Analysts attending the NXTcomm trade show in Chicago this week came away with a positive outlook on the industry.

“The general tone [of the show] was positive, and our meetings detailed renewed growth in the sector,” RBC Capital Markets analyst Mark Sue wrote in a research note.

The investment community turned up “in force” at the event, according to Morgan Keegan analyst Simon Leopold, highlighting investor interest in telecom.

“We didn't identify a single technology theme, yet were reminded that an industry recovery remains underway,” Leopold wrote.
