A device for measuring and testing components of optical networks includes
an optical connector over which an optical cable may be optically
connected to the device's measuring and/or testing equipment; wherein a
first connector element is provided, onto which a complimentary second
connector element, attached to the optical cable or to this connectable
adapter, may be connected to form an optical coupling; wherein the first
connector element is attached to one end of the tubular connection
elements, which is connected at its other end to the connector and is
reversibly and three-dimensionally flexible.
