FRD and Transmission Tests Transmission results for 36 m fiber: Theoretical transmission is 85%. Measured transmission in V-band measured as 83% - almost identical to specs FRD results for a 2.5 m long Polymicro FBP 200 micron fiber. • F/3.5 input beam • 2.3% FRD • Same tests for 36 m fiber gives ~1% FRD
