UNSPSC 43221802: Optical network or communication filters

A component that enables increasing or targeting the optical signal as it travels between destinations. Optical devices use to transmit a select range of light frequency, or to separate ranges of light frequencies in optical communication circuits

UNSPSC 43221802 Optical network or communication filters — a Commodity code — encompasses specialized filters and optical transmission components state and local governments procure to support network infrastructure upgrades, traffic management systems, and enterprise data communications. Recent solicitations show state and local agencies buying optical transceivers, single-mode fiber optic cable with termination services, network switching equipment with optical interconnect capabilities, and fiber optic signal communication systems integrated into adaptive traffic control networks and campus-wide switching platforms. The code surfaces primarily in school district E-Rate-funded network modernization efforts and in municipal traffic management and public safety infrastructure projects. Issuing bodies include county school districts (Houston County, Bibb County, Fayette County, Sarasota County in Georgia; Pinellas County in Florida; Grosse Pointe in Michigan; Hays CISD in Texas), municipal governments (City of Eugene, City of Atlanta Department of Aviation, City of Palo Alto, Broward County), county public works departments (Seminole County in Florida), county IT departments (Wake County in North Carolina; Jackson County in Georgia; Dalton Utilities in Georgia), and statewide cooperative purchasing vehicles (Region 7 Purchasing Cooperative in Texas). Network infrastructure replacements dominate the recent activity; optical components appear as integral parts of larger switching and routing modernizations rather than as standalone line items.

Geographic activity concentrates in the Southeast (Georgia, Florida), with secondary clusters in the Southwest (Texas), Midwest (Michigan), and Pacific Northwest (Oregon, Washington). Recent representative opportunities include Seminole County Public Works' ITB for network equipment including switches and optics to support Advanced Traffic Management System upgrades (July 22, 2026 response date); Jackson County Board of Commissioners Georgia RFP for Cisco network switching and routing equipment with professional services and optics (July 2, 2026, mandatory pre-proposal conference June 18); City of Palo Alto RFQ 194354 for approximately 105 edge switches, 4 core switches, and 212 fiber transceivers to replace aging traffic signal communication equipment (May 20, 2026); and Houston County School District ITB #26-028 for HPE Aruba network switches and transceivers under E-Rate funding (February 20, 2026). School districts pursuing E-Rate-funded Category 2 infrastructure replacements drive consistent demand; most optical filters and transceivers are bundled with core switch and access point procurements rather than solicited independently, reflecting the integrated nature of modern network modernization projects.
