OPTICAL FIBER FOR METROPOLITAN AND ACCESS NETWORK SYSTEMS
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 th...

| description | 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 wavelengths and positive at the other wavelength, with an absolute value of between about 5 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 mum2. 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). |
