FAQ
1. How does the QSFP112 technology differ from previous generations like QSFP28?
A： The QSFP112 technology supports a higher data rate per lane, specifically 112Gb/s per lane, compared to QSFP28 which typically supports lower data rates. This allows for an aggregated bandwidth of 400G in a 4-lane system, making it suitable for next-generation network requirements.
2. Is the 400G QSFP112 Passive DAC cable compliant with industry standards?
A： Yes, the 400G QSFP112 Passive DAC cable is compliant with industry standards such as SFF-8636, SFF8024, and IEEE 802.3ck, as well as the QSFP112 Multi-Source Agreement (MSA).
3. Is the 400G QSFP112 Passive DAC cable suitable for long-distance transmission?
A： No, the 400G QSFP112 Passive DAC cable is designed for short-distance transmission within data centers or between racks and switches. For long-distance transmission, optical fibers or other suitable technologies would be more appropriate.
