R192P OC-192/STM-64 Lightwave Receiver

Preliminary Data Sheet, Rev. 4

with Improved Sensitivity (–18 dBm)

June 2001

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

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

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.
