TUCAN addresses the component needs for Customer Premises Equipment (CPE) for high data rate (1 to 10Gb/s) WDM PON access networks. Current optical TDM access networks, such as GPON, operate with a single upstream wavelength and utilise low cost, fixed wavelength lasers at cost levels of less than $10 per laser. To approach these costs for WDM PONs it is essential to develop a universal CPE WDM transmitter that can be used on any network unit, regardless of the operating wavelength, i.e. it must be either ‘colourless’ or tunable. Tunable DBR lasers provide a solution that allows flexibility in system design and hence are a widely applicable and future proof solution. However, the cost, power consumption and wavelength control requirements of currently availableproducts prohibit their use in access links.The project targets the development of a low cost tunable transceiver technology that will be capable of meeting access network cost targets whilst maintaining high performance and reducing power requirements. This will be achieved by targeting the main cost and power consuming elements of current products. Key elements of our strategy include transfer of the control of absolute wavelength to the network, use of monolithic integration of the optical components on to a single chip, thereby simplifying the packaging requirements, and the elimination of thermocoolers. Prototype CPE build will drive the development of the overall module to be compatible with equipment requirements forboth business and residential applications and provide units for system level trials. In this way the project aims to demonstrate both the technical and economic feasibility of tunable DBR laser-based CPE as a key enabler for high bandwidth, long reach FTTH networks.

TUCAN解决了高数据速率（1到10 Gb/s）WDM PON接入网络的客户端设备（CPE）的组件需求。当前的光TDM接入网络（例如GPON）以单个上行波长操作，并且以每个激光器低于$10的成本水平利用低成本的固定波长激光器。为了接近WDM脑桥的这些成本，必须开发一种通用CPE WDM发射机，该发射机可以在任何网络单元上使用，而不管工作波长如何，即它必须是“无色”或可调谐的。可调谐DBR激光器提供了一种允许系统设计灵活性的解决方案，因此是一种广泛适用的未来解决方案。然而，成本，功耗和波长控制的要求，目前可用的产品禁止他们在接入link.The项目的目标是低成本的可调收发器技术的发展，将能够满足接入网络的成本目标，同时保持高性能和降低功耗的要求。这将通过瞄准当前产品的主要成本和功耗要素来实现。我们的战略的关键要素包括绝对波长的控制转移到网络，使用单片集成的光学元件到一个单一的芯片，从而简化了封装要求，并消除热冷却器。原型CPE构建将推动整个模块的开发，以符合商业和住宅应用的设备要求，并为系统级试验提供单元。通过这种方式，该项目旨在证明基于可调谐DBR激光器的CPE作为高带宽，长距离FTTH网络的关键推动者的技术和经济可行性。
