UNSPSC 43222823: Wave division mulitplexer WDM

WDM (wavelength division multiplexing), in which several baseband-modulated channels are transmitted along a single fiber but with each channel located at a different wavelength. Each of N different wavelength lasers is operating at the slower Gbps speeds, but the aggregate system is transmitting at N times the individual laser speed, providing a significant capacity enhancement. The WDM channels are separated in wavelength to avoid cross-talk when they are (de)multiplexed by a non-ideal optical fiber.

UNSPSC 43222823 Wave division multiplexer WDM is a Commodity code that nominally covers optical networking hardware, but recent state and local solicitations show minimal activity directly aligned with the code's scope. The recent opportunities tagged under this code instead reflect broader networking equipment procurement — primarily Cisco switching and routing hardware, Apple-branded computing devices, and wireless telecommunications services. State and local governments buying under this code category are obtaining network infrastructure components, authorized-partner distribution channels, and related support entitlements, with mandatory vendor qualification requirements (such as Cisco Partnership certification or manufacturer authorization) driving the selection process. Issuing bodies include county sheriffs' offices, state information-resource departments, county IT departments, and cooperative purchasing vehicles serving multi-jurisdictional consortia. When properly scoped, procurement under this code typically requires new, factory-sealed equipment sourced exclusively through authorized channels, with pricing that includes shipping, freight, support entitlements, and administrative fees but excludes installation, configuration, and professional services unless explicitly requested.

Recent opportunities show activity concentrated in the Southeast and Texas. Chatham County Sheriff's Office (Georgia) issued ITB 26-0114-6 on September 17, 2026, seeking two Cisco Catalyst 9500 network switches and related OEM hardware with bids due October 20, 2026, with a 30 percent combined M/WBE participation goal. Wake County's IT Department (North Carolina) issued RFQ 26074 on June 26, 2026, for Cisco networking equipment at the Sommerset 2 site with bids due July 10, 2026. The Texas Department of Information Resources posted RFO DIR-CPO-TMP-561 on July 28, 2026, for Apple-branded products and related services (a broader technology portfolio) with responses due November 19, 2021. Texas DIR also issued RFO DIR-CPO-TXA-610 on May 26, 2026, for cellular, wireless, pager, and satellite services with responses due July 23, 2026 — a services-heavy solicitation outside the equipment focus typical of this code. Sourcewell, a Minnesota cooperative purchasing vehicle, posted RFP 061626 on May 12, 2026, for law enforcement equipment on behalf of participating counties in Washington and nationwide jurisdictions, with proposals due June 16, 2026. The code shows limited genuine wave-division multiplexer activity; most recent procurement centers on authorized Cisco hardware distribution and broader IT commodity purchases rather than optical-layer networking components.
