Due to the ongoing large increase in bandwidth demand, Data Center connections are expected to move from 25G/100G to 100G/400G.
Within the Data Center Racks
• 10GE still being deployed
• 25GE starting to be deployed in volume
• 100GE (or 50G) will follow
Between Data Center Racks
• 40GE still being deployed
• 100GE starting to be deployed in volume
• 400GE will follow at large Cloud Service Providers
Long Spans/DCI & WAN
• 10G DWDM/Tunable still being deployed
• 100G/200G Coherent starting to be deployed
• 400G Coherent will follow – Then 600G or 800G
Following the market situation, 400G is a priority for the large DC (intra-DC application) and, at a lower scale, for the Telco transmission department.
400G is coming with 2 form factors for the Access/Intra-DC:
*QSFP56-DD (also called QSFP-DD for QSFP Double Density)
*OSFP (for Octal SFP)
Regarding the mainstream form factor of 400G, please see below comparison.
