Loss Evaluation of Longer Monitor Channels
Figure 8
shows the monitor channel signal path from the end farthest from the monitor. The
trunk cable is 80m long. Both LC/LC equipment cord and fan-out array cord are 10m long.
Using
SYSTIMAX Solutions Link Loss Calculator, Version 7.1
plug in the following factors: select
a 30 percent TAP, three low-loss MPO connections, one low-loss LC connection, and 100m
“LazrSPEED
®
with InstaPATCH @ 850nm” fiber cable. Using those inputs the maximum loss of
the odd-numbered monitor channels is calculated as 7.73dB.

end of the channel
Provide the calculated maximum losses, monitor channel lengths, and fiber type including
bandwidth grade of MMF (i.e. OM3 or OM4) to the monitor gear company for channel
evaluations when using 70/30 TAP modules.
TAP Installation
Please refer to the
Instruction Sheet
for InstaPATCH 360 TAP modules for detailed installation
information in eCatalog.
InstaPATCH 360 TAP solution should be utilized in conjunction with the InstaPATCH 360
pre-terminated fiber solutions. Due to the insertion losses of field-installable MPOs, it’s not
recommended to use InstaPATCH 360 TAP solution with fiber trunks terminated with field
installable MPOs.
