From analyzers to scopes
For its part, Keysight Technologies has recently introduced several optical-test products, including the N4372E 110-GHz lightwave
component analyzer, the N4391B 110-GHz optical modulation
analyzer for terabit coherent communication, and the 110-GHz
Infiniium UXR-Series real-time oscilloscope, according to Dr.
Joachim Peerlings, VP and GM of Keysight's Network and Data
Center Solutions group. He also cited the N77xxC family of optical component test products, the A400G-QDD Layer 1 BERT
and KP4 FEC multiport test system, and the N1092A DCA-M
sampling oscilloscope with integrated clock recovery. He also
mentioned the N4377A lightwave detector, which offers high
speed for frequency-domain and time-domain applications.
"The 110-GHz lightwave component analyzer enables parametric electro-optic S-parameter test of optical receivers and
detectors, transmitters, and modulators targeted for 50 to 100
Gbaud transceivers," he said. "The 110-GHz optical modulation
analyzer solution implements standard-conforming error vector magnitude (EVM) measurements according to ITU G.698.2
and the latest draft of OIF 400ZR standards. It provides high
resolution and low EVM for the testing of 128-Gbaud QAM64
and beyond in 1.2-Tb/s transmission."
All of these products will be on exhibit at OFC, he said, adding that to help customers deal with the complexities, Keysight
will provide at OFC the short courses "Hands-on: Test and
Measurement for Signals with Complex Optical Modulation"
and "Test and Measurement for Data Center/Short Reach
Communications."
Peerlings also noted that in November, Keysight, FormFactor
Inc., and CompoundTek announced they have joined forces to
accelerate integrated photonics (or silicon photonics) innovations. The three companies have jointly developed an advanced
photonics on-wafer testing solution that delivers capabilities
including automated alignment as well as simultaneous optical-optical and optical-electrical device tests, which will be
demonstrated at OFC.
The joint solution, to be offered by CompoundTek, includes
these products:
*	 the FormFactor CM300xi-SiPh, with automated wafer
level photonics positioning combined with Keysight's industry-standard IL/PDL engines and N7700A Photonics
Application Suite (PAS), to support wavelength repeatability
of ±1.5 pm at 2-way sweeps up to 200 nm/s within 1,240
nm to 1,650 nm to ensure accuracy and repeatability from
O-band to L-band;
*	 Keysight's N4373E 67-GHz lightwave component analyzer,
which delivers the necessary bandwidth for both optical
receiver testing and optical transmitter testing with guaranteed specifications for electro-optical S-parameter measurements for device traceability;
*	 Keysight's PathWave software platform, which provides a
consistent user experience as well as common data formats
and control interfaces; and
*	 FormFactor's SiPh software, which enables automated calibrations and alignments and simplifies integration with

Keysight's PathWave software platform, as well as optical
instrumentation, to ensure ease of use.
"Innovation in optics is critical to connect the world and help
the industry to monetize 5G, as well as datacenter and telecom
services," said Peerlings. "Advancing in speed as well as power
and cost efficiency requires a tightly connected ecosystem to
jointly solve the challenges ahead. "
CompoundTek plans to establish a state-of-the-art silicon
photonics testing services hub in Singapore. The company's chief
operating officer, K.S. Ang, commented in a press release, "With
added on-wafer level, automated Si photonics optical/electrical/
RF testing with this solution, customers will be able to limit
packaging costs to avoid module packaging-level testing turnaround time losses. This test solution complements our current
services in mass-production volume with fast cycle-time ..."
"FormFactor's industry-leading silicon photonics wafer test
capability allows our customers to obtain repeatable, consistent
results with unsurpassed throughput," added Claus Dietrich, vice
president and general manager of the Systems Business Unit at
FormFactor. "The system's automated and high-speed calibration and optical alignment, as well as precision measurement
capability in collaboration with Keysight, enable CompoundTek
to offer customers faster time to market."
CompoundTek and FormFactor, as well as Keysight, are
scheduled to exhibit OFC.
