NeoPhotonics Touts 400G Transceiver
January 06, 2020
has shipped its new 400G capable ClearLight CFP2-DCO transceiver for end
customer trials. This is the industry's first transceiver module able to
deliver as much as 32 Terabits of capacity per fiber – significantly
higher than today's 200G CFP2-DCO capacity or the emerging 400G CFP2-DCO
capacity– by using internal optics that can support 80 channels of 64
Gbaud data at 75 GHz wavelength channel spacing combined with the latest
generation of 7 nm node DSP (digital signal processing) technology for
superior OSNR and power consumption. This new product effectively
increases the capacity of an optical fiber by as much as 50 percent over
standard systems at comparable distances.
This ClearLight CFP2-DCO is the first in a series of coherent module
solutions based on NeoPhotonics' patented Photonic Integrated Circuit (PIC)
platform, which will enable cloud operators and carriers to create
optical interconnects with significantly greater capacity and density
with reduced complexity in the high-capacity DWDM ("dense wavelength
division multiplex") optical networks used in hyper-scale cloud and
telecom infrastructure applications.
NeoPhotonics ClearLight CFP2-DCO module incorporates several industry
leading coherent solutions from NeoPhotonics in a pluggable module,
including its new extended tuning range Ultra-Narrow Linewidth Tunable
C++ LASER™ Micro-ITLA. It also features the company's leading high
bandwidth 64 Gbaud C++ ICR™ Receiver and C++ CDM™ Modulator. This module
supports tuning across the full "Super C-band" and provides up to 50
percent more spectrum and resulting capacity than standard modules.
The ClearLight CFP2-DCO module tunes to 75 GHz spaced wavelength
channels when operating at 64 Gbaud and 16 QAM to support 400G
transmission in 400ZR and 400ZR+ modes for Cloud DCI (data center
interconnect) and Metro telecom applications. NeoPhotonics also provides
arrayed waveguide gratings for multiplexing and de-multiplexing with
75GHz channel spacings and filter responses optimized for 64 Gbaud
coherent signals, including for "Super C-band" use.
For Long Haul and Regional applications, this CFP2-DCO module utilizes
64 Gbaud and QPSK modulation to deliver 200G per wavelength
transmission. This is made possible by an industry-leading OSNR of less
than 14 dB and enhanced performance to enable substantially longer
reaches than standard 32 Gbaud, 16 QAM systems.
the application requires that a 50 GHz channel wavelength spacing be
used, this CFP2-DCO module can tune over 120 channels and operate at
200G with an OSNR of less than 16 dB, again substantially better than
today's standard CFP2-DCO transceivers. The module is compliant with the
OIF-CFP2-DCO-01.0-Implementation Agreement and has a superior watt per
gigabit performance. The module will also be available in standard
C-band tuning range for applications that do not require the
significantly higher capacity per fiber that this module enables.
"This new module joins our ClearLight™ CFP-DCO transceiver line, which
has been shipping since 2017, and is our first in a series of DCO
Modules for 400G transmission and providing the benefits of extended C++
tuning range. We are pleased to announce these initial shipments of our
ClearLight CFP2-DCO coherent transceiver modules to customers," said Tim
Jenks, Chairman and CEO of NeoPhotonics. "This new series will utilize
our leading 64 Gbaud Silicon Photonics or Indium Phosphide PICs,
together with our new Tunable C++ LASER Micro-ITLA. This will increase
the capacity and distance performance in a network well above that
available in systems today," concluded Mr. Jenks.
