NeoPhotonics Announces New Variable Power Intradyne Coherent Receiver (VICR) for High-Capacity 100G Optical Networks
New VICR is Designed to Improve Signal-to-Noise Ratio and Increase
Coincident Channel Count in “Colorless” 100G Coherent Systems
ANAHEIM, Calif.--(BUSINESS WIRE)--Mar. 15, 2013--
NeoPhotonics Corporation (NYSE: NPTN), a leading designer and
manufacturer of photonic integrated circuit, or PIC, based modules and
subsystems for bandwidth-intensive, high speed communications networks,
today announced a new 100G Variable Power Intradyne Coherent Receiver
(VICR). The PIC-based VICR integrates a variable optical attenuator
(VOA) on the signal path and is designed to increase dynamic range and
improve the optical signal to noise ratio (OSNR) for both single channel
and multiple coincident signals. This capability is designed to enable
service providers to better manage network capacity in colorless
coherent networks. NeoPhotonics is currently sampling the VICR and
expects to enter general availability with this product in the second
half of 2013.
Core networks are rapidly moving towards more efficient “colorless”
operation, meaning that ROADM add and drop ports are not limited to
fixed predetermined wavelength channels. Instead, a tunable transmitter
can connect any wavelength to any add port and the ROADM can route any
wavelength to any drop port receiver. Colorless operation improves the
efficiency of valuable line cards and transponders in coherent transport
networks, where a single DWDM channel carries 100Gbps of information.
In coherent optical communications systems the colorless channel drop
operation is enabled by using the local oscillator laser and the VICR to
select the receive channel, eliminating the need for a terminal optical
filter. The VICR then detects the signal channel to which the local
oscillator laser is matched, but all other channels are outside the
device bandwidth. In colorless applications the remaining channels are
not filtered out optically, so the incoming signal power to the VICR can
vary significantly depending on how many other channels are present,
resulting in up to 100 times higher power falling on the receiver than
in the single channel case. The NeoPhotonics VICR integrates a PIC
variable optical attenuator that provides control and stability to the
input signal. In both colorless and conventional optically filtered
systems, the VOA also improves performance by allowing system selection
of the optimal operating point to enhance OSNR and reduce the effects of
optical impairments such as polarization dependent loss (PDL).
“We are pleased to add the VICR to our extensive line of PIC based
intradyne coherent receivers,” said Tim Jenks, Chairman and CEO of
NeoPhotonics. “The VICR illustrates the power of photonic integration to
provide additional functionality to our existing products, which are
designed to benefit our customers with improved performance in the same
form factor and simplified board layouts.”
NeoPhotonics is showcasing the VICR alongside its existing product
portfolio, including other intradyne coherent receivers and narrow
linewidth tunable lasers for 100G coherent communications, its 100G CFP
and CFP2 transponders for client side transmission and an extensive line
of OLT transceivers for FTTH PON networks, at the OFC Exhibition in
Anaheim, California (March 19-21, 2013, Anaheim Convention Center, Booth
1601).
In addition, NeoPhotonics personnel are participating in a workshop and
a panel devoted to PON access applications and presenting a paper on
ROADM-based wavelength agility:
-
Dr. David Piehler, Chief Scientist, Access Products, will discuss the
topic, “Statistical WDM is antifragile,” in Workshop OM1D: Can
Access Networks Afford to be Wavelength Agile?, Monday, March 18th,
9:00 AM - 12:00 PM in Room: 303D. This workshop will examine
architectural and cost considerations in the coming multi-wavelength
PON systems and optical distribution networks (ODN).
-
Also on Monday, 4:00 PM - 6:00 PM in Room: 304C, Dr. Piehler will give
a presentation on “Scaling PON OLT port utilization – HFC style,” in
connection with Panel NM3J: PONs as Used by MSOs. This panel
will consider the role of PON architectures for commercial and
residential services in MSO networks and the timing of PONs in the
residential sector.
-
Dr. Winston Way, Chief Systems Architect, and two co-authors from NEC
Laboratories America, will present the paper: “Contention resolution
within colorless and directionless ROADM,” Wednesday March 20th,
8:00 AM in Room: 304C.
