In 2006, Test-Um (known for Lil' Buttie compact buttsets, and cable testers), was acquired by JDSU, a leading provider of communications test and measurement solutions and optical products for telecommunications service providers, cable operators, and network equipment manufacturers.
The Test-Um brand will be gradually phased out, and products will get the JDSU label. New products will use JDSU's purple and gray colors, replacing the Test-Um blue and yellow. During the transition period, you may get a product that differs in color and brand label from the photos on this website.
