描述 Description

The D171-Type Photodetector consists of a PIN coupled to a multimode fiber pigail. The device is available in a 4-pin mini-DIL configuration (see Figure 3 and/or Table 1) and is ideal for long-reach (SONET) and other high-speed digital applications.

The D171-Type PIN Photodetector is a rear-illuminated planar diode structure with a low-capacitance active area for maximum responsivity and speed.

This device incorporates the new Laser 2000 manufacturing process from the Optoelectronics Products unit of Lucent Technologies Microelectronics Group. Laser 2000 is a low-cost platform that targets high-volume manufacturing and tight product distributions on all optical subassemblies. This platform incorporates an advanced optical design that is produced on Opto’s highly automated production lines. The Laser 2000 platform is qualified for central office and uncontrolled environments, and can be used for applications requiring high perfomance and low cost.
