1. An apparatus, comprising:

  • a first optical device comprising;

    an illuminating path that directs a first input light beam received from a light source to a first separation channel of a microfluidic chip, the first input light beam causing fluorescent labels attached on DNA fragments in the first separation channel to emit a first fluorescence light, the illuminating path being configured to receive the first input light beam from the light source via an input optical fiber; and

    a detecting path that collects and directs the first fluorescent light to a first plurality of optical fibers;

    a spectrometer configured to receive the first fluorescent light from the plurality of optical fibers and detect fluorescent components in the first fluorescent light; and

    an optical fiber connector configured to connect the first input optical fiber and the first plurality of output fibers with the first optical device, the optical fiber connector being configured to connect the first input optical fiber at a center position, and the first plurality of output fibers around the center position.
