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
