Mitsubishi Electric Announces Sale of Electroabsorption Modulator Laser Diode Device and Photo Diode Device For 40Gbps Optical Transmission

TOKYO--(Business Wire)--
Mitsubishi Electric Corporation (President and CEO: Setsuhiro
Shimomura) announced today the development of an electroabsorption
modulator laser diode (EAM-LD) device and a photo diode (PD) device,
both for 40Gbps optical transmission. The 40Gbps EAM-LD device is the
world's first(1) laser module with a laser diode (LD), a
monolithically integrated electroabsorption modulator (EAM) and a
built-in driver IC all in one package, while the PD device realizes
high response at the opposite end. Sample shipment will begin on April
1, 2008.

These devices will be displayed at Optical Fiber Communication
Conference & Exposition (OFC2008) in San Diego on February 26-28,
2008.

(1)As of February 19, 2008.

Aim of Sale

With increased Internet traffic in recent years, service providers
have been rushing to expand transmission volume of optical
communication networks. To fulfill the demand for active replacements
of networks to a transmission speed of 40Gbps from the previous
10Gbps, which enable higher optical transmission speed between
metropolitan area networks and routers, transmission equipment
manufacturers are looking for a small and low-priced optical
transceiver that can also be mounted with high-density inside their
equipment.

Meanwhile, the optical output stage inside transceivers involves
LDs, EAMs and their drivers. These three parts had already been
integrated in one package for 10Gbps applications, but not yet for
40Gbps. Optical transceivers for 40Gbps previously installed two
modules: the discrete EAM-LD device and the driver IC. Transceivers
also needed improvement in efficiency when converting optical power
to/from electrical current.

The newly developed laser module is the world's first device with
a built-in driver IC, while the PD device with a built-in
pre-amplifier IC shows improved efficiency compared to previous models
when converting optical power to electrical current. These devices
will make transceivers smaller and lower-priced, thus contributing to
a more high-speed and stable optical transmission at 40Gbps.

Product Features

1) World's first 40Gbps EAM-LD device with built-in driver IC
(FU-642SEA)

The 40Gbps EAM-LD device is the world's first laser module with an
LD, a monolithically integrated EAM and a built-in driver IC, all in
one package. By integrating the discrete transmitter device and their
driver IC, the new laser module realizes stable transmission, while
helping to make transceivers smaller with fewer components. It also
improves optical waveform, which was previously caused due to the use
of coaxial cables for high-frequency connection, thus saving
adjustment time for examination in the production process as well as
reducing other costs.

2) Highly responsive waveguide PD module for high sensitivity
40Gbps detection (FU-342SPP)

Owing to the newly developed waveguide PD with an optical
waveguide shaped detection area, the PD device has a 50 percent
improved efficiency (sensitivity) when converting optical power to
electrical current of 0.9 amperes/watt, compared to previous 40Gbps PD
devices. High sensitivity of this device helps realize stable
transmission.

3) General interface for 40Gbps electrical interface (FU-642SEA,
FU-342SPP)

The dual SMPM connectors for differential operation between
modules and digital signal circuits make system designing easier for
transmission equipment manufacturers.
