LineSpeed 100G PHY Demonstrations at GigOptix, OIF and MoSys
highlight low-power optical module solution, CFP4 interoperability and
QSFP28 Passive Copper support; and Bandwidth Engine interoperability
with Altera and Xilinx FPGAs enables high performance packet processing

SANTA CLARA, Calif.–(BUSINESS WIRE)–Sep. 17, 2014–
MoSys, Inc. (NASDAQ: MOSY):

Who: MoSys
(NASDAQ: MOSY), a leader in semiconductor solutions that enable fast,
intelligent data access for network and communications systems, is
exhibiting at ECOC
, booth #519. The company will show an extensive array of
technology demonstrations that encompass module applications, line card
applications, and solutions for increased memory bandwidth for packet
processing. Booth demonstrations will include:

1. New MoSys® LineSpeed™
100G Low Power Retimer
(MSH110) private demonstration at MoSys booth

2. MoSys and GigOptix will demonstrate interoperability between the
MoSys® LineSpeed MSH110 PHY and the GigOptix HXT/R6204 Laser Driver and
TIA ICs at GigOptix booth #396. The 100G demonstration will show the
devices combined to deliver a complete loopback of 4 lanes of 25.78Gbps
over more than 100m of multimode fiber. The performance between the
devices was optimized to deliver error-free performance with PRBS-31
traffic across the fiber and highlights the ability of MoSys’ full
duplex retimer and GigOptix’s Transimpedance Amplifier (TIA) and Laser
Driver (LD) to form a solution for VCSEL based applications, such as
100GBASE-SR4. The ultra low-power 700mW retimer and laser driver and TIA
devices support multiple module form factors, including the stringent
size and power envelope requirements of the QSFP28 MSA. The companies
are working together to provide flexible solutions and expect that
future product combinations will make further improvements in power and
address additional optical applications.

3. Optical Internetworking Forum’s (OIF) 2014 interoperability event,
“Accelerating Momentum on the Road to Next-Generation Architectures,”
and related demonstrations will take place at OIF booth #525. The
interoperability event leverages multiple MoSys products and highlights
lowest power and long reach applications:

a. CFP4 100GBASE-LR4 module interoperability leveraging OIFs CEI-28G-VSR
electrical specification with the MSH110 full duplex quad low power

b. CFP4 Active Copper Cable demonstration of MoSys’ full duplex LineSpeed
100G Quad Retimer
(MSH210) for line card applications supporting the
CEI-28G-VSR electrical specification.

c. MoSys QSFP28 passive copper cable demonstration with 4 additional
cable and connector participants interoperating using the OIF CEI-25G-LR
electrical specification over 2, 3, and 4 meters of various gauge (AWG)
copper cable. The cables are connected between two LineSpeed
100G Multi-Mode Gearbox
(MSH310) devices via 25dB+ of insertion loss
including cables, connectors, breakout cards and evaluation boards.

4. MoSys Bandwidth
Engine® IC
interoperability with Xilinx® Virtex®-7 and Altera®
Stratix® V FPGAs at 12.5 Gbps showcasing the capability of MoSys
technology in solving critical packet processing memory transaction
bottlenecks for 100G up to terabit system applications that require
packet intelligence including lookups, statistics, metering and
buffering at these high rates.

What: ECOC
, is Europe’s largest and most established annual show within
the fibre optic communication technology industry and, this year, will
once again showcase the latest products and services while providing an
unrivalled opportunity to meet and network with key suppliers and
industry leaders.

When: ECOC 2014 takes place September 21-25, 2014, Expo is
September 22-24, 2014

Where: Palais des Festivales et des Congrès de Cannes
