Description

This project is intended to replace the Dense-Wave-Division Multiplexing (DWDM) equipment that provides optical broadband network backbone communications between County FiberNet hub sites. The equipment has reached the end of its useful life and is nearing end of support. In FY24, TEBS will conduct an analysis to evaluate the replacement options for this equipment. In FY25, TEBS will order and begin installing the new equipment at all 20 FiberNet hub sites.

Justification

The County's 10-year-old DWDM network needs to be replaced due to the sale of Garage 2 to United Therapeutics and the FiberNet hub relocation. The County has a 20 site DWDM network. The existing DWDM network was manufactured more than 10 years ago. This DWDM equipment is no longer manufactured or supported by manufacturers, and is not compatible with new DWDM systems. The DWDM network supports public safety sites, the 911 center traffic, WSSC Water, and Montgomery College among other sites and applications. United Therapeutics will contribute the cost of replacing the equipment currently located in Garage 2.
