OSLO: Dual fiber collimation

Can some one post a layout file for:
1) dual-fiber collimator, one for input and one for output, with 8 degree angled surface;
2) a 8 degree angled GRIN lens (NSG SLW180)
3) a mirror

Adjust the layout file, thus the output beam return back to the output fiber.

The fiber can be SMF-28 corning fiber.

This is a very often used dual-fiber collimation for Telecom fiber optics. Quite a few example use this configuration, such as tilting mirror type VOAs.

Thanks,
YS
