Port Diagram of Optical Interface
The Neutrik opticalCON DUO cable has two fiber channels, named channel A and channel B. Since Lightware
fiber extenders use only one fiber for signal transmission, the other fiber can be used by other optical devices.
The unused fiber channel is accessible by the break-out connector.
