Thunder is the newest generation high-volume audio/data/intercom transport link from Grass Valley. Thunder transports up to 80 audio, intercom or data paths, configurable in 8-path groups (10 groups total), all on one or two strands of fiber, at the lowest price and most compact size ever available. Simply equip the compact 1 RU frame with the appropriate Thunder Bolt I/O cards to create a fiber optic link that can solve virtually any audio/intercom/data connectivity situation in the teleproduction environment, buying only the components you need.
