Columbia County hereby requests sealed bids for the installation of fiber optic cable. Bid Bond 5% of bid amount For interpretation or correction of any of the bid material, a request may be made to David Drews, MIS Director, at david.drews@columbiacountywi.gov. Any questions should be received no later than Thursday, September 11, 2025, at 2:00 p.m. (CST). Questions received after that time will not be considered. Questions and answers will be posted by 4:30 p.m. (CST) on Friday, September 12, 2025. o The manufacturer(s) of cabling and connectivity components shall be a company specializing in and having a minimum of five years of documented experience in producing products similar to those specified in this and related sections. o The contractor shall have been in this line of business for a minimum of five (5) years and have completed one (1) or more projects of scope 50% or more of the magnitude specified by these documents. o Contractor shall have necessary certifications to provide for Guarantees as specified herein. o Contractor shall be an active participant in Installers Program operated by Manufacturer of Cabling or Termination Components used. Contractor shall be a participant in this program at time of Bidding and remain so throughout project. o Contractor shall have on the project team at a minimum one (1) certified Installer trained by the manufacturer(s) of the cabling, hardware and accessories installed under this project. o At least one (1) member of each test team shall be factory trained/certified in use of the test equipment. The project foreman shall have been factory trained in the use of the test equipment. o Test Data - Fiber Optic Media o Test results shall include a record of test wavelengths, cable type, cable and fiber I.D., measurement direction, test equipment type, model and serial number, calibration date, test date, reference setup, and crew member name(s). o Use United States customary units (e.g., "feet") rather than International System units (SI; metric) unless otherwise instructed. o Submit Attenuation (Insertion Loss) Test Results for each fiber in electronic form as follows: In the native format of the test instrument. Summarized to include a list of all fibers and the corresponding attenuation values. The Summary shall be in Adobe Acrobat (.pdf) format and include all records. Attenuation values documents should be actual measured Loss and not "Headroom" relative to the Pass/Fail limit. o Submit OTDR in electronic form in the native format of the test instrument. o Provide final testing results in electronic pdf format to the MIS Department. o Cable Jacket: o Material: Polyethylene (PE). PE shall be compounded to provide protection against the effects of ultraviolet light and limit the growth of fungus. o Cable jacket shall be free of holes, splits, and blisters. o The cable jacket shall be marked with the manufacturer's name, words identifying the cable type (e.g., "Optical Cable" or "Fiber Optic Cable"), year of manufacture, and sequential length markings in feet. The marking shall be in a contrasting color to the cable jacket. Max. Tensile Load o >= 12-fibers During Installation: 1332 Newton's (300 lb. force) (no irreversible change in attenuation) Long Term:600 N (135 lb. force) o < 12-fibers During Installation: 1000 Newton's (225 lb. force) (no irreversible change in attenuation) Long Term:300 N (67 lb. force) o Bending Radius: o During Installation: 20 times cable diameter o No Load: 10 times cable diameter o This cable shall be suitable for installation in building riser systems, in conduit, in cable tray or in innerduct. o Cable shall be a Tight Buffer design. o Cable materials shall be all dielectric (no conductive material). o Exception: Where armored cable is specified, that cable element may be metallic. o Cable jacket color shall indicate fiber type per TIA-598. o OM4 (50/125 LASER-optimized Multimode) AQUA o OS2 (Single-mode) YELLOW o The cable jacket shall be marked with the manufacturer's name, date of manufacture, fiber type, flame rating, UL symbol, and sequential length markings every two feet. o Splice Enclosure shall be used at indoor locations where a sealed assembly is not required, where used to house splices associated with splicing of factory-prepared cable assemblies ("pigtails") and/or where identified on project drawings. o Enclosure shall be rack mounted. o Enclosure shall provide storage and protection of fiber splices. o Enclosure shall allow cables and jumpers entry from left and right sides. o Rack-mounted enclosures at a termination location shall incorporate top and bottom removable access panels at the rear of unit for vertical pigtail entry from the Enclosure to Connector Panel enclosure. Integrated splice and connector housings are acceptable for small fiber counts. o The Optical Connector shall be LC-type. o The connector ferrule shall be ceramic or glass-in-ceramic. The optical fiber within the connector ferrule shall be secured with an adhesive to prevent pistoning and other movement of the fiber strand. o The attenuation per mated pair shall not exceed the following values: o Multimode 0.75 dB o Single-mode 0.75 dB o All terminated fibers shall be mated to Duplex LC Adapters. Adapters shall be mounted on a panel that, in turn, snaps into the enclosure. The proposed enclosure shall be designed to accommodate a changing variety of connector types. o Fiber Optic Patch Panels shall be rack mounted. o Unit height shall be 1 RU minimum. o The patch panel enclosure shall provide for strain relief of incoming cables and shall incorporate radius control mechanisms to limit bending of the fiber to the manufacturer's recommended minimums or 1.2", whichever is larger. o Access to the inside of the patch panel enclosure during installation shall be from the front and/or rear. Panels that require any disassembly of the cabinet to gain entry will not be accepted. o All Fiber Optic Patch Panels shall provide protection to both the "facilities" and "user" side of the coupling. The patch panel enclosure shall be configured to require front access only when patching. The incoming cables (e.g., Backbone, Riser, etc.) shall not be accessible from the patching area of the panel. The enclosure shall provide a physical barrier to access of such cables
