产品摘要详细参数产品图片

The 2.5 Gb/s bias-free modulator is a digital device in which the bias point of the interferometer is set to operate at about the half-intensity point (quadrature). A bias control circuit is not required. This feature simplifies circuit design and speeds up product development. 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.

As the optical layer extends into the metropolitan and enterprise areas, board real estate is reduced and the component functionality requirement increased. The JDSU miniaturized line of modulators optimizes board space with a footprint reduced by 70%.

Key Features

  • Bias-free operation for fast transmitter development and manufacturing
  • Small - required board space (footprint) reduced by greater than 70% compared with standard butterfly package
  • Printed circuit board (PCB) compatible - single in-line package mounts pins-down
  • 1535 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
