About Us





TesCom has been serving the Telecommunications and CATV Industry for over 35 years. TesCom was founded in 1982. We continue to follow three simple business principles that formed the basis for the company:

  1. We provide the services our customers need.
  2. We perform these services with the highest quality standard.
  3. We give the customer exceptional value.

Today our company is divided into three divisions:

Manufacturing and Sales Divisions: We manufacture Halcyon, CopperPro, 635 Quickbert, and NetDSL test equipment, Tiempo 6400 series timing and synchronization clocks, and semiconductor thermocouples. Everything we sell is guaranteed and certified by our internal Laboratories so our customers are assured of high quality products and full warranty coverage after the sale.
