Crown Castle Fiber LLC

Crown Castle Fiber LLC, doing business as Crown Castle Communication, is a for-profit limited liability company and subsidiary of Crown Castle International that provides dark fiber connectivity, Ethernet circuits, dedicated internet access, and broadband telecommunications services to federal agencies as a prime contractor (95% of recent awards) across full-and-open, non-set-aside procurements. Headquartered in Houston, Texas, the company operates in the wired telecommunications carriers space (NAICS 517111 and related) and competes without SBA designations.

Crown Castle Fiber LLC's federal footprint centers on dark fiber and point-to-point Ethernet service delivery. Representative work includes a $372 thousand delivery order from the National Institute of Standards and Technology under the GSA Multiple Award Schedule for dark fiber services (awarded December 2021, completion November 2026), a $367 thousand delivery order from the National Library of Medicine, also under MAS, for dark fiber support (awarded March 2023, completion February 2026), a $157 thousand purchase order from the Defense Counterintelligence and Security Agency for 10GB Ethernet telecommunications service in Hanover, Maryland (awarded December 2021, completion March 2027), and recurring DEA purchase orders for internet and Ethernet services totaling tens of thousands of dollars annually across Buffalo, Phoenix, and other locations. A $3.6 thousand Coast Guard purchase order in June 2026 for dark fiber service between the Academy and an external child development center in New London, Connecticut, and a $171 thousand Air Force Materiel Command purchase order for repair, maintenance, and emergency response on a two-strand dark fiber connection between Hanscom Air Force Base and MITRE Corporation (awarded September 2025, completion August 2030) round out recent prime activity.

Customer concentration is diffuse but anchored by defense and civilian IT infrastructure agencies. The top five funding agencies by award count account for 55% of recent awards: the Defense Information Systems Agency (19 awards, $766 thousand combined potential value), the Department of Justice Drug Enforcement Administration (10 awards, $182 thousand), the National Institute of Standards and Technology (5 awards, $1.1 million), the Department of the Navy Fleet Cyber Command (5 awards, $347 thousand), and the Consumer Product Safety Commission (3 awards, $255 thousand). When ranked by combined potential value, the GSA Federal Acquisition Service and Smithsonian Institution Office of the CIO dominate the dollar view — GSA carries a single award valued at $9.3 million and the Smithsonian a single award valued at $2.1 million — reflecting MAS contract ceiling values rather than task order frequency. DISA and NIST remain significant dollar customers even in the value ranking.

Crown Castle Fiber LLC places task orders under the GSA Multiple Award Schedule (7 task orders, $1.3 million combined potential value) and has a long-standing presence on DISA and other defense agency purchase order vehicles. The company operates across thirty distinct customer agencies, indicating broad federal agency exposure but relatively small average award magnitude.

Activity has been flat to declining. The vendor received five awards in 2022, seven in 2023, seven in 2024, six in 2025, and three awards through mid-2026. Seventeen awards with ultimate completion dates in the next twenty-four months carry $1.5 million in combined potential value, representing moderate recompete exposure concentrated in DEA, DISA, NIST, and other standing customer relationships.

Crown Castle Fiber LLC maintains a small subcontract footprint. The vendor subcontracts to Fluor Marine Propulsion LLC on Naval Nuclear Laboratory management and operations (sub-award modification in January 2025 adding $368 thousand) and to The Aerospace Corporation on point-to-point fiber connections to AWS Secret Domain between El Segundo and Columbus, Ohio (awarded June 2022). The company also acts as a sub-recipient on National Science Foundation grants: a Florida International University research award (IRNC: Core Improvement-Atlantic Wave SDX project) in which Crown Castle provides 100G dark fiber links and monitoring support between colocation facilities in South Florida (sub-award dated April 2026), with prior FIU sub-grant funding of $67 thousand in 2024 for the same project scope.

Recent five-year data shows 77 total awards spanning prime and sub work. The company's primary NAICS classification is wired telecommunications carriers (39 awards), and PSC coding reflects telecommunications and network transmission services (31 awards under IT and Telecom—Telecommunications and Transmission). Crown Castle Fiber LLC's awards are predominantly small to mid-sized purchase orders and delivery orders, with combined potential value of $18.2 million across the portfolio and $8.4 million in obligated dollars as of the source date. The company's parent, Crown Castle International, holds nationwide telecommunications infrastructure assets including fiber and tower networks that enable the subsidiary's federal service delivery.
