Tokyo, Japan, March 12, 2003 - NEC Corporation
today announced the introduction of new fiber optic transceivers
that will be displayed at the OFC 2003 show in Atlanta. The three
new breakthrough products are:
||The world's first 10Gbps optical transponder with built-in
semiconductor optical amplifier for 80km long-reach
||2.5Gbps SFP transponder for 40km reach applications|
||1.25Gbps E-PON transceiver for optical access
The product features include:
||10Gbps optical transponder with
built-in semiconductor optical amplifier for 80km long- reach
applications. (OD-J8967) |
The product is the world's first 10 gigabit per
second (Gbps) optical transponder capable of long reach transmission
to 80 kilometers that meets the Telcordia OC-192 LR-2b/ITU-T G.691
L-64.2b specification and is compliant with the mechanical and
electrical standards of the 300-pin Multi-Source Agreement (MSA) for
10Gbps optical transponders.
The new 104mm x 89mm x 16mm (4in x 3.5in x .63in)
component is expected to bring about a significant reduction in the
size and cost of long reach transmission systems, as the need for
external optical amplifiers such as erbium-doped fiber amplifiers
(EDFA) or additional passive dispersion compensation devices is
The critical breakthrough in the transponder is a
fully-integrated transmitter module that is comprised of a
modulator-driver chip, an EML chip (electro-absorption modulator
integrated DFB-laser) and Genoa's new second-generation single-chip
linear optical amplifier (LOA), all combined on a common substrate.
The LOA loaded optical module was jointly developed by NEC and Genoa
Corporation (URL: http://www.genoa.com/).
A live demonstration of long reach transmission using
the transponder will be conducted at the upcoming OFC '2003 exhibit
at Atlanta in USA, March 25-27 (Booth#3152).
The new product will be sold worldwide. Volume
production of the product will begin in May, 2003. NEC is targeting
sales of more than 2000 10Gps transceiver module units over the next
||2.5Gbps SFP transponder for 40km reach
applications (OD-J8842) |
This product consists of a compact 2.5 gigabit per
second (Gbps) optical transponder packaged in an SFP (small form
factor pluggable) module, capable of long reach transmission to 40
kilometers that meets the Telcordia OC-48 LR-1/ITU-T G.957 L-16.1
specification and is ideally suited for Metro applications.
The new 56.5mm x 13.5mm x 8.5mm component makes
possible a significant reduction in the size and cost of long reach
The critical breakthrough in the transponder is a
fully-integrated transceiver module that is comprised of a high
sensitivity APD (avalanche photodiode) essential for long distance
transmission, its bias generation circuits and bias control
The new product will be sold world wide. Mass
production of the product will begin in April, 2003. NEC is
targeting sales of the 2.5Gbps to exceed 20,000 units within the
next 2 years.
||1.25Gbps E-PON transceiver for optical
The products are transceiver modules for optical
network unit (ONU) and optical line terminal (OLT), suitable to
Ethernet PON systems. NEC has started sample delivery of these
transceiver modules to PON system equipment vendors.
The critical breakthrough in the transceiver modules is a
fully-integrated transceiver module that is comprised of planar
lightwave circuits with WDM function loaded with a LD and a PD by
our passive alignment technique, essential for mass production at
low cost. The modules are also loaded with a burst-mode transmitter
LSI and a burst-mode receiver LSI designed and developed by NEC for
high speed data transmission at 1.25Gbps.
The new product will be sold world wide. Mass production of the
product will begin in June, 2003. NEC expects to ship more than
150,000 units of all PON transceivers, including existing products,
within a year.
"Conforming transponders that meet the Telcordia OC-192
LR-2b/ITU-T G.691 L-64.2b specification for high-optical-loss 80km,
long reach, applications have been unavailable without external
amplification of the optical signal. By incorporating Genoa's new,
high-power, linear optical amplifier directly into the module, we
overcame this problem." stated Keiichi Takahashi, general manager of
NEC Corporation's Fiber Optic Devices Division. "Our new 10Gbps
optical transponder now enables us to offer approximately 20% less
power consumption, 50% smaller size and lower-cost, than our
conventional ones in a simple, easy-to-use, industry-standard form
"Also conforming SFP transceivers that meet the Telcordia OC-48
LR-1/ITU-T G.957 L-16.1 specification for high-optical-loss 40km,
long reach, applications have been difficult thus far. By
incorporating high sensitivity APD and miniaturization of bias
generation and bias control circuits based on our high density
mounting technology, we overcame this problem," Takahashi commented.
"Our new 2.5Gbps optical transponder now enables us to offer 60%
less power consumption, 75% smaller size and lower-cost, than our
conventional ones in a simple, easy-to-use, industry-standard
"With increasing demand for broadband access networks, the
optical access systems business is expected to grow rapidly. The
Ethernet PON system is one of the most promising systems among
various optical access systems, and is now under standardization
process in the IEEE," Takahashi said. "Our new 1.25Gbps optical
transceivers now offer one of the best solutions as transceivers for
such Ethernet PON systems."
The new products are another example of NEC's quality design and
their addition to NEC's existing lineup is expected to enable NEC to
further expand its optical components sales world wide.
