Usually, the centralized splitting solution is used in the crowded city center or town areas, in order to reduce cost and easy to maintain the optical distributed network (ODN) nodes. A cascaded approach may yield a faster return-on-investment with lower first-in and fiber costs. It is possible to have more than two splitting levels which is called multi-level splitting in a cascaded system, and the overall split ratio may vary (1x16 = 4x4, 1x32 = 4x8, 1圆4 = 4x4x4).Ī centralized architecture typically offers greater flexibility, lower operational costs, and easier access for technicians. In this scenario, there would be an also total of 32 fibers (4x8) reaching 32 homes.
Each of the four fibers leaving this lever 1 splitter is routed to an access terminal that houses a 1x8 level 2 splitter. This is directly connected to an OLT port in the central office. Thus, the PON network connects one OLT port to 32 ONTs.Ī cascaded approach may use a 1x4 splitter residing in an outside plant enclosure. On the other side of the OLT splitter, 32 fibers are routed to 32 customers’ homes, where it is connected to an ONT. The splitter is directly connected via a single fiber to an OLT in the central office. The PON splitting may be achieved by centralized splitting (one-level) or by cascaded splittings (two-level or more).Ī centralized approach typically uses a 1x32 splitter located in a fiber distribution hub (FDH).
It uses a shared optical fiber to connect the central office with a passive optical splitter that is able to accommodate multiple optical connections with customers. It's a point-to-multipoint fiber optical network with no active elements in the signal’s path. The PON is the optical fiber infrastructure of an FTTH network. With the rapid growth of FTTH worldwide, the requirement for larger split configurations (1x32, 1圆4, etc) in these networks has also grown in order to serve mass subscribers, since PLC splitters offer very accurate and even splits with minimal loss in an efficient package, they offer a better solution for today’s FTTH networks than FBT splitters.
Price is lower for small channel splitter
