Multi Core Fibre(MCF)

Multi core fibre(MCF) is a new kind of fibre with several separate fibre cores co-existed in the same cladding. YOFC MCF can achieve low inter-crosstalk in long SDM optical transmission by adopting the seven-core structure and F-doped caldding, which has a typical promising future in optical transmission field. Based on the concept of space division multiplexing (SDM), multi-core fibre can realize transmitting several light signals through different channels and is expected as a breakthrough technology against capacity crunch of optical transmission system over a singlemode fibre. With the development of SDM and multi-core fibre sensor technology, multi-core fibre would be a vital branch of fibre development. The level of crosstalk and fibre coating of MCF can also be customization to fulfill your use in transmission, sensor, industry, medical equipment fields and so on.
