iv. 0.70 dB/km @ 1550 nm for tight buffered single-mode inside plant cable(e.g.
0.35 dB/km x 10km = 3.5dB)
d. Connector Attn (dB) = number of connector pairs times maximum connector loss in dB
(e.g. 2 connector pairs x 0.20 dB = 0.4 dB loss)
e. Splice Attn (dB) = number of splices times maximum splice loss in (dB) (e.g. 4 splices
x 0.1 dB = 0.4 dB loss)
