ML9XX11 series are DFB (Distributed Feedback) laser diodes emitting light beam around 1550nm, well suited for light source in long distance digital transmission system. The series products have wide temperature range operation (-40 to 85ºC), low threshold current (typical 8mA), high speed response (typical 0.1nsec) and φ5.6mm TO-CAN package.
The ML9XX11 series are InGaAsP DFB laser diodes designed for ~1.25 Gbps digital transmission systems around 1550 nm. They are hermetically sealed, include a photo‑diode for optical monitoring, and are offered with flat‑window, ball‑lens, or aspherical lens caps.
