    • A switching matrix (30) connects to an access network (10) and a set of at least two operator networks (41). A controller (51) performs a method of establishing new connections across the switching matrix (30) in response to new connection requests. The new connection requests involve a sub-set of the set of operator networks. The controller determines (103) if the new connections can be established across the switching matrix by rearranging only existing connections across the switching matrix to the sub-set of operator networks and, in response, establishes (104) the at least one new connection. Otherwise, the controller rearranges (105) existing connections across the switching matrix to at least one other of the set of operator networks to establish the new connections. The controller (51) minimises the number of other operator networks which are involved when rearranging existing connections. The switching matrix can be a Clos switching matrix.
    • 交换矩阵(30)连接到接入网络(10)和一组至少两个运营商网络(41)。 控制器(51)响应于新的连接请求执行跨越交换矩阵(30)建立新连接的方法。 新的连接请求涉及一组运营商网络的子集。 控制器确定(103)如果通过将仅跨过交换矩阵的现有连接重排到运营商网络的子集合上,跨连接矩阵可以建立新的连接,并且响应地建立(104)至少一个新的连接。 否则,控制器将跨越交换矩阵的现有连接重新排列(105)到该组运营商网络中的至少另一个以建立新的连接。 控制器(51)最小化重新排列现有连接时所涉及的其他运营商网络的数量。 开关矩阵可以是Clos开关矩阵。

    • A node (20) of a wavelength division multiplexed passive optical network (WDM-PON) comprises wavelength division multiplexing optical line termination (OLT) apparatus (22). The OLT (22) has an optical interface (23) for interfacing with a plurality of remote optical network units (11) in a passive optical network using a plurality of different wavelength channels (λ). The OLT (22) has a plurality of electrical first ports (24) corresponding to the optical wavelength channels (λ). A plurality of second ports (33) interface with at least two operator networks (40-42). An electrical switching matrix (30) interconnects the first ports (24) and the second ports (33), allowing any operator (40-42) to access any subscriber in a point-to-point manner. The apparatus at node (20) can be formed as a plurality of modules (25).
    • 波分复用无源光网络(WDM-PON)的节点(20)包括波分复用光线路终端(OLT)装置(22)。 OLT(22)具有用于使用多个不同波长信道(λ)与无源光网络中的多个远程光网络单元(11)进行接口的光接口(23)。 OLT(22)具有对应于光波长通道(λ)的多个电气第一端口(24)。 多个第二端口(33)与至少两个运营商网络(40-42)接口。 电开关矩阵(30)将第一端口(24)和第二端口(33)互连,允许任何操作者(40-42)以点到点的方式访问任何用户。 节点(20)处的装置可以形成为多个模块(25)。
