COMMUNICATIONS COMPONENTS
2.5 Gb/s Bias-Free Miniaturized Modulator
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
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.
• Medium- and long-haul transmission
• DWDM and TDM transmission
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%.
