Description
The P172-type receiver consists of a PIN or APD cou- pled to a single-mode or multimode fiber pigtail and a linear preamplifier. Both the PIN and APD are rear-illu- minated planar diode structures with a low-capacitance active area for maximum responsivity and speed. This device incorporates the new Laser 2000 manufac- turing process from the Optoelectronics Products unit of Agere Systems Inc. Laser 2000 is a low-cost plat- form that targets high-volume manufacturing and tight product distributions on all optical subassemblies. This platform incorporates an advanced optical design that is produced on Agere Systems’ highly automated pro- duction lines. The Laser 2000 platform is qualified for central office and uncontrolled environments, and can be used for applications requiring high performance and low cost. Figure 1.

Electrical Characteristics
Minimum and maximum values specified over operating case temperature range and end of life (EOL), and typical values are for 25 °C and beginning of life (BOL), unless otherwise specified * The resistance of the thermistor is inversely proportional to the temperature. The temperature can be calculated from the resistance value using the Steinhart-Hart equation: 1/T = A + B ln(R) + C ln(R)3; where A, B, and C are constants: A = 1.0267 x 10–3, B = 2.565 x 10–4, C = 4.5421 x 10–8.
