Sheet1ch 27 total loss

According to the mid span technology ,I consider that ch27 is fed by individual fiber cableNOCCH25CH24CH23CH27ch28distance loss= cable distance in KM * .34

The total loss = cable distance loss + splicing loss + pigtail loss + adapter loss 1342m887m389m325m263m1- cable distance loss = 2.943 * .34 = 1 db .

2-splicing loss = NOC splice + closure splice + ODC splice

= 3 * .05 = .15 db .

3-pigtail loss = 2 * .2 = .4 db .

4-adapter loss = 2 * .2 = .4 db .

5-safe margin = 3 db .

so total loss = 1 + .15 + .4 + .4 + 3 = 4,95 db .
