Pigtail style laser diode to fiber coupler using a 120mW 405nm laser diode with 30% coupling efficiency (30mW minimum output power from the fiber), with a 1 meter long, 900µm OD loose tube jacketed 3/125 polarization maintaining fiber terminated with an FC/APC connector. The coupler return loss is -40dB. The coupler housing includes a 25.4mm x 15mm mounting flange. Driver electronics not included.
