  • Does quantum communication require laying optical cables

    Does quantum communication require laying optical cables

    In this latest demonstration, scientists transmitted these ultra-secure messages over a traditional telecom network without needing to lay new quantum-specific cables, significantly reducing deployment complexity. Northwestern University engineers made a remarkable advance in quantum computing and communication, demonstrating quantum teleportation over a standard fiber optic cable that already carries everyday Internet traffic. What Is Quantum Teleportation ? Quantum teleportation is far removed from the interstellar travel. Researchers at Northwestern University, in Evanston, Ill., have developed fiber optic technology capable of "teleporting" quantum information through the same lines that also carry conventional data traffic.

  • Optical module FEC issue

    Optical module FEC issue

    Optical modules are detected, but the link does not come up. In many cases, the root cause is a FEC mismatch between the two connected devices. FEC, short for Forward Error Correction, is an error-control technology used in high-speed communication systems. At lower network speeds such as 1G or 10G, signal loss and bit errors are. By embedding redundant data that allows receivers to correct errors without retransmission, FEC delivers high-speed performance with low error rates, ensuring both scalability and cost-effectiveness. What Is Forward Error Correction (FEC)? What Is Forward Error Correction (FEC)? Forward Error.
