UNSPSC 43221810: Optical multiplexer

A type of device that converts and transmits the electric signal, such as multiplexing and demultiplexing for return signal of optical communication, detection of synchronizing signal, generation of synchronization clock, photoelectric transformation and others into optical transmission signal.

UNSPSC 43221810 Optical multiplexer is a Commodity code with minimal recent state and local procurement activity directly aligned to the code's nominal scope. The opportunities posted under this code over the past four months span satellite communications services, law enforcement radio equipment, IT hardware procurement, legacy telephone system maintenance, VoIP telephone system replacement, fiber optic infrastructure, and transportation signal control equipment—a range that diverges significantly from optical multiplexing equipment and suggests either misclassification in state agency tagging systems or extremely limited demand for discrete optical multiplexer units among state and local buyers. The one opportunity with the closest connection to optical or telecommunications infrastructure is the Texas Department of Information Resources (DIR) cooperative procurement for cellular, wireless, pager, and satellite voice and data services (TEX-AN-WPS, due July 23, 2026), which encompasses infrastructure services but does not isolate optical multiplexer equipment as a line item.

State and local issuing bodies posting under this code include county governments (Collier County, Florida and Santa Clara County, California), independent school districts (Hillsborough County Public Schools and Fairfax County Public Schools), state departments (Texas DIR, Texas Department of Criminal Justice, State of Illinois, and Texas Department of Transportation), cities (Long Beach and Thomasville), and cooperative purchasing vehicles (Sourcewell). Geographic activity spans Florida, California, Virginia, Texas, Illinois, and Washington, with no concentration suggesting sustained demand in any single state or region. The most recent opportunities with substantial scope are the TEX-AN-WPS cooperative satellite and wireless services contract (Texas DIR, response due July 23, 2026), Fairfax County's IT hardware and services procurement (RFP, due July 13, 2026), and Hillsborough County Public Schools' infrastructure communications failure systems maintenance (ITB, response deadlines in February and April 2026). The absence of recent solicitations explicitly requesting optical multiplexers, optical transmission equipment, or wavelength-division multiplexing systems suggests that this code may see limited activity in state and local procurement or that jurisdictions are tagging such procurements under different commodity codes.
