The need for improved security has been widely recognized in the information technology industry, particularly for enterprise storage area networks (SANs). However, until recently there has been relatively little development of threat models which specifically address the unique requirements of these networks. In this paper, we present a method for(More)
This paper presents the results of an independent comparison of security and intrusion detection features implemented in fibre channel fabric switches. These switches are a key element in optical storage area networks. Using an enterprise testbed with mainframe servers and multiterabyte storage, we evaluate four major switch platforms and compare the(More)
There is an emerging need in the computing industry for higher bandwidth, longer distance, and increased density interconnections within clusters of high performance enterprise-class computer systems. Many of these servers share a common set of high level requirements which lend themselves to the use of parallel optical interconnects to either supplement or(More)
Electrooptic and acoustooptic phase gratings perform many useful operations and often compete with each other for similar applications. Using piezoelectric crystals, it is possible to generate a simultaneous acoustoelectro- optic (AEO) grating, which has advantages over applying either effect separately. The AEO effect using surface acoustic waves and(More)
We describe a novel type of failure mechanism for arrays of vertical cavity surface emitting lasers, such as those used in parallel optical interconnects for clustered computer systems. Conventional failure mechanisms related to electrostatic discharge (ESD) during laser manufacturing will cause multiple lasers in an array to fail at once, shortly after the(More)
Optical communication systems based on dense wavelength division multiplexing (DWDM) would benefit from the ability to adjust the operating wavelength of a laser transmitter. Previous attempts, including thermal adjustment, etalon based wavelength locking, and various types of optical frequency and phase locked loops such as the Pound-Drever-Hall technique(More)

This paper describes some of the opportunities for electronic enhancement of fiber optic systems, and presents some new results of device evaluations in this area. Recent standards efforts have turned their attention to data transmission rates of 10 gigabit/second and above for a single data link. This is being driven by a number of factors, including new(More)
The purpose of this work is to investigate the effects of ionizing (gamma) radiation exposure on the bit error rate (BER) of an optical fiber data communication link. While it is known that exposure to high radiation dose rates will darken optical fiber permanently, comparatively little work has been done to evaluate moderate dose rates. The resulting(More)
