摘要： The techniques described within this disclosure are directed to an in-line adaptor or coupling device of a PON that detects incoming optical signals (e.g., of different services) being delivered over the PON on different bands of wavelengths supported by an incoming optical fiber of the PON, converts (if necessary) any optical signals to suitable wavelength signals, and transmits the converted optical signals to a last mile termination unit via suitable output interfaces. At least a portion of the incoming optical signals are not converted by the in-line adaptor, and instead are passed-through the in-line adaptor to the last mile termination unit via an optical output interface. The in-line adaptor further includes one or more wireless interfaces via which information pertaining to the received optical signals and/or other information related to the in-line adaptor is transmitted to one or more recipient devices.

摘要： Because the reliability of an optical transmission system that uses an optical path switching device is reduced when a configuration is adopted in which the switching state of the optical path in the optical path switching device can be ascertained, this optical path state assessment device has: an optical acceptance unit configured to connect to an optical transmission line through which propagation light propagates in a latter stage of an optical path switching device for switching the path of signal light; an optical spectrum generation unit for generating optical spectrum information of the propagation light; and, a switching state assessment unit for assessing the switching state of the optical path switching device from the optical spectrum information.

摘要： Provided is an optical link. The optical link supports duplex communication of an auxiliary channel for transmitting, between a display source and a display sink, extended display configuration data (EDID) that is related to rendering of the display sink or display port configuration data (DPCD) related to setting of a main link. The optical link is capable of preventing a data transfer error despite a transmission delay or distortion due to non-linearity between an input and an output due to movement of the optical link by setting the main link to be optimized for the optical link, which is different from a request by the display sink with respect to setting of a training pattern, in link training between the display source and the display sink. According to the optical link according to the disclosure, in one-to-multi display in which a plurality of display sinks are connected to one display source, dislocation or instability of the arrangement of a plurality of screens, which may be caused by a change in a connection state of any one display sink, may be prevented, and after the display sink returns to a normal connection state, delay of a video output for the resetting of the main link may be prevented.
