Grid Transmitters are designed for use in optical
transport and high-speed data communication systems
equipped with Wavelength Division Multiplexing (WDM). The
Transmitter features a 1.5 µm EML with an electro
absorptive modulator driver. The device is capable of
640km transmission at 2.5 Gb/s in WDM system.
Transmitter supports the I2C or RS232 serial interface to
communicate with an upper level controller
