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.
