Features

Fiber Pigtailed Models

For applications that require a length of fiber on the input and output of the circulator, choose our pigtailed versions.

Rugged, Compact Bulkhead Design

Newport's No-Tail benchtop circulators incorporate a rugged, encased design utilizing bulkhead connectors rather than loose pigtails to minimize fragile fibers from tangle and excess handling. The lack of fiber pigtails also decreases the optical path delay between the entrance and exit ports, which is an attractive feature for ultra-short pulses and interferometric applications.

Easy Mounting of Benchtop Circulators

Our No-Tail circulators mount easily to optical tables and can withstand frequent handling. Four strong magnets hold the rugged package securely onto steel surfaces. Two countersunk holes, spaced 25.4 mm (1 in.) apart and compatible with mounting patterns of optical tables, provide an additional mounting option.
