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:
