46 GBaud Multi-Format Optical Transmitter

OM5110 Datasheet

The OM5110 Multi-Format Optical Transmitter is a C-and L-Band
transmitter capable of providing the most common coherent optical
modulation formats such as PM-QPSK and PM-16QAM up to 46 GBaud.
When combined with a signal source, such as the Tektronix AWG70001A
Arbitrary Waveform Generator or the Tektronix PPG3204 32 Gb/s
Programmable Pattern Generator, the OM5110 offers a complete coherent
optical test signal generation system.

Features and benefits

Multi-format optical transmitter supports modulation of formats such as

Excellent linearity supports modulation of multi-level signals

Modulates single or dual-polarization signals

Built-in C or L-band lasers for setup convenience

Supports external laser sources

Supports manual and automatic bias control of amplifiers and

Remotely control all setup and operations over Ethernet


Testing coherent optical receivers

Golden reference coherent optical transmitter

Transmitter for multi-carrier superchannel systems

100G / 400G / 1Tb/s Coherent Optical Test

The OM5110 Multi-Format Optical Transmitter is a C-and L-Band
transmitter capable of modulating the most common coherent optical
modulation formats such as PM-QPSK and PM-16QAM up to 46 GBaud.
When combined with a signal source, such as the Tektronix AWG70001A
Arbitrary Waveform Generator or the Tektronix PPG3204 32 Gb/s
Programmable Pattern Generator, the OM5110 offers a complete coherent
optical test signal generation system.

For coherent optical transmitter or transceiver manufacturers, the OM5110
may be used as a golden reference against which to compare module
designs. The OM4106D optical modulation analyzer can be used to
measure the performance of a transmitter under development and then
compared against the OM5110 reference transmitter. The flexibility to
automatically or manually set all amplifier and modulator bias points
provides the user the freedom to simulate less-than-ideal performance of
their own device.

Coherent optical receiver manufacturers can also use the OM5110 as the
ideal transmitter with which to test their receiver’s performance and prove
functionality under best-case conditions. Then, using an instrument such as
the AWG70001A Arbitrary Waveform Generator, optical impairments can
be added to the signal to test the receiver under a wide range of real-world

As the demand for network bandwidth has increased, new transmission
schemes such as multi-carrier “superchannels” are under investigation. The
OM5110 can function as the heart of a superchannel system. Multiple
optical carriers can be externally combined and used as the laser source to
the OM5110 using the external signal input. Tektronix offers external laser
sources, such as the OM2012 Tuneable Laser Source, which can be used
to create a superchannel system. With such a configuration, systems with
aggregate data rates such as 400G, 1Tb/s, and beyond, can be created.

The OM5110 offers the convenience of built-in laser sources, either C-band
or L-band. Setup and operation of the laser, such as wavelength and
optical power, can all be controlled remotely over Ethernet. Alternatively, an
external laser source may be connected to the front panel of the instrument
in place of the built-in lasers.

The data from the external signal generator is first amplified by four, high-
linearity amplifiers. The bias points for these amplifiers can be monitored
and automatically controlled by the included Tektronix control software. The
user may also take control of the bias points and set the amplifier bias
voltages manually. The high-linearity of these amplifiers makes them ideal
for multi-level signals such as 16QAM. For two-level signals, such as
QPSK, the amplifiers can be can be driven into saturation so that the
modulator drive is less sensitive to input drive level variations due to
external rf cable losses.

The output of either the on-board laser, or a customer-supplied external
laser is passed through a beam splitter and then fed to each of the four
internal Mach-Zehnder modulators. Like the amplifiers, each Mach-Zehnder
modulator has bias controls that can be automatically controlled or
manually set by the user. The amplified signals feed these four modulators
whose outputs are optically combined to create a complex, dual-polarized
optical signal available on the front-panel of the instrument.

Coherent optical signal generation system

The OM5110 is a key part of a coherent optical signal generation system.
The other major component is the signal generator itself. The Tektronix
PPG3000 series programmable pattern generators and theTektronix
AWG70000 Series Arbitrary Waveform Generators (AWG) offer the
flexibility to choose the type of signal generation instrument suited to the
test requirements.

The PPG3000 Series can generate patterns up to 32 Gb/s and offers 1, 2,
or 4 channels in a single instrument. The patterns may be standard PRBS
patterns or user-defined. Using a 4-channel pattern generator makes
creating dual-polarization I-Q waveforms very simple.

The AWG70000 Series can reach sampling rates as high as 50 GS/s with
10 bits vertical resolution. Such level of performance allows for the direct
generation of IQ basebands signals required by modern coherent optical
communication systems. The arbitrary waveform generation capabilities of
the AWG70000 Series makes it possible to create multi-level signals such
as 16QAM, add impairments to a signal, or to create waveforms that are
precompensated for the real-world effects of the test system.

Coherent optical signal generation is one of the more demanding
applications for an AWG. The requirements in terms of number of channels
sampling rate, bandwidth, record length, and timing and synchronization
quality can be only met by the highest performance instruments, such as
the Tektronix AWG70000 Series. The unique capability of generating ideal
or distorted signals and the ease to add new modulation schemes and
signal processing algorithms without the need to add any extra hardware
make AWGs an ideal tool for coherent optical communication research and
