We evaluate location-based methods for the auto-discovery of Shared Risk Link Groups (SRLGs), guided by the topology and design of AT&T’s next generation transport network. Under realistic scenarios, we find the methods extremely effective in identifying SRLGs and associated link diversity relationships. 2000 Optical Society of America OCIS codes: (060.0060) Fiber optics and optical communicat...
The characterization of a Balanced Modulation and Detection analog optical link is presented. The link consists of a pair of low-biased DFB lasers modulated in a push-pull manner and a balanced photodetector. The measured link noise shows an enhancement of 15 dB around the laser threshold and large intermodulation distortion is observed due to imperfections in the half-wave rectification proces...
This paper presents an application of control theory and μ-analysis to stability analysis of optical communication networks. The network transfer matrix representation is used and simplified so that the propagation time-delay is isolated on a link-by-link basis. The optical network stability problem is reformulated as a robust stability problem. Sufficient stability conditions are developed by ...
We experimentally demonstrate and evaluate the performance of an analog signal transmission system with photonic integrated optical vortex emitter and 3.6-km few-mode fiber (FMF) link using orbital angular momentum (OAM) modes. The fabricated photonic integrated device is capable of emitting vector optical vortices carrying well-defined and quantized OAM modes with topological charge l=-2 and 2...
Modulating retro-reflectors (MRR) couple passive optical retro-reflectors with electro-optic modulators to allow free-space optical communication with a laser and pointing/acquisition/tracking system required on only one end of the link. In operation a conventional free space optical communications terminal, the interrogator, is used on one end of the link to illuminate the MRR on the other end...
