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
