NAICS 335921 - Fiber Optic Cable Manufacturing covers the production of optical fibers and the assembly of fiber optic cables used for high-speed data transmission and telecommunications. This industry focuses on the fabrication of glass or plastic fibers that transmit information via light pulses, providing the critical physical layer for secure, high-bandwidth networking. In the government contracting landscape, this sector is essential for establishing the backbone of secure communications, supporting everything from tactical field deployments and hardened facility installations to global diplomatic networking and aerospace data links. The competitive landscape features a mix of specialized manufacturers and diversified industrial suppliers. Key players such as PMI Industries, Inc., Pioneer Industries, LLC, and 3M Company operate within this space, ranging from niche small business providers to large-scale global primes. The presence of firms like Bahfed Corp and Reality Technology, Inc. indicates a market where both specialized cable fabrication and integrated technology solutions are required to meet rigorous federal specifications. The Department of Defense is the primary driver of demand in this sector, reflecting the massive requirement for secure, resilient communication infrastructure across military installations and operational theaters. Other significant buyers include the Department of Justice, Department of Commerce, and the Department of Homeland Security, which utilize these products for law enforcement and border security networks. Additionally, NASA leverages this NAICS code for high-performance data transmission in aerospace and research environments. The market is characterized by a high density of opportunities tied to national security and critical infrastructure modernization. Procurement patterns suggest a steady demand for specialized cabling that can withstand harsh environments or meet strict security certifications. For contractors, the opportunity lies in providing high-reliability components that integrate with broader systems integration projects, as agencies continue to upgrade legacy copper networks to high-capacity fiber optic architectures.

Small Business Size Standard

The SBA threshold that decides who can bid NAICS 335921 work as a small business.

1,000 employees
Applies to the whole industry code

The SBA cap for this NAICS (13 CFR 121.201). A business at or under it can self-certify as small for work in this code, which is what makes it eligible for a small-business set-aside. The cap is set per NAICS, so the same company can be small in one code and not in another.

13 CFR 121.201, effective January 1, 2026. The SBA revises the table roughly once a year.

Bidder counts reported on past federal awards in this NAICS (USAspending). An open opportunity has no bidders yet, so this is the historical norm for similar work, not a fact about this solicitation. Not all awards report bidder counts, and fewer bidders often means incumbent-held work rather than an easier win. Federal reporting of bidder counts fell from ~96% of awards (FY2016) to ~30% (FY2018 onward); the chart shows shares of reported awards, and washed-out stretches mark years with fewer than 30 of them.

High power hollow core fiber assembly for laser pulse compression
Solicitation # Req-369233
SLAC National Accelerator Laboratory, operated by Stanford University for the Department of Energy, is seeking a U.S. domestic source for a high power hollow core fiber assembly designed for second stage laser pulse compression. The required equipment includes a main fiber holder kit, stainless steel tubing, a vacuum window mount, a high power mounted fiber with a conical ceramic protection taper, an optical axis height adjustment kit, and a high pressure upgrade. The assembly must be compatible with a laser wavelength of 1030 nm, an input pulse energy of 1.75 mJ, and an average power of 70 W at a 40 kHz repetition rate, with a target output pulse duration below 10 fs. Technical specifications require the assembly to withstand a nominal maximum working pressure of at least 2.5 bar absolute and maintain a footprint with a short dimension of less than 0.2 meters. The award will be determined using the Lowest Price Technically Acceptable method, with a strong emphasis on the best lead time, as the complete assembly must ship within three months of the purchase order. Eligible offerors must be registered in the System for Award Management and provide documented evidence of feasibility regarding the target pulse duration. Payment terms are Net 30 days, and freight is FOB Destination Prepaid and Add for domestic suppliers. The procurement is governed by SLAC's Terms and Conditions for Fixed Price Commercial Supplies and Services and incorporates specific federal requirements, including the Buy American Act and various FAR clauses regarding computer software licenses and international transportation.
