DESCRIPTION: Optelecom designs and manufactures fiber-optic products for government and industrial customers, including lasers for use in military night-vision systems.

DEVELOPMENTS: The company reported a 26 percent rise in earnings for the fiscal year ended Dec. 31, reducing its losses from $112,000 in 1983 to $82,000 in 1984. The improvement came in the fourth quarter, with $204,000 in profits compared with a loss of $91,000 during the same quarter of 1983. Optelecom attributes the growth to new contracts, including a $1.3 million contract with the U.S. Air Force for 30 laser illuminators. 97: CORDATUM INC. 4720 Montgomery La. Bethesda, Md. 20814

DESCRIPTION: Tech Serv manufactures miniature aerial target systems for use in military training and radio control equipment for target guidance systems.

DEVELOPMENTS: A lapse in a major contract with the U.S. Army during the fiscal year ended June 30, 1984, accounted for Tech Serv's losses for that period. The five-year contract with the Army for manufactured aerial targets was not renewed until fiscal 1985.

For the first half ended Dec. 31, Tech Serv reported profits of $60,000, compared with a loss of $67,000 during the same period a year earlier. 99: HITECH ENGINEERING CO. 8260 Greensboro Dr. McLean, Va. 22102

DESCRIPTION: Hitech Engineering provides security products and consulting services to corporations and government agencies concerned that their communications are being intercepted. The company has developed a Tempest/Trace operating facility for improving the security of electronic devices and computers.

DEVELOPMENTS: This year was Hitech's first as a public company. Its initial stock offering last June brought in $3 million (6 million common shares at 50 cents each), and the influx of funds allowed the company to begin several projects. The start-up costs, however, resulted in a net loss for Hitech's first year of operation.

Hitech said one of its primary objectives last year was to establish itself as a fully certified provider of Tempest technology. The company also reported that it obtained two small contracts from Mitsui Engineering & Shipbuilding Co. for nuclear and safeguard projects. 100: NETWORD INC. 6801 Kenilworth Ave., Riverdale, Md. 20737

DESCRIPTION: Netword provides hard copy electronic-mail services to business and industry.

DEVELOPMENTS: Netword, which has 86 clients, is tied into the U.S. Postal Service E-COM System. A major development last June was the Postal Serice announcement that it would attempt to sell the E-COM System, in which about $50 million already has been invested. The sale of E-COM might force Netword to seek other companies that provide similar electronic-mail delivery services. So far, the Postal System has not yet found a buyer.
