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 BPSK, PM-QPSK, and PM-16QAM

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

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 scenarios.

Supports manual and automatic bias control of amplifiers and modulator

Remotely control all setup and operations over Ethernet

OM5110

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.

Datasheet

The data from the external signal generator is first amplified by four, highlinearity 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.

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 development.

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.
