PGT 601 07
1620 nm Transmitter Module
for Supervisory
Channel Applications
Key Features
• Provides 1620 nm supervisory channel
laser source for WDM applications
according to ITU-T draft G.691
• Average power control
• Small size (40x70x9 mm)
• CMOS alarm output
• Thermoelectric cooler included
• P-ECL data inputs
• Tone modulation input
• Single 5.0 V supply
Applications
• 1620 nm supervisory channel applica-
tions in WDM systems
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.
