Upgrading to 40 Gigabit Ethernet on an Existing
10 Gigabit Duplex MMF Infrastructure
Growing data center consolidation, higher-performance servers, and
increasing application density on virtualized servers is driving network
capacity demands to levels previously unimagined. Over the last several
years, data center networks have transitioned from 1 Gbps to 10 Gbps
to accommodate this rapid growth. Yet even the 10-Gbps infrastructure
is becoming overwhelmed by today’s data center requirements, making
the shift to 40 and 100 Gbps inevitable, especially in the network
aggregation layer and core.
However, the 10 Gigabit Ethernet fiber cabling infrastructure found in
most data centers is based on the use of transceivers designed for
duplex MMF (two multimode fiber strands). Since 40 Gigabit Ethernet
multimode solutions require eight fiber strands, upgrading is both
expensive and disruptive to the data center.
