Description

Fiber Port Clusters are compact, rugged and highly efficient opto-mechanical units that combine and split the combined radiation into multiple output fiber cables with high efficiency and variable splitting ratio.

Exhibition Setup

The exhibition setup demonstrates the working principle of the fiber port cluster 2 -> 6. The setup also shows fiber collimators of different series as well as an attenuator.


First Setup: Working principle of the Fiber Port Cluster 2⇾6

The two input ports are fiber coupled to PM fiber cables. Polarizers define the input polarization which is necessary for a long term stable splitting ratio.
Two photo diodes right after each input port allow for a continuous monitoring of the radiation. The two input sources are superimposed by means of a polarization beam splitter.
Subsequently, the radiation splitting is achieved by using a cascade of rotary half-wave plates in combination with polarization beam splitters. By use of the rotary half-wave plates, almost any desired splitting ratio can be achieved.
At the output ports further polarizers are placed in order to define the radiation at output of the system.

Laser Beam Coupler 60SMS

A fundamental component of the Fiber Port Cluster is the Laser Beam Coupler, which is the input into the opto-mechanical unit collimating the input radiation and, finally, coupling the radiation back into the polarization-maintaining fiber cables. The stability of the total Fiber Port Cluster is determined by the stability of the laser beam coupler. 

Second Setup: Fiber Couplers and Fiber Collimators

The setup shows a wide range of fiber collimators including fiber collimators series 60FC, fiber collimators series 60FC-SF with super-fine thread, fiber collimators 60FC-T with integrated TILT adjusment, fiber collimators series 60FC-E with elliptical beam profile and fiber collimators series 60FC-Q with integrated quarter-wave plate. The adequate fiber collimator or fiber coupler can be found using the Fiber Coupler Product Configurator.
