The Mitsubishi ML720J11S-03 are DFB (Distributed Feedback) laser diodes emitting light beam with emission wavelength around 1310 nm.
They are well suited for light source in long distance digital transmission systems.
They are hermetically sealed devices with the photo diode for optical output monitoring.

 These are new diodes, individually characterized, in factory envelopes.
