The U.S. Department of Commerce, National Oceanic and Atmospheric Administration (NOAA), Acquisition and Grants Office (AGO), Satellite and Information Acquisition Division (SIAD), issues this Request for Quotation (RFQ) No. 1332KP26Q0051 for the procurement of replacement fiber transmitter modules for the Fairbanks Command and Data Acquisition Station (FCDAS) in Fairbanks, Alaska.

This acquisition is conducted under FAR Part 12 (Acquisition of Commercial Products and Commercial Services), utilizing simplified acquisition procedures in accordance with active Revolutionary FAR Overhaul (RFO) class deviations.

SET-ASIDE STATUS:

This requirement is a 100% Total Small Business Set-Aside. The North American Industry Classification System (NAICS) code is 334220 (Radio and Television Broadcasting and Wireless Communications Equipment Manufacturing) with a Small Business Size Standard of 1,250 employees.

BRAND NAME ONLY RESTRICTION:

In accordance with FAR 13.106-1(b)(1), this requirement is restricted to Brand Name Only for Ortel components. The contractor shall deliver two (2) new brand-name Ortel SITU3013 Fiber Transmitter Modules. The FCDAS baseline architecture is engineered exclusively around proprietary Ortel fiber optic links to deliver X-Band capabilities to the station's 13M antennas. These modules must operate at a nominal 1550 nm wavelength and match existing optical output profiles to integrate seamlessly with downstream telemetry processors without retrofitting or modifications. Alternative brands are non-conforming and will not be accepted.
