  • Patent number: 10243693
    Abstract: The present invention relates to an optical transceiver using FEC, an optical transceiving system comprising the same, and a remote optical wavelength control method and, specifically, to an optical transceiver using FEC, the optical transceiver comprising: a laser diode driver (LDD) for driving a laser diode (LD) for outputting light; a transmitter optical sub-assembly (TOSA) for transmitting an optical signal received from the LD driver; a receiver optical sub-assembly (ROSA) for receiving the optical signal from the transmitter optical sub-assembly; a micro controller unit (MCU) for controlling the transmitter optical sub-assembly and the receiver optical sub-assembly and analyzing the optical signal; and a forward error correction (FEC) which is controlled by the micro controller unit and generates the optical signal by including, in an overhead excess data frame, control or monitoring request information of a subscriber-side base station.

  • Patent number: 9523079
    Abstract: The present invention involves the use of transcription factors including Tbx5, Mef2C, Hand2, myocardin and Gata4 to reprogram cardiac fibroblasts into cardiomyocytes, both in vitro and in vivo. Such methods find particular use in the treatment of patients post-myocardial infarction to prevent or limit scarring and to promote myocardial repair.
