The AOC may include an electrical-to-optical PCIe (EO-PCIe) transceiver coupled to the E-PCIe transmitter. The EO-PCIe transceiver may include a laser diode driver that includes a common mode voltage output terminal. The EO-PCIe transceiver may include a detection condition circuit that includes a decoupling capacitor. The decoupling capacitor may be referenced to a ground level and may connect to the common mode voltage output terminal of the laser diode driver. The detection condition circuit may create a receiver detection condition for a receiver detection circuit of the E-PCIe transmitter to detect presence of the AOC."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Detecting presence of active optical cables in peripheral component interconnect-express links","description":"A peripheral component interconnect-express (PCIe) link with presence of an active optical cable (AOC) that couples between an electrical PCIe (E-PCIe) transmitter and an E-PCIe receiver may include t","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9838116","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
