For customers considering introduction of optical connector end face inspection equipment

Contamination on the end face of optical connectors accounts for a large proportion of the causes of defects in optical networks.
Contamination on optical connector endfaces that cannot be seen with the naked eye causes increased reflection and loss.

Advantages of observing the optical connector end face before connecting the optical connector

Observing the end face before connecting can prevent failures due to contamination on the end face.
Scratches and stains on the end face can be visually identified, enabling the identification of the location of loss occurrence and shortening of network downtime.

We recommend the following cycle to maintain a healthy network.
