摘要	A thermally isolated multi-channel transmitter optical subassembly (TOSA) may be used in a multi-channel optical transceiver. The multi-channel TOSA generally includes an array of lasers optically coupled to an arrayed waveguide grating (AWG) to combine multiple optical signals at different channel wavelengths. The lasers, and possibly other components, are wire bonded to a thermal isolation bar. The thermal isolation bar provides an electrical connection to external circuitry and is thermally coupled to a temperature control device, such as a thermoelectric cooler (TEC). Thus, the thermal isolation bar electrically connects the lasers to the circuitry while preventing external heat from being conducted to the lasers from outside the TOSA. The optical transceiver may be used in a wavelength division multiplexed (WDM) optical system, for example, in an optical line terminal (OLT) in a WDM passive optical network (PON).
其他摘要	热隔离多通道发射器光学子组件（TOSA）可以用在多通道光收发器中。多通道TOSA通常包括光学耦合到阵列波导光栅（AWG）的激光器阵列，以在不同信道波长处组合多个光信号。激光器和可能的其它部件被引线接合到热隔离棒。热隔离条提供到外部电路的电连接并且热耦合到温度控制装置，例如热电冷却器（TEC）。因此，热隔离条将激光器电连接到电路，同时防止外部热量从TOSA外部传导到激光器。光收发器可以用于波分复用（WDM）光学系统中，例如在WDM无源光网络（PON）中的光线路终端（OLT）中。
