SAN JOSE, Calif., March 17, 2020 – NeoPhotonics Corporation (NYSE:
NPTN), a leading developer and manufacturer of silicon photonics and advanced
hybrid photonic integrated circuit based lasers, modules and subsystems for
bandwidth-intensive, high speed optical networks, today announced an L-Band
suite of coherent optical components, including its 64 GBaud L-Band High
Bandwidth Coherent Driver Modulator (HB-CDM), 64 GBaud L-Band Intradyne Coherent
Receiver (ICR) and ultra-narrow linewidth L-Band tunable laser Micro-ITLA. Together with NeoPhotonics standard C-Band
coherent components, these new products enable customers to double the capacity
of optical fiber links.
The C-Band is the primary band for telecommunications with wavelengths centered
around 1550 nm. The L-Band uses
wavelengths centered around 1590 nm and is primarily used to complement the
C-Band to increase data capacity, especially in long-haul networks. By adding channels in the L-Band, operators
can double the capacity of an optical fiber.
NeoPhotonics 64 Gbaud coherent components and tunable lasers enable single
channel 600G data transmission over data center interconnect (DCI) distances of
approximately 80 km using 64 QAM. These
components also support 400G over metro distances of 400-600 km using 64 GBaud
and 16 QAM or 200G over long-haul
distances of greater than 1000 km using 64 GBaud and QPSK.
The NeoPhotonics L-Band External Cavity (ECL) micro-ITLA incorporates the same laser architecture as our
C-Band laser for a pure optical signal with an ultra-narrow linewidth and very
low phase noise. In coherent systems,
any error in the phase of the signal and reference lasers, due to the laser’s
linewidth, can cause data errors, thereby making narrow linewidth critical in
systems using higher order modulation.
The NeoPhotonics 64 Gbaud L-Band HB-CDM co-packages an Indium
Phosphide based Mach-Zehnder (MZ) quadrature modulator chip with a linear,
quad-channel, differential 64 GBaud driver.
Both the C-Band and L-Band versions of the HB-CDM are designed to be compliant
to the Optical Internetworking Forum (OIF) Implementation Agreement
OIF-HB-CDM-01.0 “High Bandwidth Coherent Driver Modulator” (www.oiforum.com).
NeoPhotonics 64 Gbaud L-Band Micro-ICR incorporates an
integrated comixer chip and four balanced photodiodes with four differential
linear amplifiers to provide four output channels at 64 GBaud. The form factor
of the High Bandwidth Coherent Receiver is designed to be compliant with the
OIF Implementation Agreement for Micro Integrated Intradyne Coherent Receivers;
IA # OIF-DPC-MRX-02.0.
For applications that require more capacity than provided by the standard C-Band, but do not require
the full L-Band, each of these components is available in a “C++” version, which supports
tuning across the full “Super C-band” covering 6.0 THz of spectrum or up to 50
percent more than standard systems. These
C++ components can support 80 channels at 75 GHz channel spacing, which effectively
increases the capacity of an optical fiber by as much as 50 percent over
standard C-Band only systems at comparable distances.
"We are pleased to add L-Band versions to our existing suite of
coherent components, thus providing customers with a complete solution to their
fiber capacity requirements, whether C-Band, C++ Band or L-Band,"
said Tim Jenks, Chairman and CEO of NeoPhotonics. "Our ultra-pure tunable laser design and
our high performance coherent modulator and receiver designs are very flexible
and excel in different spectral regimes to provide the highest speed over
distance performance," concluded Mr. Jenks.
