Fiber broadband technology
FCC Form 477 technology code 50: 2,618,693 census-block deployment records nationwide. Filing volume and state reach are separate measurements.
Filing volume rank is not state-reach rank
Fiber ranks #7 of 10 FCC technology codes by census-block records, and #2 of 10 by number of states with at least one filing (55 states).

Top states for Fiber by reported deployment records
FCC Form 477 fixed broadband deployment data (June 2020 status)
Texas leads Fiber filings with 195,111 records ; California is second at 138,663. Counts are provider-by-census-block filings for technology code 50, not subscriber totals.
About Fiber
Fiber (Optical Carrier / Fiber to the End User) delivers internet via fiber-optic cables run to homes or businesses. It offers the fastest speeds available, commonly 1–10 Gbps, with symmetric upload and download speeds.
Fiber state-reach reading
Fiber opens on state reach: #2 of 10 codes by states with ≥1 filing (55 states), with 2,618,693 records behind that footprint. FCC technology code 50 is a fiber-optic family label in Form 477.
Fiber sits in the middle third of Form 477 technology codes by record volume (2,618,693–3,788,469). Mid-pack codes often mix real competition pockets with sparse rural filings under the same technology label.
The lead state (Texas) holds 7.5% of Fiber filings (195,111 records). That is a moderate peak: several states still move the national total. Form 477 historically let providers mark a whole census block from a single reachable address; treat these counts as declared capability, not address-level availability, speed, or price.
