“…In this paper, we elaborate the first single-mode MCF transport network using XT-aware and programmable optical paths with XT monitoring [11]. We use the testbed to demonstrate a traffic engineering use case, in which optical paths are adaptively (re)configured subject to consideration of inter-core XT with the help of an SDN controller.…”

“…With the optical bandwidth spanning the C-band, simple 1-Pbit/s SDM inline amplified transmission can be conducted over a 200-km distance; if the modulation format is set to 8D-16QAM format, the transmission distance can be extended over 1200 km with a capacity of 0.75 Pbit/s. Virtual three-node SDM network experiments were also demonstrated using conventional WSS developed for SMF networks [61].…”

Optical Switching in Future Fiber-Optic Networks Utilizing Spectral and Spatial Degrees of Freedom

Forthcoming capacity scaling requirements of optical networks and advances in optical fiber communications beyond the omnipresent single-mode fiber operating over the conventional band introduces new opportunities and challenges for exploiting the expanded spectral and spatial resources available for fiber-optic network designs. The spectral and spatial degrees of freedom introduce utilization tradeoffs that can be leveraged under different applications. After briefly reviewing the supporting network building elements (emerging fiber types, multiplexers, optical switches, and amplifiers), we consider networking scenarios such as intra/inter datacenter, terrestrial, undersea, and wireless 5G/6G hauling networks and identify the best utilization plan and key attributes that can be harnessed by the offered spectral and spatial degrees of freedom for each scenario and how optical switching can be employed therein for traffic management. Networks supporting these scenarios are Manuscript

“…In order to cope with the increasing need of the internet capacity, space-division multiplexing technique using multicore fibers has been investigated extensively in recent years [6][7][8][9], in which Seven-core fiber (SCF) shows its prospect on future application as one typical multicore fiber [10,11]. Apart from the applications for communication, multicore fiber has attracted a lot of attentions in the area of optical fiber laser and sensors.…”

We proposed a novel torsion sensor based on inter-core mode coupling in seven-core fiber (SCF). The torsion sensor is fabricated by tapering a commercially available SCF spliced with two single mode fibers. Waist diameter and length of the taper structure were experimentally optimized to achieve good transmission spectrum. Based on this structure, the torsion measurement was conducted, and the experimental results demonstrated that the transmission spectrum shows a red shift with the fiber twist. The torsion sensitivity increases with the twisting angle, which can achieve as high as 1.00 nm/°. The direction of wavelength shift was observed to be opposite when twisting the tapered SCF in clockwise and counter-clockwise direction, demonstrating its capability to discriminate the rotation orientation. Moreover, all the measurements were repeated in attempts to confirm its stable performance as well as high accuracy. Mode coupling dynamics and theory of optical anisotropy in twisted fiber are adopted to discuss the sensitivity performance, which agrees well with experimental results. The novel torsion sensor could provide a promising candidate for the applications requiring accurate rotation.
