Loss Evaluation of Shorter Monitor Channels

Figure 7

 shows the monitor channel signal path from the end closest to the monitor. The  

LC/LC equipment cord is 10m long, and the fan-out array cord connected to the monitoring 
port is also 10m long. Using 

SYSTIMAX Solutions Link Loss Calculator, Version 7.1

 plug in the 

following factors: select the 30 percent TAP, one low-loss MPO connection, one low-loss LC 
connection, and 20m “LazrSPEED

®

 with InstaPATCH @ 850nm” fiber cable. Using those inputs 

the maximum loss of the even-numbered monitor channels is calculated as 7.13dB.
