GIGALIGHT Launches 800G QSFP-DD ACC to Faciliate HPC Data Center and AI High Computational Applications
Shenzhen, China, May 19, 2023 – High-speed copper cable products have natural advantages in cost, power consumption, transmission delay, and failure rate, while active copper cable (ACC) further extends the transmission distance of passive copper cable products. Today, GIGALIGHT launched its first 800G active copper cable product – 800G QSFP-DD ACC, which helps high-speed data centers and AI high-computational applications.
GIGALIGHT 800G-DD ACC follows the QSFP-DD800 MSA and IEEE802.3ck specifications, using 16 pairs of copper cables to support bidirectional transmission of 8 channels at a rate of 112GB/s. Compared to the 2m maximum transmission distance of the 800G QSFP-DD PCC, the ACC extends up to 4m, which meets the cabling needs of typical data center short distance interconnects.
The products features are as follows,

- Shows superior SI performance and excellent consistency in 44GHZ network splitting

- Tested on an 800G network tester with KP4-FEC enabled, it meets the IEEE Auto-Negotiation and Link Training requirements, with a Post-FEC BER <1E-15 and an FEC margin of more than 27%. The entire process FEC Frame Loss Ratio is 0.
- The product adopts a Re-Driver scheme, with the power consumption of about 2.5W and the latency less than 20ns. Balance and signal-to-noise ratio balance are crucial, and the power consumption and delay are far superior to the Re-Timer scheme.
- Utilizing innovative production technology ensures good reliability, and the 800G QSFP-DD ACC 26AWG 4m weighs only about 600g.
GIGALIGHT has now fully opened the 200G/400G/800G QSFP-DD series ACC product samples and plans to launch the OSFP series passive and active copper cable products in the second half of the year. Stay tuned for more updates!

Shenzhen, China, May 9, 2023 – To meet the increasing demand for high-speed transmission, low power consumption, and low insertion loss performance from data centers, communication operators, cloud computing service providers, and large enterprise users, GIGALIGHT today launched the 400G QSFP-DD/QSFP112 DR4++ 10km silicon photonics module, unlocking long-distance performance of silicon photonics.

As an open optical network device explorer, GIGALIGHT has already launched a variety of silicon-based integrated 100G and 400G optical modules for 500m to 10km transmission since the introduction of the 400G QSFP-DD DR4 500m SiPh optical module in 2021. Now, with mature silicon photonics integration technology, the power budget of the SiPh optical module can fully meet the 10km transmission requirements.
The GIGALIGHT 400G QSFP-DD/QSFP112 DR4++ 10km silicon photonics module has the following advantages:
400G QSFP-DD DR++
Compliant with QSFP-DD MSA, supports 8 channels of 50G-PAM4 electrical signals and 4 channels of 100G PAM4 optical signals, and supports dual-fiber transmission up to 10km. The module’s transmit end uses a highly integrated silicon photonics solution, and the receive end uses a PIN detector. OMA RXsen meets -7.1dBm @ 2.4E-4 Pre-FEC 26.5625GBd, and power consumption is less than 10W.
Next-generation 400G module: 400G QSFP112 DR++
Compliant with QSFP112 MSA, supports 4 channels of 112G-PAM4 electrical and optical signals, and supports dual-fiber transmission up to 10km. The module’s transmit end uses a highly integrated silicon photonics solution, and the receive end uses a PIN detector. OMA RXsen meets -7.1dBm @ 2.4E-4 Pre-FEC 53.125GBd, and power consumption is less than 10W.
