Laser-to-Fiber Isolators
A customer-furnished laser (5.6 or 9.0) is installed on an OFR Laser-to-Fiber Isolator. The Isolator is comprised of a T-E Cooled Laser-to-Fiber Coupling System on which are installed appropriate Isolator components.

OFR Laser-to-Fiber Isolators are available in all wavelengths listed below.  Output fiber is standard PM fiber. Standard SM or MM fibers are available on special order. Please inquire.

A major feature of OFR FiberBench Coupling Systems is stability. Transmittance remains constant after temperature change, shock and vibration far greater than experienced in typical laboratory use.

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.

When ordering, specify wavelength and connector interface:

  • l: laser type 5.6, 9.0 , T03
  • λ: specify wavelength in nm
  • X: specifies connector interface as disconnectable (FC)
  • Y: specifies permanent pigtailed fiber input and output
  • Ex.: IO-P-FTB-5.6-850-X
  • All fibers are 1m in length unless otherwise quoted. Distal fiber ends are not connectorized unless requested.

* Coupling is very dependent upon laser beam characteristics. Circularized lasers have much better coupling effieciency than standard elliptical aspect ratio beams.
