  • Patent number: 7169237
    Abstract: A stabilized basic aqueous hydrogen peroxide composition is disclosed. The composition contains about 0.3 wt % to about 15 wt % of hydrogen peroxide; water; and a stabilizer system that contains about 10 ppm to about 1% of a stannate stabilizer; 10 ppm to about 1% of a phosphonic acid chelating agent or a mixture of phosphonic acid chelating agents; and 10 ppm to about 1% of an aromatic chelating agent or a mixture of aromatic chelating agents. The composition comprises less than about 10 ppm pyrophosphate, preferably no pyrophosphate; and has a pH greater than 7.0, preferably about 8.0 to about 10.5.

  • Publication number: 20030147120
    Abstract: A WDM device separates an information signal and a pump power signal, each having a different wavelength from the other, from a combined signal after the information signal has been amplified by a first fiber amplifier stage. The pump power signal is isolated so that is does not co-propagate with the information signal to another fiber amplifier stage, or from an output of the amplifier assembly. The isolated pump power signal is routed to another WDM device that combines this recycled pump power signal and the information signal provided from the first stage. The recycled pump power is used to stimulate dopant of the next stage fiber amplifier to cause amplification of the information signal above the level provided by the first stage.

  • Publication number: 20030067672
    Abstract: A fiber amplifier using a single, general-purpose, fixed, gain-flattening filter to provide a flattened response with respect to wavelength for the C-Band. A feedback loop comprises a micro controller that maintains the amplifier in a selected gain-clamped mode. This facilitates use in a variety of networks that may use a variety of different types and brands of equipment. The micro controller varies the bias current of a first laser pump and a second laser pump in response to input received from an input monitor and an output monitor so that the overall selected composite power gain is maintained.
