We demonstrate a 4 2 2.5 Gb/s cold-start WDM system using a synchronized etalon filter. This system automatically operated its transmitter lasers at the standardized wavelengths of 1547.82 +n 2 0.8 nm (193.686 0n 2 0.100 THz), where n is the channel number, to an accuracy of 1 GHz. The output power of each laser was also adjusted to be 0 6 0.1 dBm simultaneously. Error-free transmission (BER <10 09 ) was achieved within 20 s after turning on the system's power supply.
