Service providers deploying FTTH network using point-to-multipoint topologies have a fundamental architectural choice to make regarding splitter placement in that network. This involves using centralized (single-stage) or cascaded (multi-stage) splitter configurations in the distribution portion of the network. Both are deployed for a number of reasons according to the desired outcome of the business plan – and both come with their own set of advantages and disadvantages.
There are sometimes advantages to mixing both architectures, creating a hybrid that leverages the advantages of each.
Deploying an FTTH network requires critical architectural decisions, always considering every unique aspect of the business case. The best architecture is the one that meets the requirements and expectations of the provider by reducing CAPEX, optimizing long-term OPEX, and making a future-proof network that can cope with new technologies without dramatic changes.
