intended installation distances as shown in Table 1. The factory configures the 
FIM-108 units for the required fiber type before shipping. 

Table 1: Maximum Fiber Lengths

Mark or tag the optical fibers when they are pulled, carefully avoiding the fiber 
tip, so that their identity is known at both ends. If there is confusion about the 
identity of the two fibers, shine a flashlight at one end of the fiber and  look for 
light at the other end. 

 WARNING

 

Do not use the FIM-108 optical output to identify cables. 

Never look directly into the end of the optical fiber while either end of the 
system is operating. Even if you do not see visible light, eye damage is possible. 

Inspect the fiber ends and clean them with clean, dry compressed air or with 
Kim-Wipes that have been saturated with isopropyl alcohol. Fingerprints or 
other dirt on the optical connector end surfaces will reduce the received optical 
signal level.
