PGT 601 06 1510 nm Transmitter Module for Supervisory Channel Applications Key Features Provides 1510 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 1510 nm supervisory channel applications 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. 1 PGT 601 06 TONE MODULATION DATA P-ECL INPUT OUTPUT DRIVER LASER PACKAGE OPTICAL FIBER LASER SHUT DOWN LASER SAFETY CIRCUIT OUTPUT POWER CONTROL TEMP.
