New Dual Duplex LC Interface 400G 2xFR4 and 200G QSFP-DD 2xCWDM4 Fan-Out Modules For Data Centers

SINGAPORE - Oct. 31, 2023 - PRLog -- Fiberstamp has unveiled the innovative fan-out optical modules, 400G QSFP-DD 2x FR4 and 200G QSFP-DD 2x CWDM4. The primary goal of these new products is to maximize the development of low-order modulation technology, enhancing optical communication systems' flexibility, efficiency, and cost-effectiveness. This aims to optimize the value of low-order modulation technology within data center and interconnect networks.

The key to this design lies in FIBERSTAMP's exceptional optical design and manufacturing capabilities, with impressive results from this innovative approach. The 400G QSFP-DD 2x FR4 fan-out module utilizes the 8x50G PAM4 CWDM DML technology platform, introducing a distinct interconnection model, unlike the traditional 4x100G PAM4 data center approach. This novel approach offers an economical pathway to upgrading to a 200G FR4 data center network.

400G Data Center Architecture,
DWDM to Spine:

• 400G CFP2/QSFP-DD DCO

Spine to Leaf:

• 400G QSFP-DD 2xFR4 (2x200G)

Leaf to TOR:

• 200G QSFP56 FR4

TOR to Server:

• Option 1: 50G SFP56 PCC/ACC
• Option 2: 200G QSFP56 to 4x50G SFP56
• Option 3: 2x100G QSFP56 AOC/PCC

Furthermore, due to the application of the 50G PAM4 DML technology platform, this module excels in various parameters, including cost structure and power consumption.

Key Product Attributes
