APPLICATION
· ~1.
25Gbps digital transmission system
DESCRIPTION
ML9XX11series are DFB (Distributed Feedback) laser diodes emitting light beam around 1550nm.
They are well suited for light source in long distance digital transmission system.
They are hermetically sealed devices with the photo diode for optical output monitoring.
FEATURES
· Homogeneous grating (AR/HR facet coating) structure DFB · Wide temperature range operation ( -40 to 85ºC ) · Low threshold current (typical 8mA) · High speed response (typical 0.
1nsec) · φ5.
6mm TO-CAN package · Flat window cap, Ball lens cap, or Aspherical lens cap
