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.
