- With increasing dependence on secure access to digital services and the ultra-high traffic volumes running on the optical fibre communication infrastructure, the protection of this infrastructure from eavesdropping is extremely important, especially in defense and military applications. The G.657 fibre is recommended to be deployed in in-building installations for its improved bending performance compared to the G.652 fibre. However, the easiness to be eavesdropped, which reflects the security level of those two types of fibres has not yet been investigated. In this paper, we study the eavesdropping of fibre from a system perspective and compare the bending property of G.652 and G.657 fibres. The measurement results show that G.657 can be bent sharper than G.652 without causing any additional power attenuation at the receiver. This indicates that the so-called bending-insensitive G.657 fibre can potentially be eavesdropped more easily than their G.652 counterparts. The paper also shows that the power level measurement at the receiver may not be sufficient for unambiguous eavesdrop detection.

- To support time-sensitive (TS) services with differential low latency requirements, this paper proposes a fine-granularity bandwidth allocation algorithm (FgBA) in higher speed passive optical networks (i.e., ITU-T 50G PON). Simulation results show that FgBA can meet the diverse low latency requirements of TS services regardless of traffic load.

Delay-aware Rate Adjusting Scheme in Higher Speed Passive Optical Networks

Konferensbidrag (refereegranskat)abstract
- Flexible rate is a new desirable operational feature of next-generation higher speed passive optical networks (e.g., ITU-50G PON). In this context, this paper proposes a delay-aware rate adjusting scheme, in which the line rate can be adjusted following the traffic load varying to save energy without degrading delay performance. Simulation results show that the proposed scheme has a similar performance with the benchmark in the aspect of energy saving, while the delay performance of time-sensitive services can be improved significantly, which can be up to 36%.
