Mitsubishi Electric Announces Sale of SFP+ Compliant Driver IC for 10Gbps Direct Modulation Laser Diode

TOKYO--(Business Wire)--
Mitsubishi Electric Corporation (President and CEO: Setsuhiro
Shimomura) announced today the development of a driver IC (ML01720A)
for 10Gbps direct modulation laser diodes (LDs). The new product is
small enough for installation in small optical transmission devices
compliant to Enhanced 8.5 and 10 Gigabit Small Form Factor Pluggable
Module(1) (SFP+), and operates at low power consumption. Sample
shipment will begin on March 1, 2008.

The ML01720A will be displayed at Optical Fiber Communication
Conference & Exposition (OFC2008) in San Diego on February 26-28,
2008.

(1) A standard or a module compliant to the standard for 8.5 and
10Gbps optical transceivers made to unify methods of Ethernet, fiber
channels and other data transmission.

Aim of Sale

While network equipment for fiber optic communication widely uses
10Gbps optical transceivers compliant to an industry standard called
10Gigabit Small Form Factor Pluggable Module(2) (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. Currently, another standard called SFP+ is being
considered, which uses smaller transceivers with lower power
consumption compared to XFP.

Meanwhile, for transmitter optical sub assemblies (TOSAs) and its
driver ICs used in SFP+ compliant transceivers, there is a strong
demand to reduce their power consumption and space to mount on printed
circuit boards. Following the TOSA for SFP+ developed earlier,
Mitsubishi Electric has developed a SFP+ compliant driver IC for
10Gbps direct modulation LDs. It is as small as 4 millimeters x 4
millimeters and operates at low power consumption.

(2) A standard or a module compliant to the standard for 10Gbps
optical transceivers made to unify methods of SONET, SDH, Ethernet,
fiber channels and other data transmission.

Product Features

1) 55 percent reduced power consumption, best when used with
Mitsubishi Electric's TOSA

Power consumption has been reduced by 55 percent compared to our
previous model (ML01618) by using our microwave design techniques on
high-speed operating driver ICs. When used with Mitsubishi Electric's
TOSA for SFP+ (FU-456RDF-6M1), total power consumption of the optical
transmitter block will be reduced to 410 mill watts, only two-thirds
of the maximum limit for SFP+ of 600 mill watts.

2) Reduced mounting space, a 4-millimeter x 4-millimeter package
with its control functions and driver core in one chip

The product is a 4-millimeter x 4-millimeter package, which is the
smallest in the industry that has, in one chip, a driver core,
automatic laser power control loop (APC) and a function that shuts
down automatically to reduce standby power consumption.

Owing to its small size, the driver IC reduces mounting space on
printed circuit boards to 47 percent compared to our previous model
(ML01618), thus allowing further miniaturization of SFP+ optical
transceivers.

3) Operates at wider temperature range with optical output
waveform adjusting function

The rise and fall of optical output waveform largely influences
transmission speed due to low performance of LDs at high temperature.
To avoid speed loss from this, the product has an optical output
waveform adjusting function, which enables operation at 85 degrees C,
a 10-degree higher temperature compared to our previous model
(ML01618).
