AGILE OPTICAL COMPONENTS
10 Gb/s Dual Drive Mach-Zehnder (DDMZ) Modulator
Key Features
• Low differential drive voltage, typically 2 V
• Matching electro-optic amplitude and phase responses
• Wide optical bandwidth, compatible with full band
tunable lasers
• 12 GHz electro-optic (E/O) bandwidth
• Single-sided electrical I/O
Applications
• Long reach (LR) and very long reach
(VR) metro networks
• Long haul (LH), ultra long haul
(ULH), and submarine optical
transport networks
• Optical field processing for active
dispersion compensation at the
transceiver
• Duo-binary transmission at 40 Gb/s
• Bandwidth grooming
The JDSU Agile Optical Components family includes modulators, switches,
attenuators and tunable filters. These products provide the basis for spectrally
efficient DWDM transmission utilizing dispersion tolerant modulation, channel
monitoring, wavelength switching, remote power control and dynamic channel
selection. They support a wide range of flexible functionalities at lower
operational expenses for the Agile Optical Network. In addition, we have a
complete line of tunable lasers assemblies and sub-assemblies in our Agile
Transmission Module family.
The 10 Gb/s Dual Drive Mach-Zehnder (DDMZ) modulator is ideally suited for
use in long reach (LR) and very long reach (VR) metro network applications as
well as in long haul (LH) transmission systems. DDMZ modulators have been
specifically designed to yield well-behaved and matching electro-optic amplitude
and phase responses over a broad RF frequency range. They are ideally suited for
the processing of the optical field of a transceiver’s laser. This application can be
useful for active dispersion compensation.
In addition, DDMZ modulators have a wide optical bandwidth. They are compatible
with full band tunable lasers in either C or L band. Their low drive voltages make
them compatible with low power dissipating differential modulator drivers.
For mounting convenience and space efficiency, the DDMZ modulator is packaged
using JDSU’s compact (6-mm high) hermetic packaging technology. For
transceiver integration and mounting efficiency, the entire electrical I/O is located
on one side of the modulator. The RF inputs use GPO-style RF input connectors.
