MSA Compatible 100G to 4x25G DAC Cable(1-5m, Passive, QSFP28 to 4xSFP28, 26-30W)

The 100G DAC cable assemblies offer 100G to 4x25G data transmission. The DAC breakout cable provides per channel at 25.78Gbps and an aggregated rate of 100Gb/s. Passive DAC cable assemblies are an excellent alternative to fiber optics. Each QSFP28 and SFP28 port may be addressed by an EEPROM, which would provide product information that could be read or written using the I2C interface.
The passive cable has lengths of 1, 2, 3, 4, and 5 meters. It is compliant with IEEE802.3bj, QSFP28 MSA, SFP28 MSA, SFF-8064, SFF-8402, SFF-8432 and SFF8665. QSFP28 to 4xSFP28 passive copper cable assemblies provide high-performance and cost-effective I/O options, which are ideal for HPCs, 5G/6G networks, and enterprise AI networks.

Questions & Answers

When is the 200G to 4x56G Direct Attach Cable best?
This cable is perfect for data centres, HPC, and cloud networks that need high bandwidth, low latency, and efficient data distribution over many ports.

How do I maintain the 200G to 4x56G Direct Attach Cable?
To ensure peak performance, prevent physical stress on the wire, such as tight bends or excessive tugging. Make sure the connections are clean, free of dust, debris, and corrosion. Regularly inspect the cable for visible symptoms of wear, particularly at the couplings.

What should I do if the cable does not operate properly?
First, make sure that both ends of the wire are correctly joined. Check for any evidence of damage to the cable or connections. If the problem remains, ensure that the devices support 200G and 56G speeds. For more assistance or a replacement under warranty, contact customer service.
