Provided are a method and an apparatus for optimizing the performance of an optical transceiver, and the gist is as follows: receiving an optical input and converting the optical input into electrical signals; receiving a performance value and a reference clock of the electrical signals from a DSP part; generating a plurality of clocks by using the reference clock; determining ADC sampling timings of a plurality of ADCs on the basis of phases of the plurality of clocks applied to the plurality of ADCs; and compensating, on the basis of the determined ADC sampling timings, for differences in physical length between output signals of the plurality of ADCs.

Method and apparatus for optimizing performance of optical transceiver

According to an aspect of the present invention, provided is a zeolite catalyst having an MRE structure for hydro-isomerization. The zeolite catalyst has an adsorption volume ratio of lutidine to collidine measured by Fourier-transform infrared spectroscopy (FTIR) using lutidine and collidine as adsorbents of greater than 3 and less than or equal to 10. According to an aspect of the present invention, provided is a method of hydro-isomerization for a hydrocarbon feedstock, including subjecting the hydrocarbon feedstock to a hydro-isomerization reaction under conditions of a temperature of 200° C. to 500° C., a hydrogen pressure of 1 to 200 atmospheres, a liquid space velocity (LHSV) of 1.0 to 10.0 hr, and the hydrogen/feedstock ratio of 45 to 1780 Nm/min the presence of the zeolite catalyst.
