Moving Forward- Optical Transceiver 400G And Beyond

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.
