Multi Core Fibre and Module
The multi-core fibre (MCF) is a new kind of optical fibre with several independent fibre cores in the same cladding. The YOFC MCF features a fluorine-doped cladding refractive index profile structure, enabling long-distance space division multiplexing (SDM) optical signal transmission with low crosstalk. This product features a seven-core structure, boasting typical application prospects in the field of optical fibre communication. Based on the SDM concept, the MCF enables the simultaneous transmission of multiple optical signals over a single optical fibre, significantly enhancing communication capacity, and overcoming the transmission capacity limitations of a single-mode fibre.
With the development of SDM technology and multi-core fibre sensing technology, the MCF will be a vital branch of fibre development. The MCF can be customized in terms of the level of crosstalk and fibre coating to meet extensive applications in communication, sensing, industry, and medical treatment.
