Wilcom has been manufacturing reliable, easy-to-use telephone line test equipment and transmission products since 1967. Our products include one-of-a-kind optical fiber testers and hard-to-find telecommunication test sets. Telephone, CATV, and LAN industries use Wilcom devices for much more than testing, maintaining and installing networks. We also offer a full range of transmission repeaters, line-powered amplifiers and loop extenders. Wilcom believes in long-term, mutually beneficial relationships. More than 95% of our revenue comes from repeat business. Our expanding base of international and domestic distributors and manufacturer's representatives extends to the Pacific Rim, Canada, Europe and Latin America.
