| PT-12A * PIN/TIA receiver * High sensitivity, -20 dBm Product Bulletin (Preliminary) * January 2005 * High data rate, up to 12.5 Gb/s * 1200-1650 nm wavelength range * Compact 8-pin butterfly package * SMA or GPO output connector The PT-12A is a -18 dBm sensitivity, single-output receiver module for OC-192/ STM-64 with FEC transmission system receive applications including NRZ with Super FEC up to 12.5 Gb/s. It couples a high responsivity (1.0 A/W), backilluminated PIN photodiode, usable from 1200 nm to 1650 nm, with an internal transimpedance gain stage of 475 V/A. This combination produces a receiver with a 10 GHz band-width and a conversion gain of 475 V/W. The single-coaxial output module is available with either an SMA or GPO output connector in a compact, 8-pin butterfly package with single-mode fiber input. The receiver meets Telcordia GR-468 qualification standards. 1 2 Specifications Wavelength range Bandwidth (-3dB electrical) Low frequency cutoff 1 Sensitivity 2 Overload Group Delay (1 to 10 GHz) Responsivity @ 1550 nm Minimum 1200 9 DC Typical 10 -20 0 Maximum 1650 Units nm GHz kHz -18 40 dBm dBm ps A/W V/W dB 0.8 400 25 1.0 475 -10 Conversion gain Output Return Loss (0.1 to 8 GHz) Optical Return Loss Power dissipation -30 .22 dB W DC Electrical Photodiode voltage Amplifier voltage (VPOS) Amplifier voltage (VNEG) +5 +3.2 -2.1 +8 +3.3 -2.0 +12 +3.4 -1.9 V V V Mechanical Package type Operating temperature Storage temperature Output is DC coupled 10-10 BER, PRBS 223-1 8-pin butterfly with SMA or GPO 0 -40 +70 +85 C C True DC Output Option The PT-12A is available with optional dual power supplies, which enables adjustment and/or stabilization of the DC output to enable accurate extinction ratio measurements.
