Gennum and Altera Demonstrate 4x25Gb/s ICs for Next-Generation 100Gb/s Networks

September 19, 2011

Live Interoperability Demo at ECOC 2011 Show Building Blocks for Higher
Density, Lower Power Optical Networks 

BURLINGTON, ON and San Jose, California, Sept. 19, 2011 /PRNewswire/
- Bolstering the ecosystem for next-generation 4x25Gb/s based optical
transceivers, Gennum Corporation (TSX: GND) and Altera
Corporation (NASDAQ: ALTR) today announced they will demonstrate
interoperability of Gennum’s 25-28Gb/s PHY with Altera’s 28Gb/s enabled
Stratix® V GT FPGA in Gennum’s booth (hall 1, booth 1768) at the
European Conference and Exhibition on Optical Communication (ECOC),
September 19-21, in Geneva. This is the first time an FPGA will have
demonstrated interoperability with a PHY at 25Gb/s, which is enabling
the industry’s migration to higher density, lower power, lower cost
optical modules used in 100Gb/s optical networks.

The demonstration will feature Gennum’s GN2425 and GN2426 module clock
and data recovery (CDR) integrated circuits communicating with an
Altera linecard/host-based Stratix® V GT FPGA operating at 25-28Gb/s
over an OIF CEI-28G-VSR compliant electrical link. The link has greater
than 10dB of loss at the Nyquist data rate and is comprised of host
board traces, module board traces and a Molex zQSFP+ interconnect
system. The link exceeds the CEI-28G-VSR IA requirements and is able to
operate at a bit-error-rate (BER) of less than 1E-15.

As global Internet traffic is expected to multiply over the coming
years, significantly more bandwidth will be required, driving the need
for large-scale network upgrades. Gennum’s GN2425 and GN2426, now
in pre-production, are designed to support 25-28Gb/s data streams for
next-generation 100Gb/s pluggable fiber-optic modules, line cards and
direct-attach copper cables using the 25G-QSFP+ and CFP2 form factors.
They provide exceptional jitter performance with low
power consumption. 

By resetting the jitter budgets within the module in both the transmit
and receive directions, Gennum’s CDRs enable robust operation for new
systems such as 100GBASE-LR4 optical modules. In the transmit direction
they drive EML, DML or MZM drivers with very low jitter, allowing
clean, wide-open transmit eyes. In the receive direction they remove
jitter from the recovered optical signals, promoting error-free
reception by a downstream receiver on the host board. The GN2425 and
GN2426 CDRs include the equalization capability demanded of the new
CEI-28G-VSR IA, providing a robust VSR link.

Altera’s high-performance Stratix V GT FPGAs are tailored to support the
most bandwidth-intensive communications systems. Featuring 28Gb/s
integrated transceivers, Stratix V FPGAs deliver the highest system
bandwidth at the lowest power consumption, under 200mW per channel at
28Gb/s. Stratix V GT FPGAs support backplane, optical module and
chip-to-chip applications through four 28Gb/s transceivers, and 66
full-duplex 14.1Gb/s transceivers. The transceivers in Stratix V GT
FPGAs provide the industry’s highest system reliability with the lowest

The live interoperability demo at the Gennum booth (hall 1, booth 1768)
of the 2011 ECOC show in Geneva demonstrates the availability of key
building blocks enabling a system or equipment manufacturer to be able
to begin manufacturing higher density and lower power optical networks.
