“…Owing to the progress of dense wavelength division multiplexing (DWDM) technology using an optical-fiber amplifier, we can exchange large amounts of data at a rate of over 60 Tbit/s [1]. However, it is widely recognized that the maximum transmission capacity of a single strand of fiber is rapidly approaching its limit of about 100 Tbit/s owing to the optical power limitations imposed by the fiberfuse phenomenon and the finite transmission bandwidth determined by optical-fiber amplifiers [2].…”

The evolution of a fiber-fuse phenomenon in a single-mode optical fiber was studied theoretically. To clarify both the silica-glass densification and cavity formation, which have been observed in fiber fuse propagation, we investigated a nonlinear oscillation model using the Van Der Pol equation. This model was able to phenomenologically explain both the densification of the core material and the formation of periodic cavities in the core layer as a result of a relaxation oscillation.

The evolution of both the core melting and fiber fuse phenomena in a single-mode fiber-optic connector was studied theoretically. Carbon black was chosen as a light-absorbent material. A thin absorbent layer with a thickness of 1 m order was assumed to be formed between the fiber end faces in the connector. When a high-power laser operating at 1.48 or 1.55 m was input into the connector, the temperature on the fiber core surface increased owing to heat conduction from the light-absorbent material. The heat flow process of the core, which caused the core to melt or the fiber fuse phenomenon, was theoretically calculated with the explicit finite-difference method. The results indicated that initial attenuation of less than 0.5 dB was desirable to prevent core fusion in the connectors when the input 1.48 m laser power was 1 W. It was found that a core temperature of more than 4000 K was necessary to generate and maintain a fiber fuse.

“…It has been reported recently that using some definite system configurations would show a practical implementation and typical positions of the EDFA and DRA in order to enhance the transmission performance [14]. Also, an ultra wideband hybrid optical amplifier utilizing DRA and C-and extended L-band EDFA amplifiers were shown to realize the 10.8THz total signal bandwidth [15]. Our simulation of a low NF hybrid amplifier in the C-band proposed and studied numerically.…”
