Chapter 3 Introduction
3.1. Description
Thorlabs' High-Speed LiNbO
3
Modulator Drivers provide control for fiber-coupled, lithium-niobate, electro-optic
modulators. Depending on the model, each driver is compatible with modulators that can operate at up to speeds
of 12.5 Gb/s or 40 Gb/s. The drivers’ internal circuitry enables bias control with peak, null, and quadrature set
points. The drivers also include a series of power monitors at the laser input, modulator output, and final optical
output, as well as a variable optical attenuator, for fully automatic monitoring and control of optical power along
the entire optical path. The operational wavelength range extends from 1250 nm to 1610 nm (O- through L-band),
and the user may select from power calibration points at 1310 nm, 1550 nm, and 1590 nm using the touchscreen
interface.
The instrument can be controlled in two ways. The simplest method is directly via the built-in graphical user
interface (GUI) and touchscreen. The instrument can also be operated remotely via the RS-232 or USB ports on
the back panel. Remote control is enabled using simple SCPI-type serial commands from a PC. See the remote
control user guide (RCUG), which can be downloaded from
https://www.thorlabs.com/manuals.cfm
, for details.
The most recent firmware and remote control software tool can be downloaded by visiting

and entering the Item # into the search field.
Thorlabs’ technical support can provide up-to-date information on available firmware revisions and control
functions.
NOTE: This manual covers both the
MX10A
and
MX40A
models, as their architectures are very similar.
Differences are clearly noted in the following sections.
3.2. Intensity or Phase Modulators
These drivers can be used for either intensity or phase modulators. For intensity modulators, the unit provides a
full complement of biasing options, both manual and automatic.
However, in the case of phase modulators, the DC biasing circuitry is not needed as it performs no function. In
that case, the user is advised to simply leave the Bias Control functionality turned OFF. All other functions will
operate normally.
3.3. Parts List
Inspect the shipping container for damage. If the shipping container seems to be damaged, keep it until you have
inspected the contents and tested the unit mechanically and electrically. Verify that you have received the
following items within the package:
1. MX10A or MX40A Modulator Driver Main Unit
2. Power Cord According to Local Power Supply
3. 1.25 A, 250 VAC Fuse
4. USB Type A to Type B Cable, 6’ Long
