WSP's Fiber Pigtailed PDs use the miniature TO-25 can sealed InGaAs chips coupled with input fibers. The Fiber Pigtailed PDs have high and linear responsivity over wide input power range and wavelength range.
Due to their miniature size, they are ideal for tight space applications and for dense multiple detector assemblies. The fiber pigtailed PDs have a diameter of 3.0mm and a length of 12mm. The PD’s case is electrically isolated from their two leads, which prevents electrical shortage if packed in proximity to conductive materials or when they are assembled as an array.
The choice for fiber type, length, and connectors are flexible per request.
WSP's Fiber Pigtailed PDs have long been used in medical instrumentation, sensing and fiber laser industries, due to their stable and reliable performance.
WSP can provide customized designs to meet specialized applications.
