The Dense-Wave-Division Multiplexing (DWDM) project supports the replacement of aging equipment that form the backbone of the County's FiberNet optical broadband network. The existing DWDM infrastructure has reached the end of its useful life and is nearing end-of-support from the manufacturer, increasing the risk of service disruptions and limiting the ability to scale or maintain the network.

In FY25, TEBS initiated procurement and began phased replacement of DWDM equipment across all 20 FiberNet hub sites. Installation and integration activities will continue through FY26.

The DWDM network is critical to County operations, supporting public safety communications, 911 center traffic, WSSC Water, Montgomery College, and other essential services. The urgency of this replacement has increased due to the sale of Garage 2 to United Therapeutics, which necessitates the relocation of a key FiberNet hub. United Therapeutics will contribute funding to cover the cost of replacing DWDM equipment currently located at Garage 2.
