A single optical cable can only be split into 8 optical fibers
Optical fiber can be split into one or more splitting levels. The recommended number of splitting levels is one (centralized solution) or two (cascade solution). Unlike active devices (which require power), splitters operate without electricity, relying solely on the physics of. In principle, an optical cable can be split, but it's not as simple as just cutting the cable and attaching multiple devices. It is one of the most important elements of all FTTx PON and OLAN networks. In downstream, the optical splitter has the function of a splitter or signal divider allowing. A fiber splitter, also known as a beam splitter, is a passive optical device that splits an optical signal into multiple signals.

Can a multimode 12-core fiber be split into several cores
According to the number of cores, they can be divided into 12 cores, 16 cores, 24 cores, 48 cores, etc. The 12 strand multimode fiber is often used with LED or VCSEL light sources and comes in various grades, including OM1, OM2, OM3, and OM4. These grades represent the cable's performance, with OM4 providing the highest bandwidth capacity and transmission rates. MTP/MPO Trunk fiber optic cables are commonly used to build the main link or horizontal. The MPO (Multi-fiber Push-On) connector is a high-density fiber optic interface designed to support multiple fibers in a single plug. MPO and MTP cables have many attributes in common, which is why both are so popular. Many experts also use MTP connectors because they are exact and dependable.
