The Expanded Beam Performance technology is an advanced fiber optic solution. It offers high-end transmission characteristics over many mating cycles. The excellent optical performance remains unchanged even under mechanical stress, environmental influences and harsh ambient conditions.
Since there is no direct contact between the contact ends, Expanded Beam connections are relatively insensitive to contamination and can be cleaned easily. Under normal conditions, cleaning every 5000 mating cycles is sufficient. This ensures reliable transmission without damage.
