sinovo telecom QSFP28-DD, QSFP56-DD is addressing the technical challenges of achieving a double-density high speed 200G/400G interface, electrical interfaces will employ eight lanes that operate up to 25 Gbps NRZ modulation or 50 Gbps PAM4 modulation, providing solutions up to 200 Gbps or 400 Gbps aggregate. QSFP-DD can enable up to 14.4 Tbps aggregate bandwidth in a 1U switch slot.
Vertical cavity surface
emitting laser (VCSEL) Several common VCSELs are usually 850nm wavelength,
multimode; they are characterized by low cost (production and processing, test
costs), low power consumption, easy coupling (the spot is close to a circle),
and easy arraying, so CoB process can be used to achieve large-scale
integration Module. Since VCSELs have certain difficulties in achieving high
speeds, it seems that 400G should be implemented as 8x50G PAM4, which is the
form of 8 channels of 25G baud rate plus PAM4 modulation. VCSELs dominate in
applications less than 100 meters (receiving optical modules and active optical
cables) and can further integrate more on-board optical modules (OBOs).
However, VCSELs require multimode fiber and the cost is higher than that of
single-mode fiber. Datacom system manufacturers need to prepare multimode
(below 100 meters) and single-mode (greater than 100 meters) fibers.

Expands on the QSFP28 pluggable form factor, a widely adopted four-lane electrical interface
2×1 stacked integrated cage / connector
Cage design optimizations and module case optimizations enable thermal support of at least 7w per module
QSFP-DD electrical interfaces will employ eight lanes that operate up to 25 Gbps NRZ modulation or 50 Gbps PAM4 modulation, providing solutions up to 200 Gbps or 400 Gbps aggregate
QSFP-DD can enable up to 14.4 Tbps aggregate bandwidth in a single switch slot
applications:
By quadrupling aggregate switch bandwidth while maintaining port density, QSFP-DD will support continuing growth in network bandwidth demand and datacenter traffic
Systems designed with QSFP-DD modules will be backwards compatible, allowing them to support existing QSFP modules and provide flexibility for end users and system designers.
