The town where I live is having FTTH installed and I'm blogging progress as it's a huge undertaking and brings lots of benifits.

I,ve found developer information online but I woul like to know the difference between a L3 and L4 cabinet ( one cabinet was open and had 48 fibre connections in it, is this a typical Lx)

Green micro duct goes to each Toby and home run back to the cabinet, what is the green and red duct for and are all cabinets connected in some form of data ring.

The above is so I can expand the blog with some form of rough schematic.
