Abstract: An example embodiment includes a system for communicating an optical signal. The system includes an optical transmitter and an optical receiver. The optical transmitter includes one or more lasers configured to produce a light signal and a transmitter optical sub assembly (TOSA) receptacle. The TOSA receptacle optically couples the lasers to an optical fiber and launches a quasi-multimode optical signal (quasi-MM signal) that includes at least one lower order mode optical signal and at least one higher order mode optical signal onto the optical fiber. The optical receiver is connected to the optical fiber via a receiver optical sub assembly (ROSA) receptacle. The optical receiver is configured to receive the quasi-MM signal and to substantially block the at least one higher order mode optical signal.

Abstract: A lens arrangement for an LED display device includes a lens. The lens has a first lens surface and an optical axis. The optical axis penetrates the first lens surface of the lens. Furthermore, the lens arrangement includes a transparent transition body, which is firmly coupled with the lens on the first lens surface, which is more temperature-resistant than the lens and which has an optical axis that is parallel to the optical axis of the lens.

Abstract: A WDM ring transmission system is provided having two hubs. Identical groups of optical signals for transmission along the ring are input to both hubs, but one of the hubs includes optical switches for selectively passing one of the groups of optical signals to the WDM ring. Accordingly, if a fault occurs in one of the network-hub connections or one of the hubs becomes defective, the switches couple optical signals from the operational hub to the WDM ring. In addition, optical signals emitted by nodes coupled to the WDM ring are output from both hubs, thereby insuring that signals can be output from, and input to, the ring even if one of the hubs fails.

Abstract: A method for monitoring a plurality of components associated with a communications network node. A diagnostic service signal is generated at an intra-node component and transmitted along a first optical path to another intra-node component where the presence or absence of the signal is detected. In this manner, optical paths defined between intra-nodal components can be monitored using a diagnostic service signal.
