1510 nm Transmitter Module
for Supervisory
Channel Applications
PGT 601 06
Description
The transmitter module is intended for use at SDH and SONET bit rates. The
device meets the intention of the ITU-T (G.691) recommendations.
The single silicon IC is used as a laser driver, modulator and automatic power
control. To ensure a proper laser operation over the wide temperature range
and life of operation, the average optical output power is controlled. The
laser bias is externally accessible for monitoring of the performance. A power
alarm is activated when the average optical power cannot be maintained
within specification. A laser shut-down is also provided according to SDH/
SONET requirements.
