In optical fiber communication, optical module function is very important, and laser driver is used for light emission front, which can realize laser bias and modulation. The laser controller converts the voltage signal into current signal with high speed to modulatelaser and generate high-speed light signal. And then the light signal is coupled to the optical fiber transmission.
In order to meet the different requirements of design, our company has various types of laser controller, such asultra-low noise laser driver, high efficiency laser driver, dual channel mode laser driver, etc. These laser drivers are described below.


(1) Ultra-low noise laser driver
The ATLSXA103 series is designed for driving integrated chips of diode laser. This laser driver has low noise, no heat sink, small volume, etc. According to the difference of the maximumoutput current, it can be divided into 100mA, 200mA, 250mA, 500mA, 1A and other different types.Because of low power consumption, heat sink isn’t generally needed in the use process.

(2) High efficiency laser driver
High efficiency laser driver mainly includes three series: CWD-01-V2-D, ATLS201D and ATLS202. The efficiency of this product can be up to more than 90%, the volume is small, and the current haslarge span: the minimum output current is 1A; the maximum can reach as high as 10A. And the same models can also be used in parallel.

 

(3) Dual channel mode laser driver
Dual channel mode laser driver is divided into LDA1-CP1 and LDA1-CP2. The former is used to drive the P laser, and the latter is used to drive the N laser.
