E3X-DA-AT-S
Fiber amplifier
Digital fiber amplifier with active threshold
control for dust and dirt compensation
The active threshold E3X-DA-AT-S digital fiber amplifier compensates for light power
reduction caused by dirt and ensures stable operation.
• Active threshold control for high stability
• Alarm output for maintenance warning
• Area detection function for quality inspection or sensing range control
