Couplers and Collimators (PAF FiberPorts) |
The OFR FiberPort (US Patent 5,638, 472) is an ultra-stable, miniature micropositioner, enabling active alignment of an AR-coated OFR aspheric lens for collimating or for free beam-to-fiber coupling. FiberPorts serve both input and output funtions, and are micro-positionable in six degrees of freedom: 3 linear (x, y, z) 2 angular (azimuth, elevation) 1 rotational (for PM fiber alignment). While performing the same functions as large benchtop 5-axis positioners, the compact size of the Fiber-Port makes it ideally suited for incorporating into shipable OEM equipment, as well as for utility in the development laboratory. A major application for the FiberPort among many laser manufacturers is as the laser interface to an output fiber pigtail.
|
| See page FO-39 for suggested means of mounting a FiberPort to a laser. Final alignment is done on site following simple instructions furnished by OFR. It is the FiberPort’s rugged construction, stability and coupling efficiency that make it popular for this application. The FiberPort is characterized by ultra-stability. Once aligned to maximum coupling efficiency, there is no drift, in spite of temperature changes, shock and vibration beyond that experienced in the normal laboratory. |

NOTE: PAF-X-2, -5 and -7 FiberPorts have a straight FC bulkhead which will work with FC/PC and FC/APC connectors. The PAF-X-11 and PAF-X-15 come with either PC or APC compatable bulkheads please specify which type of connector you will be using when ordering a PAF-X-11 or PAF-X-15 FiberPort.
Ex. To couple a collimated 1mm diameter 633 nm beam into a FC/APC connectorized SM fiber use:
PAF-X-5-VIR.
Ex. To couple a collimated 2.5 mm diameter 1550 nm beam into a FC/PC connectorized SM fiber use:
PAF-X-11-IR-PC.

Interchangeable FiberPort Lenses and Replacement Bulkheads
Normally, the only difference between FiberPorts used in different applications is the lens focal length, usually determined by the application. All FiberPort Lenses are mounted in a Cell that is compatible with all FiberPort models. The Cell positions the principal plane of the Lens at one focal length distance from the polished fiber endface, resulting in collimation. FiberPort Lens Cells are magnetic, and are easily installed and interchanged on site.
Thus, for experimentation purposes, rather than interchanging FiberPorts (containing different focal length lenses), it is more economical to interchange Lenses, mounted in their magnetic Cell, using a single FiberPort.
Bulkhead requirement.
The Bulkhead, the threaded portion on which the Connector attaches, is different in length for the two groups of Lenses as listed below.
FiberPort Lenses LLO-PAF-2,5,7 can be interchanged using FCBH-S Bulkhead. Likewise, LLO-PAF-11,15 use the FCBH-LA. When interchanging Lenses from one group to another, it is not necessary to change FiberPort bodies. It is only necessary to interchange Bulkheads. In summary, interchanging Lenses and Bulkheads is simple, quick and economical.
