Description

The 60FF-T Fiber-to-Fiber coupler is used for interconnecting two fiber cables. It can be aligned and focused so that fiber cables with non-core centered connectors can be coupled with a low coupling loss and, additionally, the polarization axes can be aligned.

Fiber Couplers
A fundamental component of the Fiber-to-Fiber Coupler is the Laser Beam Coupler, which is the input into the opto-mechanical unit collimating the input radiation and, finally, couples the radiation back into the second fiber cable. The stability of the total Fiber-to-Fiber Coupler is determined by the stability of the laser beam coupler.

Coupling focal length
The best focal length for the 60SMS Laser Beam Couplers used in these systems is f' 11 - 12 mm. If the effective numerical apertures of the two fiber used with this system are different, you have to use two Laser Beam Couplers with different focal lengths.

How to order
For selecting the 60SMS Laser Beam Couplers please refer to the 60SMS Laser Beam Couplers site and select in terms of focal length, wavelength range and connector type.

The complete Order Code is composed as follows:
