Mitsubishi Electric Announces Sale of Transmitter Optical Sub Assembly Laser Modules for 10Gbps/8Gbps SFP+

TOKYO--(Business Wire)--
Mitsubishi Electric Corporation (President and CEO: Setsuhiro
Shimomura) announced today the development of four 1.3-micrometer band
transmitter optical sub assembly (TOSA) laser modules for 10Gbps and
8Gbps optical transmission. The module is small enough to be installed
in an enhanced 8.5 and 10 Gigabit small form factor pluggable module
(SFP+)(1) compliant optical transceiver and operates at low power
consumption and a wide temperature range. Shipment will begin on
February 18, 2008.

(1)A standard for optical transceivers made to unify methods of
Ethernet, fiber channels and other data transmission. Module size is
13.3mm(H) x 13.4mm(W) x 56.5mm(D).

Aim of Sale

Carriers have been rushing to expand metro area fiber optic
communications networks with the recent increase in traffic due to the
spread of ADSL, Fiber To The Home (FTTH), and other high-speed,
large-volume communication services for the residential market.
Similarly, there is a growing demand to increase transmission capacity
in high-speed storage area networks, which also uses optical fiber to
transmit data between storage devices and servers in cases such as
transmitting music, images and other digital contents, or to be used
in high-volume databases for companies.

To further expand transmission capacity in these networks, which
currently use optical transceivers compliant to an industry standard
called 10 Gigabit small form factor pluggable module (XFP), carriers
have been looking for transceivers that are small and operate at low
power consumption with a wide temperature range, thus enabling
high-density installation.

Meanwhile, another standard called SFP+ is being considered, which
uses smaller transceivers with lower power consumption compared to
XFP, and transceiver manufacturers were waiting for the development of
a small-sized pluggable transceiver module to use in their
transceivers.

With a smaller flexible printed circuit (FPC), which is an
electric interface between modules and transceivers, and a highly
efficient laser diode, Mitsubishi Electric's new TOSAs for 10Gbps and
8Gbps enable perfect installation in small optical transceivers
compliant to SFP+.

Product Features

1) Smaller flexible printed circuit, perfect for small SFP+
compliant optical transceivers

Due to the small size of SFP+ compliant transceivers, which has a
40 percent width and 30 percent length compared to XFP, TOSAs needed
further minimization.

While maintaining the 10Gbps miniature device (XMD-MSA)(4)
compatible LC receptacle package, the new module can be installed even
in SFP+ compliant transceivers, due to an 80 percent minimized
flexible printed circuit (FPC).

(4)A unified standard for mechanical and electric interface of
small optical devices installed in XFP.

2) Fast response with low power consumption, operates at wide
temperature range

Previous transceivers used a large amount of electricity to get a
response fast enough for 8Gbps and 10Gbps high-speed transmission.

By using highly efficient distributed feedback (DFB-LD)(5) and
fabry-perot (FP-LD)(6) laser diodes, the new product can operate at
70mA, 20 percent lower than previous modules, thus reducing the
transceivers' power consumption. The module can also operate at a
10-degree higher temperature of 90 degrees C., widening the range of
operating temperature in transceivers.

(5)Mainly used in medium and long distance transmission.

(6)Mainly used in short distance transmission.

Future Developments

Mitsubishi Electric will continue development to further increase
the module's performance and output, and plans to expand the lineup of
these modules.
