In-Line Attenuators
The In-Line attenuators provide a fixed level of attenuation and feature excellent return loss. Low cost and performance determine them for universal using in optical networks.
- Return loss > 50 dB
- Insertion loss on customer´s demands
- Fiber or cable version
- Pigtail with connector by specification
