UNSPSC 83112301: Dark fiber

UNSPSC 83112301 Dark fiber is a Commodity code capturing state and local procurement of dark optical fiber infrastructure — specifically lease, installation, maintenance, and connectivity services for point-to-point and multi-site fiber optic networks. State and local governments use this code to acquire bare fiber capacity (unlit optical fiber pairs) to support wide-area network connectivity, emergency communications systems, utility operations, and inter-agency telecommunications without paying for lit carrier services. Recent solicitations show procurement officers buying dark fiber lease and maintenance renewals, point-to-point metro ethernet transport over fiber infrastructure, and full-lifecycle fiber installation with associated testing and monitoring.

Recent activity spans state departments, counties, municipalities, and special-purpose districts across California, Illinois, Florida, and Washington. The California Department of Technology has posted multiple dark fiber solicitations — a June 2026 IFB for single-mode optical fiber installation, lease, and maintenance connecting state campus locations with a September delivery deadline, and an August 2026 RFQ for dark optic fiber lease and maintenance services renewal. The Illinois Department of Innovation and Technology issued an IFB in July 2026 for redundant metro ethernet transport over fiber connecting state correctional facilities to Illinois Century Network points of presence, with October 2026 bid opening. A representative opportunity: the California Department of Technology's SC 25-0212436 Dark Fiber IFB (posted June 23, 2026, bids due July 7, 2026) solicited single-mode optical fiber installation, lease, maintenance, and monitoring from the State Compensation Insurance Fund Campus in Vacaville to the Gold Camp Campus in Rancho Cordova, with a three-year base term and two optional one-year extensions, small business and DVBE preferences, and September 30, 2026 completion deadline. Geographic spread includes California and Illinois as primary recent sources, with secondary activity in Washington and Florida. The code shows steady procurement activity among state technology offices and utility operators focused on infrastructure renewal and inter-facility connectivity.
