Amount of times splice a fibre cable without too much loss?

[link to this post]

FTTP/H how many times can you splice without too much loss? Recently had installed Fibre to the Premises, but the tray linking my connection to exchange had 2 spices in already before it was spliced at the mainifold.

"A splice loss under 0.1 dB is typical." according to Wikipedia wink

Typical cable attenuation at 1310nm 0.35 dB/km so 3 splices are equivalent to an extra km of fibre.

Thank you that does answer my question very well. I just hope that my line will still be OK even with the extra splices which were 0.03 but unsure of splices in the tray. I don't know their measurements.

Lengths of 10km to 20km should pose no particular problems, and if a splice is bad it can be redone, and if subsequently that fibre is bad, one of the spares can be used.

The splicing actually melts the two bits of fibre together.
