To achieve fast link failure detection in all-optical networks, the notion of monitoring-cycle (m-cycle) is introduced. The best known m-cycle construction algorithm (HST [7]) adopts a spanning tree-based approach. In this paper, we propose a new algorithm M-CYCLE to construct a set of minimum-length mcycles (or m-cycles) for more efficient link failure detection. We prove that the performance ...

—In this paper, we propose and prove the scheme by stabilizing the fiber link time delay in the increase of the signal’s (RF) transmitted phase stability. Let radio frequency signals (RF) transmit between the intermediate node and a distal end to obtain the difference of time delay. The faster and smaller proportion of delay fluctuation are eliminated by the piezoelectric fiber stretchers (PZT...

The compensation effects of number of fiber spans and the residual dispersion per span (RDPS) in the combining of dispersion management (DM) and the midway optical phase conjugation on the optical transmission link consisted of the long fiber spans with 94 km of SMF length and -160 ps/nm/km of the dispersion-compensating fiber’s dispersion coefficient for 24 channels x 40 Gbps wavelength divisi...

We report on a simple bidirectional optical link using two InP-based Fabry–Pérot (FP) lasers operating at 1.55μm wavelength as optical transmitter and receiver. Since the emitted light of one FP laser is absorbed by the other when it is reverse biased, no additional photodiode is required. The optoelectronic devices are butt-coupled to single-mode fibers (SMFs). With this configuration, up to 1...

The bursting aggregation assembly in edge nodes is one of the key technologies in OBS (Optical Burst Switching) network, which has a direct impact on flow characteristics and packet loss rate. An optical burst assembly technique supporting QoS is presented through this paper, which can automatically adjust the threshold along with the increasing and decreasing volume of business, reduce the ope...

We present a network control methodology for multi-link optical networks that is based on network utility maximization. Optical networks provide high data transmission rates which require optimal power control algorithms to ensure the proper delivery of the signals. Time-delays may destabilize the control algorithms unless the relationship between the power update rate and the time-delays are w...

Optical communications link have evolved from lengthy fibers to wireless system such as intersatellite transmission system, for which transmission capacity and distance of optical signal are always an important consideration factor to improve the performance of the optical wireless transmission system. This paper investigates the effect of bit rates on link distance. We have taken bit rates fro...

Optical waveguide interconnects are a major component of chip-scale data processing and computational systems. Here, we propose an alternative mechanism based on optical wireless broadcasting links using nanoantennas, which may overcome some of the limitations of nanoscale waveguide interconnects. By properly loading and matching nanoantenna pairs with optical nanocircuits, we theoretically dem...
