Isolator Modules
An Isolator module is comprised of a Faraday Rotator with polarizers, mounted on a dowel-pinned base for mounting onto any FiberBench or FiberTable. Isolator Modules are aligned at OFR for the wavelength specified at time of order. The Isolator is polarization dependent. For a description of isolator function, see page IO-2.

Catalog Number	Select Wavelength	Isolation	Insertion Loss	Aperture	Body Type
IOB-3D-λ	633 - 1000 nm	>30 dB	0.4-0.7 dB	3 mm	II (page IO-16)
IOB-3D-λ	1030-1083 nm	>40 dB	0.3-0.5 dB	3 mm	III (page IO-16)
IOB-D-λ	1280-1340 nm	>40 dB	0.1-0.2 dB	1.7 mm	D (page IO-19)
IOB-D-λ	1530-1625 nm	>40 dB	0.1-0.2 dB	1.7 mm	D (page IO-19)
Note: specify wavelength when ordering

Faraday Rotator Modules
The above isolators are available without polarizers to act as Faraday Rotators. Faraday rotation is wavelength dependent so please discuss your application before ordering. A primary application of a Faraday Rotator is in an Isolator or Circulator. Equally important is its use as a Faraday Rotator Mirror in an interferometer or sensor application. As with the Isolators above, the Faraday Rotator module is mounted on the dowel-pinned base for mounting onto any FiberBench or FiberTabe. The Faraday rotators are ordered as: IOB-3D-λ-I, IOB-D-λ-I
