Glossary useful for selecting Fibre Unit

Key terms for selection

The following is the key terms for selecting a fibre unit and their meaning.

Fibre unit length

The length of a fibre unit. A longer fibre unit can be installed at a location farther from the fibreoptic amplifier.

Ambient temperature

The range of temperature in which the fibre unit can be used. To use a fibre unit at high ambient temperature, it is recommended to select a heat-resistant type.

Bend radius

The index indicating the maximum radius in which the fibre unit can be bent and still operate without problems. Fibre units with smaller bend radius are beneficial in locations where routing is difficult.

Detecting distance

The distance from which the sensor can detect targets.

Optical axis diameter

This index is mainly used for thrubeam model fibre units. For thrubeam fibre units, this is the size of object that will obstruct the optical axis entirely.

Minimum detectable object

The size of the smallest target which the fibre unit can detect.
