Corning, a leader in Fiber optic technology has issued a white paper on Corning® TXF™ Optical Fiber. This innovative Fiber product known as Corning® TXF™ Optical Fiber has been designed to deliver increased reach for terrestrial long-haul networks operating at high data rates. Corning’s TXF™ optical fiber combines both ultra-low-loss and a larger effective area to allow error-free, high-data-rate transmission to be achieved over longer spans and extended reach. TXF fiber is compliant with ITU-T Recommendation G.654.E, a category of advanced fibers for long-haul terrestrial networks with cut-off wavelength shifted to just below the loss minimized C-band region. here is the white paper.
