About this product
Key features
- 【High Speed 100G to 4x25G Breakout Functionality】The 100G QSFP28 to 4x25G SFP28 Direct Attach Copper Cable converts a single 100G QSFP28 port into four 25G SFP28 ports, delivering a stable 25Gbps per channel transmission speed with minimal signal loss,enabling seamless connectivity between 100GbE switches and 25GbE servers/network devices without active components
- 【Superior Passive Design with Low Power Consumption】The 100G QSFP28 to 25G SFP28 direct attach cable is cost-effective,energy-saving solution with no power requirements.Achieve ultra-low power consumption (≤0.1W).Supports data rates up to 25Gbps per channel (100Gbps aggregate) in short distance，ideal for rack-to-rack or intra-rack connections
- 【High Quality 30AWG Twinax Cable for Durability】The 100G QSFP28 DAC is constructed with 30AWG high-purity oxygen-free copper core and a triple-layer shield (aluminum foil + metal wire braid + ground layer), the power cable effectively resists EMI,EMC and RFI in dense wire environment. The reinforced LSZH outer sheath has excellent wear resistance and tensile strength, with a minimum bending radius of 20mm, make it easy to route in narrow cabinet spaces without affecting signal transmission
- 【Advantage of Direct Attach Copper Cable】The 100G QSFP28 to 25G SFP28 direct attach copper cable compare to QSFP+/SFP+ transceiver/fiber optic cable pairs and OAC:no power requirement,no active components,low power consumption,save power and save space,good heat dissipation,good stability, cost savings
- 【Strict quality testing and wide compatible with brands devices】Each passive stack cable undergoes strict factory testing (signal integrity, insertion loss, and return loss tests) to ensure long-term reliability.The DAC direct attach copper compatible with H3C/intel/huawei/cisco/ruijie/tp-link/more other brands

FAQ
How does the breakout work?
The QSFP28 end goes into a 100G switch port set to 4x25G breakout, and the four legs connect to four 25G ports on servers or switches.
What length is it?
4m (13ft) passive copper, longer than typical 1-3m in-rack DACs for adjacent-rack runs.
Will it work with my switch?
It requires a switch that supports 100G-to-4x25G breakout; confirm breakout mode and any required cable coding for your platform.
