R192P OC-192/STM-64 Lightwave Receiver
with Improved Sensitivity (–18 dBm)

Description
Receiver Operation
The R192P 10.7 Gbits/s fiber-optic receiver consists of
a high-speed PIN photodetector and a wide-band lin-
ear preamp in a pigtailed, surface-mount metal pack-
age. It is designed for use in single-mode, high-speed
telecommunication applications at the SONET OC-192
and the ITU-T SDH STM-64 data rate of
9.95328 Gbits/s.
At 10.7 Gbits/s, the typical room temperature sensitivity
measured at a BER of 1 x 10^–10 is –17 dBm. The oper-
ating case temperature range for the receiver is 0 °C to
70 °C.
The receiver is manufactured in a compact, 16-pin sur-
face-mount package with a single-mode optical fiber
pigtail. The fiber pigtail is internally beveled for low
return loss and is available with ST, SC, LC, or FC-PC
optical connectors.
The dc levels of the differential outputs can be adjusted
relative to each other for optimum sensitivity in noisy,
amplified systems. These outputs are centered around
a dc level of typically –0.45 V. The TIA requires only a
–5 V power supply for operation. The PIN photodiode
requires a nominal bias voltage of 5 V to 10 V at less
than 1 mA.
