DWDM Upgrade

CURRENT STATE, SCOPE OF WORK, AND SPECIAL CONSIDERATIONS

B.1 CURRENT STATE:

Thornton is a home-rule city in Adams County, Colorado, located ten (10) miles northeast of

Denver.

On or about 2019, the Thornton Information Technology Division (“Thornton IT”) implemented

Thornton’s current CWDM network backbone technology. Thornton IT is now in the process of

migrating from its existing CWDM environment to a higher-capacity DWDM architecture capable

of supporting increased bandwidth demands, improved wavelength management, and long-term

scalability across the organization’s network backbone. Thornton began this upgrade in 2025

and will continue this Project through 2028 or 2029.

The requested DWDM upgrade equipment includes passive DWDM multiplexing and add/drop

modules, LightGuide Cross-Connect (LGX) chassis components, tunable 10Gb DWDM optical

transceivers, and related mounting and media conversion hardware. The solution is intended to

maximize utilization of existing fiber assets while enabling future network growth and improved

operational flexibility.

To ensure compatibility with Thornton’s existing DWDM equipment, Bidders must bid the

Approved Networks (a brand of Legrand) brand-name equipment requested by Thornton.

Substitute equipment will not be acceptable.

B.2 ESTIMATED QUANTITIES:

Thornton made its first purchase of DWDM equipment in 2025. Thornton’s anticipates making

annual purchases of DWDM equipment through 2028 or 2029, when the Project will be

completed. The anticipated quantities for 2026 are provided below, as well as the remaining

quantities for 2027 through 2028/2029, and the total quantities of DWDM equipment for this

Project:
