UNSPSC 43222828: Frequency division multiplexer

An electronic device or system that a device that selects one of several analog or digital input signals and forwards the selected input into a single line. The transmission medium is divided into channels divided into different frequency bands, and each information signal is converted into a transmission wave of the corresponding frequency band and transmitted.

UNSPSC 43222828 Frequency division multiplexer is a Commodity code that does not correspond to the work state and local governments are currently procuring under it. The recent opportunities tagged with this code reflect a wide range of telecommunications, communications infrastructure, and IT equipment services — satellite phone systems with push-to-talk capability, Motorola radios and accessories, VoIP telephone system replacements, fiber optic cable installation, legacy telephone system maintenance, emergency communications equipment, and cabling services — none of which are frequency division multiplexers or equipment that performs frequency division multiplexing. The code name appears to be a taxonomic mismatch to the actual procurement activity; the most recent opportunities show state and local buyers sourcing operational telecommunications services, legacy system maintenance, network infrastructure buildout, and emergency communications capabilities rather than the signal-processing or multiplexing hardware the code nominally describes.

The issuing bodies span state transportation departments, state IT procurement offices, county governments, school districts, and cooperative purchasing vehicles. The Texas Department of Information Resources (DIR), the State of Illinois Department of Innovation and Technology, Hillsborough County Public Schools, Collier County Board of County Commissioners, the City of Thomasville, Georgia, and Sourcewell (a Minnesota service cooperative) appear across recent solicitations. Recent opportunities are concentrated in Texas (DIR procuring indefinite-quantity wireless and satellite services, TxDOT procuring telecommunications equipment), Florida (Collier County sole-sourcing satellite communications, Hillsborough County Public Schools requesting telephone and security system maintenance twice), Georgia (Thomasville VoIP replacement), California (Long Beach fiber expansion re-bid), Illinois (legacy telephone maintenance emergency extension), and Washington state (Sourcewell law enforcement equipment cooperative). The Texas Department of Criminal Justice issued an RFO for telecommunication parts with a March 31, 2026 deadline, and the City of Long Beach rejected all bids for a fiber optic expansion project (R-7231) valued at approximately $20.6 million to $22.55 million after bid opening on April 2, 2026. The Texas Department of Information Resources is soliciting cabling services and related products through a cooperative contracts RFO (COOP2026SOL-00008) due June 12, 2026, at 2:00 PM CST, with an anticipated optional vendor conference on May 19, 2026.
