    Abstract: Method and apparatus for producing metal-coated optical fiber involves providing a length of optical fiber having a glass fiber with or without a carbon layer surrounded by a liquid-soluble polymeric coating. The optical fiber is passed through a series of solution baths such that the fiber will contact the solution in each bath for a predetermined dwell time, the series of solution baths effecting removal of the polymer coating and subsequent electroless plating of metal on the glass fiber. The optical fiber is collected after metal plating so that a selected quantity of the metal-coated optical fiber is gathered, Preferably, the glass fiber passes through the series of solution baths without contacting anything except for the respective solution in each.

    Abstract: The invention relates to optical fibers, and systems containing optical fibers. The invention provides an optical fiber that includes a core (110), a cladding (120), a region (130a, 130b, 130c, 130d) and a layer (140) that surrounds and contacts cladding (120). The core (110) enhances pump energy absorption by interacting with pump energy at a desired wavelength and the cladding confines the pump energy at wavelength so that the pump energy can propagate along the fiber and can interact with core (110).

    Abstract: An optical transmission fiber for use in a metropolitan or access network is disclosed. The transmission line includes a fiber being single mode at a first operating wavelength of around 1310 nm and a second operating wavelength of around 1550 nm. The dispersion of the fiber is negative at one of the first and second operating wavelengths and positive at the other of the first and second operating wavelengths, with an absolute value of between about 5 ps/nm/km and 15 ps/nm/km. The fiber also has a zero dispersion wavelength that is located between the first and second operating wavelengths, and an effective area at a wavelength around 1550 nm greater than about 60 mu m . The cabled fiber has a cutoff wavelength less than about 1300 nm. The fiber allows wavelength division multiplexing (WDM) operation in both the bands (1310 nm and 1550 nm) by reducing nonlinear effects such as four-wave mixing (FWM).
