When to Use Single-Mode Fiber Attenuators
For 300A operation, single-mod e fib er loss must b e b etween 10d B and  17dB (at 
1300 to 1310 nm). Sinc e saturation may oc c ur if d istanc es are short, attenuators 
may b e req uired  if the total loss on the fib er link is less than 10d B. Perform an
