Fiber-to-Fiber Isolators
The Fiber-to-Fiber Isolator consists of the FiberBench Base with two FiberPorts and two (input & output) FiberCables (distal end is cleaved). mounted on the FiberBench Base are the appropriate Isolator components. OFR will assemble Isolators for the wavelengths listed below. These can include many non-standard wavelengths. Both Polarization Dependent and Polarization Independent Isolators are available. Flexibility in terms of wavelength fine-tuning, or pick-off of returned energy, for example, are possible with OFR FiberBench Isolators.
Available Wavelengths (nm)
     633    780    850    1310
     670    810    980    1550
     690    830    1064

All OFR FiberBench Systems are available in two connector interface options:

FC/APC Connector-Interface
(disconnectable). When ordering, terminate Part Number with -X
Permanent Pigtail, 1-meter.
When ordering, terminate Part Number with -Y.

See In-Line Isolators for smaller package, specific wavelength Isolators, both low and high power.

Polarization Dependent
Catalog Number	Fiber In/Out
IO-G-FFB-λ-X or Y	PM
When ordering, specify wavelength and connector interface: λ: specify wavelength in nm X: specifies connector interface as disconnectable (FC) Y: specifies permanent pigtailed fiber input and output Ex.: IO-G-FFB-850-X All fibers are 1m in length unless otherwise quoted. Distal fiber ends are not connectorized unless requested. Note: that the input plane of polarization must be parallel to the slow axis of the PM fiber (parallel to stress rods).

Polarization Independent
Catalog Number	Fiber In/Out
