  • Description

    The losses of optical fibers have been reduced to ~0.14dB/km and the fiber count in single small-diameter cables has rapidly increased to ~6,912 in these days. Uncoupled multi-core fibers and few mode fibers with standard cladding diameter for SDM transmission are intensively investigated for practical use. Hollow-core fibers transmitting over a broad wavelength range compete with standard silica fibers with respect to attenuation. Adding new materials into doped fibers shows the potential to expand transmission window beyond the C+L bands. In this workshop, we discuss the emerging technologies of transmission fibers ​and optical amplification that will achieve the next major leap in optical communications.
