UNSPSC 43223341: Combiner

A device that combines a multiple number of transmission signals to transmit in one transmission path without impedance change.

UNSPSC 43223341 Combiner (Commodity) represents fiber optic networking and telecommunications infrastructure components that state and local governments procure to expand broadband connectivity, support intelligent transportation systems, and establish redundant communication networks across distributed public facilities. Recent solicitations show state and local buyers purchasing combiners and related fiber infrastructure equipment as part of larger fiber deployment, dark fiber leasing, metro-Ethernet transport, and cabling installation projects.

State and local issuing bodies span diverse jurisdictions—city utilities (Palo Alto, Santa Monica, Ocala), county transit and toll authorities (Harris County Toll Road Authority, Broward County), school districts (Madison County Schools, Hillsborough County Schools, Clarke County Schools, Grenada School District), departments of transportation and information technology (Illinois DoIT, Georgia GDOT), and special-purpose authorities (Atlanta BeltLine, North Florida TPO). Illinois DoIT appears as a repeat buyer, procuring dark fiber IRU services and metro-Ethernet connectivity across multiple state agency locations. Recent opportunities cluster in infrastructure-led deployments funded through transportation surtax, broadband equity programs (BEAD), E-Rate, and federal infrastructure grants. The City of Brownsville, Texas issued a 5G infrastructure IFB (due July 30, 2026) for RF design validation, fiber network integration across eighty-two locations, and intelligent transportation system connectivity. Hillsborough County Public Schools and other school districts solicit structured cabling, fiber optic installation, and maintenance services through RFPs and ITBs. Burke County, Georgia procured 4.8 million feet of fiber optic cable in multiple strand configurations under BEAD federal requirements. Illinois DoIT issued multiple RFQs for fiber-based metro-Ethernet last-mile connectivity and sole-source dark fiber IRU contracts to Stratus Networks, i3 Broadband, and Bluebird Network, totaling over $1.6 million across recent awards.

Activity concentrates in Texas, Florida, Georgia, Illinois, Connecticut, Pennsylvania, North Carolina, and California, with secondary activity across Mississippi, Oregon, and other states. Representative recent opportunities include the City of Palo Alto RFQ for 75,000 feet of 432-fiber optic cable (due July 1, 2026), Collier County's security and generator project at Immokalee Airport including fiber duct bank installation (due July 31, 2026), Madison County Schools' 281-drop structured cabling RFP for low-voltage data infrastructure (due July 20, 2026), and the City of Charlotte's on-call cabling services RFP spanning fiber optic, data, and access control installations (due May 18, 2026). Illinois DoIT's DOT-R506 Fithian metro-ethernet procurement (due May 12, 2026) and the state's multiple dark fiber sole-source awards to incumbent carriers highlight state-level demand for fiber backbone services supporting point-of-presence connectivity and redundant network paths. Broward County's Pine Island Road adaptive traffic control and fiber optics systems bid (due March 9, 2026, with 30 percent CBE goal) and multiple fiber construction projects signal sustained municipal investment in ITS fiber integration. The code shows active procurement momentum through mid-2026 with strong geographic diversity across Midwest, South, and coastal markets; fiber and dark fiber services dominate the opportunity mix, followed by structured cabling installation and metro-ethernet transport services.
