These universal adapter caps fit all current models of OWL optical power
meters. The U2.5-4 connects to 2.5mm connectors such
as ST, SC, and FC, and the U1.25-4 connects to LC, MU, and other 1.25mm
OWL optical power meters take advantage of a flexible universal
connector port system which allows multiple fiber optic connector styles to connect to the same port. Fiber optic connector ferrules
come in two common sizes: 2.5mm (for ST, SC, FC, etc.) or
1.25mm (LC, MU, and other SFF connectors). A universal adapter cap is
available for each ferrule size.
What gives our universal port its flexibility is that only the
ferrule is inserted into the port. Since there is no latching
speak of, most connectors can connect to this port as long as the
ferrule size matches the adapter cap.
Each cap is designed so that once the ferrule is completely
inserted, the cone of light from a fiber connector falls completely
the photo detector, regardless of how the connector may turn, twist, or
wiggle in the port. Because of this, you can be assured that
the optical power reading will always be accurate.
By allowing connection to multiple connector types, OWL’s universal
port method minimizes costs and maintenance requirements.
