| COMMUNICATIONS COMPONENTS 2.5 Gb/s Bias-Ready Modulator Butterfly Package Key Features * Designed to work with bias control circuits * Small-outline package * 1530 to 1565 nm operation; L-band versions available * Low drive voltage; compatible with commercial drivers * Low chirp for maximum transmission distance (>1000 km) Applications * Medium- and long-haul transmission * DWDM and TDM transmission Compliance * Telcordia 468 The 2.5 Gb/s bias-ready modulator is a digital device in which the bias point of the interferometer is set using an applied voltage, typically with a control loop, to operate at the half-intensity point (quadrature). This design uses our x-cut technology, which has been field-proven and provides the best stability in the bias point over life. The device provides superior signal quality across a wide range of wavelengths in the C and L bands and can be used to modulate tunable lasers. The modulator is designed for medium- and long-haul transmission in dense wavelength division multiplexing (DWDM) and time division multiplexing (TDM) systems.
