NEC (NEC Corporation, Tokyo, www.nec.com, www.necus.com) An electronics conglomerate known in the U.S. for its monitors. In Japan, it had the lion's share of the PC market until the late 1990s (see PC 98).
NEC was founded in Tokyo in 1899 as Nippon Electric Company, Ltd. FiberOptech, Inc., a subsidiary of NEC USA, 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:
(1) The world's first 10Gbps optical transponder A receiver/transmitter on a communications satellite. It receives a microwave signal from earth (uplink), amplifies it and retransmits it back to earth at a different frequency (downlink). A satellite has several transponders. with built-in
semiconductor optical amplifier A device that boosts light signals in an optical fiber network. Unlike regenerators, which have to convert light to electricity in order to amplify it and then convert it back again to light, the optical amplifier amplifies the light signal itself. for 80km long-reach
(2) 2.5Gbps SFP SFP Small Form-factor Pluggable (optical transceiver module)
SFP Société Française de Physique (French Physics Society; Paris)
Sfp Svenska Folkpartiet (Finnish: Swedish People~s Party) transponder for 40km reach applications
(3) 1.25Gbps E-PON transceiver for optical access applications
The product features include:
1) 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 (Metropolitan Service Area) An urban area with at least 50,000 people plus surrounding counties. There are 306 MSAs and 428 RSAs (rural service areas) in the U.S. MSAs and RSAs are used to allocate cellular licenses. ) 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 (Erbium-Doped Fiber Amplifier) A device that boosts the signal in an optical fiber. Introduced in the late 1980s, the EDFA was the first successful optical amplifier. ) or additional passive dispersion compensation devices is eliminated.
The critical breakthrough in the transponder is a fully-integrated transmitter module that is comprised of a modulator-driver chip, an EML EML - Extended ML. A language for formally specifying SML programs.

Sannella, Proc 3rd BCS/FACS Workshop on Refinement", Springer 1990]. chip (electro-absorption modulator A semiconductor diode that modulates light from a laser that is separate from it, but may be fabricated on the same wafer. Turning the current on causes absorption of the light.

The LOA loaded optical module was jointly developed by NEC and Genoa Corporation (URL URL

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 years.
2) 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 transmission systems.
The critical breakthrough in the transponder is a fully-integrated transceiver module that is comprised of a high sensitivity APD APD atrial premature depolarization (see atrial premature complex, under complex ); pamidronate. (avalanche photodiode Avalanche photodiodes (APDs) are photodetectors that can be regarded as the semiconductor analog to photomultipliers. By applying a high reverse bias voltage (typically 100-200 V in silicon), APDs show an internal current gain effect (around 100) due to impact ionization (avalanche ) essential for long distance transmission, its bias generation circuits and bias control circuits.
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.
3) 1.25Gbps E-PON transceiver for optical access applications (OD-B1222-N21, OD-B1222-L21)
The products are transceiver modules for optical network unit (ONU ONU Organisation des Nations Unies (French: United Nations)

ONU Organizacion de Naciones Unidas (Spanish: United Nations) ) and optical line terminal (OLT), suitable to Ethernet PON (Passive Optical Network) An optical point-to-multipoint access network. There are no optical repeaters or other active devices in a PON, hence the name "passive. 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 (1) (Wavelength Division Multiplexing) A technology that uses multiple lasers and transmits several wavelengths of light (lambdas) simultaneously over a single optical fiber. 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 LSI: see integrated circuit.
(Large Scale Integration) Between 3,000 and 100,000 transistors on a chip. See SSI, MSI, VLSI and ULSI. 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 factor."
"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 min·i·a·tur·ize

min 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 SFP."
"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 (Institute of Electrical and Electronics Engineers, New York, www.ieee.org) A membership organization that includes engineers, scientists and students in electronics and allied fields. ," 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.
These new products will be sold in the U.S. and Canada by WaveSplitter Technologies, Inc.
