| 摘要 |
This disclosure concerns the use of optical limiting materials in devices such as optical transceivers. In one example, a receiver optical subassembly includes a detector element positioned to receive incoming optical signals from an optical fiber. An optical limiting element is positioned between the optical fiber and the detector element so that a received optical signal having a power level exceeding a predetermined limit is attenuated to a predetermined extent prior to being received at the detector element.
