NEW YORK (Bloomberg) — Bermuda-based Global Crossing Ltd., the network operator that survived one of the largest US corporate bankruptcies, said demand for computer networks is rising world-wide, fuelling orders and revenue.

Sales have climbed sequentially for six straight quarters and orders reached a "record level" over the past six or seven months, chief executive officer John Legere said yesterday at an investor conference in Phoenix. The spread of Internet-protocol systems, which help stitch together international networks, is spurring demand. More stable prices and industry consolidation also contributed to the company's $4.4 million in orders last month, Legere said.

Global Crossing rose 4.9 percent to close on $20.82 in Nasdaq Stock Market trading yesterday. The shares fell 10 percent last year.

The company's network transmits video feeds for CNBC Europe and connects defense contractor Northrop Grumman Corp.'s customers worldwide in simultaneous flight simulations.
