The ADN2841 is a dual-loop 50 Mbps to 2.7 Gbps optical transmitter with closed-loop power and extinction ratio control, automatic laser shutdown (ALS), DWDM dual MPD functionality, optional clocked data, full current parameter monitoring and more
The ADN2841 is a dual-loop laser diode driver capable of operating at speeds from 50 Mbps to 2.7 Gbps. It utilizes a unique control algorithm to manage both average power and extinction ratio of the laser diode after initial factory setup, minimizing external component count. The device includes programmable alarms for laser fail and laser degrade conditions, as well as circuitry for a second monitor photodiode to enable DWDM wavelength control.
