Sumitomo Electric Industries Announces Commercial Production of SFP+ Transceivers

Sumitomo Electric Industries, Ltd. (SEI) (TOKYO:5802)
(ISIN:JP3407400005) today announced a new line of SFP+ transceivers
for 10 Gb/s applications is available in production quantities. The
SPP series is designed to meet IEEE802.3ae and 802.3aq specifications
for 10G Ethernet.

The SFP+ is the next-generation transceiver package for 10 Gb/s
Ethernet and Fibre Channel applications, offering a more compact form
factor than currently offered by the X2 and XFP packages and low power
consumption of less than 1 watt. By removing the clock and data
recovery (CDR) and electronic dispersion compensation (EDC) functions
from the transceiver, the new SFP+ achieves the same size as the
industry-standard SFP form factor now used for data rates up to 4
Gb/s. The SFP+ offers higher mounting densities than current 10G
devices.

Sumitomo Electric Industries is initially releasing three
transceivers in the SPP5000 series:

-- SPP5101SR for 10GBASE-SR using an 850-nm VCSEL for operation
over multimode fiber (MMF) at distances up to 300 m.

-- SPP5101LM for 10GBASE-LRM using a 1310-nm Fabry-Perot laser
for operation over multimode fiber (MMF) at distances up to
220 m.

-- SPP5101LR for 10GBASE-LR using a 1310-nm DFB laser for
operation over single-mode fiber (SMF) at distances up to 10
km.

The SPP5101LM will be demonstrated at the ExceLight/Sumitomo booth
(#2340) during OFC/NFOEC, March 25 - 28 in Anaheim, California.

Sumitomo Electric Industries / ExceLight is an active member of
the SFF-8431 committee, which is responsible for standardizing the
SFP+ transceivers. A final multi-source agreement (MSA) is expected in
May 2007.
