Details

  • The 4X100G DR4 optical chip INNOV-TX100D04SNLS01 integrates 4 channels of high-performance MZM modulators and multiple passive components.
  • It adopts a 1:4 optical input form, that is, the laser input is divided into four channels with an optical splitter, enters four high-bandwidth modulators, and couples out the modulated signal through 4 output ports.
  • Each high-bandwidth modulator has a pair of Heaters used to adjust the operating point.
  • At one input optical port and four output optical ports, an MPD is mounted respectively for optical power monitoring.
