SONET (OC-3)/SDH (STM-1) Fiber Optic Receiver Circuit
A light wave receiver circuit for SONET/SDH application at
155 Mbps is shown in Figure 17, with test results given in Table
II. The circuit operates from a single 5 V supply, and uses two
major components: an Epitaxx ERM504 PIN-TIA module with
AGC, and the AD807 IC.
A 120 MHz, third order, low-pass Butterworth filter at the
output of the PIN-TIA module provides adequate bandwidth
(70% of the bit rate), and attenuates high frequency (out of
band) noise.
