Infonet Services Corp., which supplies communication services to large companies over its high-speed data network, filed for a $1-billion initial stock sale to raise money to develop its network infrastructure. The El Segundo-based company filed with the Securities and Exchange Commission to sell Class B shares, which will have less voting power than its Class A shares.

Infonet, which began operations in 1969, counts some of the world’s largest telecommunications companies, including KDD Corp., KPN Telecom, Swisscom and Telefonica International Holding, as its top shareholders. Infonet had $303 million in revenue in the year ended March 31. Underwriters include Merrill Lynch & Co. and Warburg Dillon Read.
