  • Connect the other end of the fiber optic cable to an optical-to-electrical converter module

    Connect the other end of the fiber optic cable to an optical-to-electrical converter module

    Insert one end of the fiber optic cable into the patch panel port. Finally, check the transmit (TX) and receive (RX) paths to ensure that signals are aligned. In high-speed data networks, the seamless integration of fiber optic cables with SFP (Small Form-Factor Pluggable) modules is critical for reliable signal transmission.


  • Upgraded Polish BERT Error Rate Analyzer

    Upgraded Polish BERT Error Rate Analyzer

    Polish version of BERT language model is here! It is now available in two variants: cased and uncased, both can be downloaded and used via HuggingFace transformers library. I recommend.


  • Fiber optic sensor for measuring heart rate

    Fiber optic sensor for measuring heart rate

    In this paper, a rugged, low cost and very efficient fiber optic displacement sensor is proposed and demonstrated for the measurement of amplitude and frequency of heart rate signal. The proposed sensor is based on intensity modulation technique and uses a bundled POF as a probe. Among these sensors, optical fiber sensors (OFSs) stand out due to their remarkable properties, including resistance to electromagnetic interference. Nowadays, wearable devices are gaining broad interest for a continuous monitoring of the heart rate (HR). One of the most promising methods to estimate HR is the seismocardiography (SCG) which allows to record the thoracic vibrations with high non-invasiveness in out-of-laboratory settings.


  • QSFP optical module transmission rate

    QSFP optical module transmission rate

    QSFP data rate ranges from 40G to 800G depending on the module generation. In simple terms, QSFP is not a single speed standard—it is a scalable transceiver form factor used in data centers and telecom networks. For network engineers and procurement managers, the challenge isn't just. The original QSFP+ module supports 4 lanes of 10 Gbps transmission for a total aggregate bandwidth of 40 Gbps. QSFP28 increases the per-lane data rate to 25. Quad Small Form-Factor Pluggable Double-Density (QSFP-DD) offers twice as many high-speed electrical interfaces as QSFP28 while maintaining the same port density.
