Figure 7 shows the transmission characteristics of the fiber optics.
Figure 7: Fiber transmission curves.
Both red and blue fiber cables are 25 meters in length. These curves include end reflection losses, but do not include the additional loss (maybe 5-10%) that may be present from the small prism epoxied onto the fiber end. Focal ratio degradation losses are also not included. The focal ratio of the spectrograph collimators are f/6.7 and should collect >95% of the light contained within the output cone of the fibers.
