About this file
This is a technical specification document for fiber optic cable associated with an Invitation to Bid (ITB# OFN/261008) issued by the City of Ocala, Florida through Ocala Utility Services/Resource Management for a Non-Stock Fiber Optic Cable Dearman Buildout project in Fiscal Year 2026. The specification details the AFL Flex-Span ADSS (All-Dielectric, Self-Supporting) Fiber Optic Cable (DNA-31683), a 24 single-mode fiber cable designed for aerial installation. The cable features 5 buffer tubes with color-coded fibers (12 blue and 12 orange fibers), an approximate outer diameter of 11.0 millimeters, and a cable weight of approximately 22 pounds per 1,000 feet. The specification includes comprehensive mechanical and optical performance data, including maximum rated cable loads of 587 pounds per foot breaking strength, dynamic bending radius of 17 inches, and maximum stringing tension limits. Installation requirements specify minimum bull wheel diameter of 77 inches, stringing sheave diameter of 46 inches, and maximum aerial stringing tension not to exceed 20 percent of the rated breaking strength. Sealed bids were required to be submitted electronically through the AURSI bidding system by 2:00 P.M. on August 10, 2026.
The specification document establishes rigorous standards for cable design, manufacturing compliance, and installation procedures in accordance with IEEE 1222, ITU-T G.652D/G.657.A1, and NESC/CSA standards, with RoHS compliance required. The cable is rated for environmental temperatures ranging from -50 to +70 degrees Celsius for storage, -40 to +70 degrees Celsius for operation, and -30 to +70 degrees Celsius for installation. Attenuation characteristics are specified at 0.35 dB/km at 1310 nanometers and 0.25 dB/km at 1550 nanometers. The document provides detailed reel capacity information for both wood and steel reels, ranging from 58 to 84 inches in flange diameter, with capacities up to 300-416 kilometers depending on reel type. Installation procedures and handling recommendations reference AFL's official installation instructions and video resources. Inquiries regarding the bid were directed to Mary Ann St. Laurent, Warehouse & Inventory Manager, at mstlaurent@ocalafl.org or (352-351-6705).

* - The stringing tension is always measured at the tensioner side. In general the maximum stringing tension should be a half of the maximum sagging tension and never should exceed 20% RBS of the ADSS Cable.
** - The value indicated is for the first and last structures of the pull and is based on 40 times the cable diameter with a minimum of 18 inches for any cable diameter. Smaller diameters can be used at tangent structures. Reference AFL's installation instructions for more details.
Reference AFL's "Recommended Installation Procedures for All-Dielectric, Self-Supporting (ADSS) Fiber Optic Cable" for detailed installation instructions.

Maximum lengths shown are the longest lengths that AFL offers. Longer lengths may be possible.
Ordered lengths should include a distribution of lengths, i.e., all reels cannot be ordered at the maximum. A typical reel length distribution is as follows:
6000m – 7000m ~ 15% of reels 4500m – 6000m ~ 55% of reels 2500m – 4500m ~ 25% of reels <2500m ~ 5% of reels
Wood reels with flex-wrap covering are standard. Non-returnable steel reels and/or wood lagging are available upon request. Additional reel sizes may be available upon request.
Minimum Arbor Hole Diameter:
Steel: 3-1/4in (8.2cm) Wood: 3-1/8in (7.9cm)
Steel reels are recommended for long term storage. Reference AFL's "Fiber Optic Cable Receiving, Handling and Storage" document for additional information.
Reel dimensions are typical and subject to availability at the time of shipment.
