The Company is involved in manufacturing and performs consulting services in the fiber optic and telecommunications in domestic and international markets. The Company purchased OPTIM Incorporated surgical illumination business in 1999 thus enhancing its market share in the medical fiber optics industry.
The Company has been a pioneer in wireless communication having invented the first wireless local area network back in 1984. The computer networking device was marketed under the name TCL-100 and became quite popular with major customers like Pitney Bowes until Motorola and NEC got into the same business with miniaturized products. However, the TCL series products established the Company as a technology leader in this field enabling the Company to get consulting contracts for system integration.
