UNSPSC 83112303: Wave division multiplexing WDM

UNSPSC 83112303 Wave division multiplexing (WDM) is a Commodity code representing fiber-based metro ethernet transport services and related wide-area network (WAN) connectivity solutions that state and local governments procure to interconnect agency locations with broadband network points of presence. The Illinois Department of Information Technology is soliciting fiber-based point-to-point metro ethernet transport service to connect the Department of Transportation's Hardin Bridge location to an Illinois Century Network Point of Presence site, with 100 MB of bandwidth required and an estimated contract value of $45,000. State and local issuing bodies soliciting under this code include state departments of information technology, county transportation authorities, and regional broadband offices. The code spans a narrow range of recent activity: the Illinois procurement noted above (IFB 27448DOITTELECB53267, due July 30, 2026) is a firm-fixed-price, all-inclusive service procurement with fiber delivery mandated and no acceptable substitutes (copper, wireless, or satellite); San Mateo County Parks Department sought managed broadband connectivity services for remote field operations via RFP 2026RFP00539 (posted July 3, 2026, with local vendor preference ordinances applying); and the Colorado Broadband Office issued an RFI for LEO satellite compliance and performance monitoring across approximately 50,000 broadband serviceable locations, extending into a 10-year performance period. Geographic activity appears concentrated in Illinois, California, and Colorado, with secondary activity in Washington State (WaTech broadband ISP and wireline ethernet RFQs) and Texas (DIR cooperative cabling services solicitation). The recent opportunities mix terrestrial fiber metro ethernet (Illinois), multi-path broadband solutions including satellite and wireless (California parks), and emerging low-earth-orbit satellite monitoring (Colorado), indicating buyer appetite for flexible, scalable last-mile connectivity across diverse topography and infrastructure maturity.
