MCF, by integrating multiple light-carrying cores within a single cladding, multiplies data throughput without increasing the footprint. In real-world tests, NTT demonstrated transmission speeds exceeding 1 petabit per second using a 12-core fiber over 52.4 km. That’s 10 times faster than traditional single-core systems can deliver under similar conditions.

Meanwhile, HCF breaks the rules of conventional glass-core design. By allowing light to travel through air instead of glass, these fibers nearly eliminate latency and cut signal loss by more than 30%. Research from the University of Southampton has shown that HCF can reduce latency by up to 50% compared to standard fiber — a leap forward for real-time applications such as financial trading and autonomous transport.
