MCFCom® multi-core fiber integrates multiple independent cores within a standard 125μm cladding, realizing space division multiplexing (SDM) to multiply transmission capacity without increasing cable diameter. The flagship 4-core product achieves industry-leading attenuation of 0.151 dB/km at 1550nm with inter-core crosstalk below -52dB/100km.
Hengtong has deployed the world's first commercial S+C+L triple-band multi-core fiber cable route, achieving 5x the capacity of conventional single-core fiber, making it the cornerstone technology for next-generation ultra-high capacity networks.
