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.
