Abstract: A method for determining receiver coupling efficiency includes varying optical power inputted into a half active optical cable to determine a maximum optical power at which the TIA squelches and determining a receiver coupling efficiency by calculating a ratio of a threshold optical power to the maximum optical power at which the TIA squelches. A method of determining link loss in a channel includes varying optical power of a light source to determine the maximum optical power at which the TIA squelches and determining the link loss in the channel by subtracting the maximum optical power from the threshold optical power. A method of determining link topology includes selecting a pattern of optical powers and matching a pattern of squelched and non-squelched outputs with the pattern of optical power. An active optical cable includes memory storing a value related to an initial link loss of the active optical cable.

Abstract: An optical block includes a first surface that receives light entering the optical block, a second surface through which the light exits the optical block, and a reflector that reflects light from the first surface towards the second surface. The reflector includes a textured surface that scatters or absorbs some of the light received from the first surface to attenuate the light exiting the optical block through the second surface.

Abstract: A data transport system for transporting data and auxiliary signals over an optical link comprises a transmitter, a receiver and an optical link. The transmitter and receiver are coupled to a first end of the optical link. The optical link includes a number of optical channels. A controller is coupled to the transmitter and the receiver, and controls the transmitter and the receiver to operate in a first state when data are detected at an input of the transmitter. Data are transported via the data transport system in the first state. The controller controls the transmitter and the receiver to operate in a second state when the data are detected as absent at the input of the transmitter. Data are prevented from being transported via the data transport system in the second state.
Abstract translation: 用于通过光链路传送数据和辅助信号的数据传输系统包括发射机，接收机和光链路。 发射机和接收机耦合到光链路的第一端。 光链路包括多个光信道。 控制器耦合到发射机和接收机，并且当在发射机的输入端检测到数据时，控制发射机和接收机工作在第一状态。 在第一状态下通过数据传输系统传送数据。 当在发射机的输入端检测到数据不存在时，控制器控制发射机和接收机在第二状态下工作。 防止在第二状态下通过数据传输系统传输数据。
