COMMUNICATIONS COMPONENTS 2.5 Gb/s Bias-Free Modulator with Integral Attenuator Key Features Bias-free operation for fast transmitter development and manufacturing Built-in 20 dB variable optical attenuator Single package for less splicing, lower overall insertion loss and more usable board space 1535 to 1565 nm operation; L-band versions available Low drive voltage; compatible with commercial drivers Low chirp for maximum transmission distance (>1000 km) Voltage-controlled lithium niobate attenuator provides proven high reliability Applications Medium- and long-haul DWDM transmission requiring dynamic optical power leveling Transmitters with limite component space The 2.5 Gb/s bias-free modulator with integral attenuator combines a modulator and a 20 dB variable attenuator within one small-outline package, simplifying component count and fiber splicing. The bias point of the interferometer is set to operate at about the half-intensity point (quadrature). A bias control circuit is not required. The attenuator is based on proven integrated optical waveguide technology, making it highly reliable. The modulator provides superior signal quality over a wide range of wavelengths in the C and L bands, and can be used to modulate tunable lasers. These devices are used for 2.5 Gb/s modulation and dynamic power leveling in dense wavelength division multiplexing (DWDM) systems.
