Multi Core Fibre (MCF)
General Details
Multi core fibre (MCF) is a new kind of fibre with several separate fibre cores co-existed in the same cladding. The MCF can achieve low inter-crosstalk in long SDM (space division multiplexing) optical transmission by adopting the seven-core structure and F-doped cladding, which has a typical promising future in the optical transmission field. The advantage of multi-core fibre is that it can realize transmitting several light signals through different channels over a single fiber.
Features
- Single fibre with spatial superchannels
- Ultra-low cross talk between cores
- Excellent fibre geometric consistency
- Low fibre loss
