We all regularly talk about Fiber to the Premise (FTTP)/Fiber to the Home (FTTH) networks. But, in an era of specialisation, often we only know about the parts that we come into contact with during our working lives - such as the last drop connection, in the case of installers.
So what’s in an FTTP network and how does it work?
In brief, an FTTP network is made up of two main parts:
- The physical layer.
- The active optoelectronics. These can be in the central office, the outside network (if any) and at the customer premise.
The ITU-T standard helpfully defines the extent of a fiber network through the G series of recommendations.
It is G.984.2 that is most relevant here, as it covers GPON networks, and it is PONs I’ll address during this post.
