摘要： A passive optical network has an optical line terminal (10), passive add drop wavelength multiplexers (20), at different locations along a first optical path, and an optical network termination part (30) coupled to the optical add path and optical drop path of a respective one of the passive add drop multiplexers. The passive add drop wavelength multiplexers are stand-alone parts separate from their respective optical network termination parts, being optically passive, unpowered and having a static configuration of wavelengths. By using such passive ADMs spread along the first optical path acting as a feeder, the PON is no longer limited to a tree structure. Also, the expense of an AWG device can be avoided. By making the ADMs stand-alone passive devices they can be located anywhere, and are non-specific to the types of terminal equipment, so later upgrade or standardisation of the terminal equipment is easier.

摘要： A passive optical network comprises a first node configured to transmit a downlink data signal over a communication channel of an optical link, the communication channel having a first wavelength, and a second node configured to transmit an uplink data signal over the optical link using the communication channel having the first wavelength. The first node and/or the second node is adapted to perform at least one monitoring measurement on the communication channel having the first wavelength, and provide monitoring information, comprising the at least one monitoring measurement, in a monitoring channel. Common public radio interface (CPRI) traffic can therefore be transported over an optical transport network (OTN), by using a frequency reuse technique to provide a symmetrical bi-directional communication link between a first node and a second node, and using a frame structure of the optical transport network to provide a monitoring channel.

摘要： A radio base station (10) has a baseband controller (20) coupled to a radio head (30) by an optical wavelength division multiplexed link to pass downlink signals on a first wavelength (100), and uplink signals on another wavelength (110). A compensating delay is applied to one of the signals to compensate for a difference in transmission times between the downlink and the uplink signals. The compensating delay can be controlled according to the difference in wavelengths. By compensating for such differences in transmission times, synchronisation problems can be avoided or ameliorated, or transmission distances can be increased. This can result in more flexibility in choice of wavelengths, fiber types and fiber lengths, and greater resilience. This can enable simpler installation or configuration, or reconfiguration without needing to take care to restrict the selection of wavelengths on the WDM link or restrict the length of the link for example.
摘要翻译：无线电基站（10）具有通过光波分复用链路耦合到无线电头（30）的基带控制器（20），以在第一波长（100）上传送下行链路信号，并且在另一波长（110）上传送上行链路信号，。对一个信号施加补偿延迟以补偿下行链路和上行链路信号之间的传输时间差。可以根据波长的差异来控制补偿延迟。通过补偿传输时间上的差异，可以避免或改善同步问题，或增加传输距离。这可以在选择波长，光纤类型和光纤长度以及更大的弹性方面产生更大的灵活性。这可以使得更简单的安装或配置或重新配置，而不需要注意限制WDM链路上的波长的选择或限制链路的长度。

摘要： For a WDM ring network, a node has an optical add drop part (60, 62, 64) and a transponder having a wavelength tunable transmitter (20) for sending a selectable one of the wavelengths in a selectable direction around the ring to a destination node. There is a controller (30) configured to select the wavelength to be sent by the wavelength tunable transmitter and to change the direction of sending around the ring, in response to a detection of a fault in sending in one of the directions. By making the transponder colourless and yet able to select direction, a simple protection switching capability can be added to an existing low cost WDM ring network having passive optical filters. This can be achieved without the need for a reconfigurable optical add drop multiplexer and associated control plane.
