Calient raises $5M for fiber optic management

Calient Networks, which provides switching equipment to manage fiber optic networks, has raised $5 million in a third round of venture funding (pdf announcement here). TeleSoft Partners, which first invested in the San Jose, Calif. company back in 1999, led the round, according to VentureWire.

Calient makes switches that use small mirrors to redirect optical signals, which it says provide a reliable, automated, low-cost system for service providers, government agencies, and optical network equipment providers. The company says the need for its services is growing with the increased traffic for social networking sites and online video. It has raised more than $250 million in funding.
