[AusNOG] Water in Fibre cables

[XiTatiON]

(sorry not the best picture ever... couldn't find a better one though.)

So basically what happens is a single fiber runs from the OLT to a 
passive splitter that you will find in some of the old Telstra poles and 
pits around the place.  A single fiber is used for TX and RX using 
different wavelengths.

The splitter in the pit or in the pole will then split out to 32 fibers 
that run to houses that connect to the ONT on the premise which then 
provides 4 Ethernet ports and 2 Pots ports which can deliver different 
services...  e.g Ethernet port 1 could be an IINet internet connection, 
Ethernet port 2 could be some kind of IP TV service with Optus, Pots 
port 1 could be a Telstra phone. So it will be 32 homes per unlink back 
to main OLT and FAN sites.

Hope that makes sense.

Regards,

Jon
