Power-up Data Center Server Interconnection with 800G QSFP-DD PCC

June, 22, 2022 — FIBERSTAMP, the open optical network mail carrier, recently launched groundbreaking passive DAC cable assemblies, 800G QSFP-DD PCC, which breaks another barrier in the 112G PAM4 DAC server interconnection and aims to create an 800G data center.

The globalized consumer trend is becoming sophisticated and leading the expectations of diversification and real-time efficiency gradually increasing, and the usage of globalized data is critically challenging the network capability and storage of data center around the world. However, in developed economic regions where land resources are growing tight, it is extremely difficult for data centers to fulfill the network demands by simply expanding the server size. Therefore, high-density servers are urged to be deployed to enhance the data computing and storage capability of the data center, as well as boosting the efficiency of electricity and cooling systems to reduce the operation cost. Only then can data centers solve the essential problems.

With the benefits of superior reliability, ultra-low power consumption, and cost-effective, FIBERSTAMP’s 800G QSFP-DD PCC is an important cornerstone for constructing next generation of data center servers interconnection. First, 800G QSFP-DD PCC based on 8X100G PAM4 technology the data rate can reach up to 112Gbps per channel which can fulfill the computing and data storage needs of high-performance Big Data. Second, it supports a maximum transmission distance of 2 meters, and both ends of the hot-pluggable QSFP-DD form factor reach industry standards with significant signal integrity performance, boosting server density effectively and easy on-site maintenance and upgrades. Third, with nearly zero power consumption and no heat generated by passive cable, the product is compliant with IEEE P802.3ck D3.0 and QSFP-DD800 MSA HW Rev 6.01. and compatible with QSFP56 and QSFP112 ports, with an insertion loss of less than 19.75dB @26.56GHz. The Channel Operating Margin (COM) is surpassed 3dB under the condition of superimposing 8 near-end crosstalk and 7 far-end crosstalk, even in the test environment using a commercial error tester and MCB, Pre-FEC BER can still perform less than 1E-5 (Post-FEC BER less than 1E-15), which is an extremely portable product to upgrade network equipment for a high-performance data center.


The development of the global digital economy has driven the demand for high-bandwidth networks for different industrial applications such as infrastructure, AI and telecommuting. In this regard, FIBERSTAMP has always been a pioneer and has made great progress in the ecological chain of R&D and the manufacturing f high-speed and high-density DAC cable assemblies. We have declared numerous patents in hardware SI, structure, process and testing, as well as have invested heaovily in the manufacturing process and test automation to improve manufacturability, so as to create a full range of DAC product lines from 10G to 800G for our customers.
