceed 12mm. The
physical weight of the cable shall not exceed 133 kg/km.
b ) Dielectric construction using center strength member configuration.
c ) Dry tape water blocked for interstitial space between buffer tubes
and cable jacket.
d ) Cable shall support optical fiber strands separated into four (4),
water block gel filled buffer tubes. Each buffer tube shall be color-
coded following the TIA 598 standard (Blue, Orange, Green and
Brown), Each buffer tube shall contain twelve (12) color coded fiber
strands compliant with Telcordia GR0020 and the requirements of
EIA/TIA-598-A Standard.
e ) The cable shall have footage markings every two feet on the outer
cable jacket and be marked “City of Fort Collins Traffic” every five
feet.
f ) The fiber optic cable shall be design to withstand a pulling tension
of 2700 N without changing characteristics of the optical fibers. The
minimum yield strength of the cable shall be 19.30 MPa (2800 psi)
for unaged cable and 14.50 MPa (2100 psi) for aged cable.
g ) The cable shall be designed to function between -40°C to +70°C
throughout the life expectancy of the cable.
B. Fiber Strand Requirements: The cable shall include 48 strands of singlemode optic
fiber suitable for support of Course Wavelength Division Multiplexing (CWDM)
transmission meeting or exceeding the following specifications:
1. Fiber must comply with EIA/TIA 455 and IEC 793 test methods for required
attributes.
