FiberPort for Single-Mode & Polarization-Maintaining Fibers

 

 

 

OFR X-Type FiberPorts use an FC receptacle for FC-connectiorized fibers. For applications requiring non-detachable fiber pigtail, H-Type FiberPorts are also available.
The fiber connecting to a FiberPort terminates in air. To minimize the effects of the resultant back reflection, an FC/APC angle-polished connector is used. On the other hand, with an FC/PC connector or a straight polished connector, there is a-14dB return loss. OFR FiberCables are available in standard FC/APC or optionalFC/PC.

FiberPort for
Multimode Fibers

OFR XM-Type FiberPorts use an FC receptacle for FC-connectorized MM fibers. SMA-Type FiberPorts are for SMA connectorized fibers.
FiberPorts are available for 50§­, 63§­ and 100§­ core diameter, FC-connectorized fibers, and for SMA-connectorized fiber with 50§­, 63§­ and 100-600§­ core diameter.

LAUNCHING A FREE-BEAM INTO PM FIBER. It is critical that fiber and laser polarization axes be aligned when launching into a PM fiber. This task is made much easier if 1/2-Wave Retarder is inserted into the beam.
A FiberBench solution is recommended, with rotatable zero-order 1/2-Wave Retarder for rotation of polarization plane, mounted onto the FiberBench base. Alignment is then a straightforward procedure.

MirrorPorts(Retrace Systems)

The MirrorPort contains a dielectric coated Mirror with >99% reflection. The same precision mechanism used in the FiberPorts and LaserPorts allows ultra fine adjustment of the MirrorPort to assure optimum reverse coupling of the laser beam back into the fiber.
Note that MirrorPorts are inter-changeable, so that other wavelengths can be easily accommodated. OFR MirrorPorts can be assembled as an orthoconjugate retroreflector (Faraday Rotator Mirror).

DetectorPorts

An optional means of measuring intensities is the DetectorPort, which is mounted on a FiberBench or FiberTable. The DetectorPort contains an amplified silion or InGaAs detector (for visible or infrared operation, respectively), whose output voltage is proportional to the average(cw) intensity of light. This voltage is measured using any voltmeter or oscilloscope.

Monitoring laser power in a system is easily done using a DetectorPort on the side of a FiberTable. A Tap Beamsplitter picks off a nominal 4% of the optical beam and directs it to theDetectorPort.
Clearly, it is necessary to have confidence that the tapped-off energy is a true indicator of the laser power. However, if the tap ¡°beamsplitter¡± is a ¡°standard beamsplitter¡±, and if the State of Polarization(SOP) varies, then the tapped-off energy will vary according to changes in SOP. What is needed is a beamsplitter that is not sensitive to SOP. This is OFR's PSP(Polarization-State Preserving) Beamsplitter.
The Tap Beamslitter is mounted on an ACB Base in turn mounted in the beam path on a FiberTable.
