Lasers with Polarization-maintaining fiber, in L-band wavelength (156x-1610nm), minumum wavelength is 1570nm normally, but could be lower to 1565nm. Pin-out is type-2 for most 15xxnm signal lasers. See type-1 and type-2 pin-out definition diagram. It is easy to figure out the pin-out type for any 14-pinout laser by laser controller (we use Newport laser controller).
