摘要： A WDM optical communication system is provided that includes a transmitter and a receiver. An optical fiber transmission path couples the transmitter to the receiver. The transmission path includes at least one repeater having an optical amplifier located therein. A dispersion compensator is disposed at an intermediate point along the transmission path. The intermediate point is located outside of the repeater. The compensator includes a wavelength routing device for dividing a signal having a prescribed bandwidth into a plurality of distinct sub-bands. A plurality of output paths is provided for respectively receiving the plurality of distinct sub-bands. The dispersion compensator also includes a dispersion compensating optical element coupled to each of the output paths. Each dispersion compensating optical element substantially compensates for dispersion at a prescribed wavelength within the bandpass of its respective sub-band. A coupler recombining the distinct sub-bands and couples them back onto the optical fiber transmission path.

摘要： A method for entering a market with high barriers to entry and a plurality of proprietary business elements includes converting at least one of the business elements into a universal business element that can accept a wide variety of inputs from other business elements, while converting a remaining one of the plurality of business elements to commoditized business elements. In addition, a market of a resulting business is limited so that the resulting business straddles a gap between two subdivisions of the market. Thus, a combination of technology and market division enables conversion of otherwise proprietary system to commodity equipment that can work with a wide variety of existing vendor equipment while competing technologically with highly engineered solutions. For example as applied to the undersea telecommunications market, one exemplary embodiment of the present invention employs an optical repeater that can accept any existing submarine cable, in combination with an optical line interface terminal that can accept existing terrestrial terminal equipment. Regarding market division, this embodiment is specifically limited to spans of less than 5000 kilometers, and preferably between 350 and 4000 kilometers, thereby straddling both the long-haul and short-haul markets while providing highly desirable services and capability. By selecting this market segment, the embodiment achieves highly desirable economics without the usual concomitant high engineering costs.
摘要翻译：进入具有高进入门槛的市场和多个专有业务元素的方法包括将至少一个业务元素转换成可以接受来自其他业务元素的各种投入的通用业务元素，同时将剩余的一个的商业元素。此外，由此产生的业务的市场有限，因此产生的业务跨越了市场的两个细分市场之间的差距。因此，技术和市场部门的结合使得可以将其他专有系统转换为可与各种现有供应商设备配合使用的商品设备，同时通过高度设计的解决方案在技术上竞争。例如，如应用于海底电信市场，本发明的一个示例性实施例采用可以接受任何现有的海底电缆的光中继器，其结合可接受现有地面终端设备的光线路接口终端。关于市场划分，该实施例特别限于小于5000公里，优选350至4000公里的跨度，从而跨越长途和短途市场，同时提供非常理想的服务和能力。通过选择这个市场部分，该实施例实现了非常理想的经济性，而没有通常伴随的高工程成本。
