The need for flexible optical network architectures will increase as network operators attempt to support dynamic bandwidth demands. A very flexible broadband wavelength multiplexer with unique characteristics has been developed for use in flexible optical networks. This technology innovation allows flexible multiplexing of single channel traffic and multi-wavelength traffic onto one fiber. Multi-wavelength traffic spaced 100 Ghz apart modulated at 10 Gb/s is multiplexed while introducing minimal optical impairments. A significant reduction in interchannel crosstalk-like noise generated by interactions of closely spaced channels in multi-wavelength traffic is achieved.

The Defense Fuel Supply Center (DFSC) is responsible for the procurement, transportation, and storage of bulk petroleum products for the U.S. Military Services and Federal Civilian Agencies worldwide. This paper will describe the quality assurance program developed and utilized by the DFSC to prevent quality problems and to ensure specification products are acquired and delivered to its customers. In so doing, it will describe the specification and contract requirements for inspecting jet fuels, marine and automotive diesel fuels, motor gasolines, and heating fuels. The inspection and cleanliness criteria established for shipping containers, such as tankers, barges, tank trucks, railcars, and pipelines, will also be discussed. Additionally, the training and certification of field quality assurance personnel (inspectors) will be reviewed.
