❓ FAQ

A: NETI710 series covers multiple speed grades: NETI710-2CP is a 10G dual-port NIC, NETI710-4CP is a 10G quad-port NIC. We also offer 25G, 100G, 200G, 400G high-speed products to meet different bandwidth requirements from enterprise access to AI training.

A: NETI710 series NICs fully support mainstream operating systems: Linux (RHEL/CentOS/Ubuntu), Windows Server, domestic OS (Kylin/UOS/Zhongke Fangde). We also provide DPDK/SPDK driver support for high-performance computing scenarios.

A: SFP+ ports support up to 10Gbps transmission rate using LC fiber connectors; QSFP+ ports support 4-channel × 10Gbps (total 40Gbps) and can be split into 4 SFP+ ports. Selection depends on switch port type and bandwidth requirements.

A: Yes, high-end models (such as N30/N40/N50/N60 series) support RDMA over Converged Ethernet (RoCEv2) protocol, enabling microsecond-level network latency to greatly improve AI training and distributed storage performance. Some models also support iWARP protocol.

A: NETI710 series NICs support SR-IOV (Single Root I/O Virtualization) and NFVi functions, enabling high-performance networking in virtualized environments. One physical NIC can be virtualized into multiple VFs (Virtual Functions) for use by multiple virtual machines, greatly reducing hardware costs.

A: Mainly check three aspects: 1) PCIe slot compatibility (PCIe 3.0/4.0/5.0); 2) Server BIOS/UEFI settings; 3) Operating system support. It is recommended to provide the server model before procurement, and we can provide compatibility confirmation service.

A: Troubleshooting steps: 1) Check if network cables and fibers are intact; 2) Confirm switch port speed/duplex settings match; 3) Check if NIC driver version is latest; 4) Check for MTU mismatch issues; 5) For RDMA scenarios, check if DCB/QoS is correctly configured. Our technical support team can assist with in-depth troubleshooting.

A: Yes. NETI710-2CP is equipped with two independent SFP+ ports, each port can be independently configured for 10Gbps rate, supporting LACP or active-standby mode to achieve 20Gbps total bandwidth or redundant backup.

A: By transmission distance: 1) Multimode modules (850nm): for short distance up to 300m, lower cost; 2) Singlemode modules (1310nm/1550nm): for long distance 10km-80km. By wavelength, there are also CWDM/DWDM coarse/dense wavelength division multiplexing modules.

A: Mainly depends on transmission distance: 1) 0-300m: choose multimode (850nm) + OM3/OM4 fiber, lowest cost; 2) 300m-10km: choose singlemode (1310nm) + OS2 fiber; 3) Above 10km: choose singlemode (1550nm) + OS2 fiber. For over 40km, please consult technical support.

A: No. SFP+ and QSFP+ are two different specifications: SFP+ supports up to 10Gbps, QSFP+ supports 4×10Gbps (total 40Gbps). Their physical size and interface are completely different and must match corresponding NIC or switch ports.

A: Main factors: 1) Fiber type and quality (OM3/OM4/OS1/OS2); 2) Optical module power and sensitivity; 3) Number of fiber splices and connectors; 4) Optical power budget in the network. It is recommended to reserve 3-5dB margin for aging loss.

A: EZMAX optical modules are fully compatible with mainstream brands such as Huawei, H3C, Ruijie, Cisco, Juniper. We provide the same quality warranty as original modules with more competitive pricing. It is recommended to confirm the device vendor's optical module usage policy.

A: Troubleshooting steps: 1) Confirm optical module model matches port speed (e.g., use SFP+ for 10G ports, not SFP); 2) Check if fiber is damaged or bent excessively; 3) Confirm the peer device's optical module is working; 4) Check for fiber debris in the port and clean with fiber cleaning tools. Contact technical support if issue persists.

A: Methods: 1) Observe optical module indicator lights (usually LOS and PWR lights); 2) Login to device to check port status and optical power value (normal range: -8dBm to -25dBm); 3) Check for optical power alarms. Both low and high optical power can cause link instability.

A: DAC (Direct Attach Copper) is a pre-terminated copper cable with high-speed connectors on both ends for short-distance high-speed interconnect. Applications: 1) Server-to-switch connections (usually within 5m); 2) Spine-Leaf switch interconnect; 3) GPU server interconnect. Compared to optical module + fiber solution, DAC has lower cost and lower latency.

A: Passive DAC: contains no electronic components, pure copper transmission, suitable for within 7m, cost-sensitive scenarios. Active DAC: built-in signal amplification chips, can support longer distances (within 15m) and higher speeds (such as 112G PAM4). Selection depends on transmission distance and device compatibility.

A: Yes. According to specifications: 1) Passive DAC typically supports 0.5m-7m; 2) Active DAC can support up to 15m; 3) AOC (Active Optical Cable) can support longer distances. Exceeding recommended distance will cause signal attenuation and bit error rate increase.

A: Each has advantages: DAC has lower cost and lower latency but limited distance; AOC has longer distance (up to 100m) and lighter weight but slightly higher cost. Recommendation: prioritize DAC within 5m, choose active DAC or AOC for 5m-30m, choose optical module + fiber solution above 30m.

A: No. DAC/AOC is an integral cable, modules on both ends are paired and cannot be separated for use with optical modules or fiber patch cables. This differs from standalone optical modules. Note that both ends must have the same port type (e.g., QSFP+ to QSFP+).

A: Although DAC uses internal copper cables, excessive bending should still be avoided. General requirement: bending radius not less than 4 times the cable diameter. Excessive bending will cause signal attenuation and transmission errors. If布线 space is limited, consider AOC with smaller bending radius.

A: MPO (Multi-fiber Push On) is a multi-fiber fiber optic connector, commonly 12 or 24 fibers. MPO is mainly used in: 1) Data center high-density cabling; 2) 40G/100G/400G network aggregation links; 3) Pre-terminated fiber cabling systems. Compared to LC interface, MPO can greatly save patching space.

A: MPO-12 has 12 fibers, MPO-24 has 24 fibers. MPO-12 is commonly used for 40G/100G networks (such as QSFP+ optical modules); MPO-24 is commonly used for 400G networks (such as QSFP-DD optical modules). Selection depends on device port type.

A: Yes, MPO patch cables have Type A/B/C polarity: Type A (Straight-through): same key position on both ends, one-to-one correspondence; Type B (Reversed): key position on one end opposite to the other, 1-12 corresponds to 12-1; Type C (Pair-flipped): adjacent fibers crossed. Cabling system must have unified polarity rules, otherwise links will not work.

A: Based on transmission distance and application: 1) Multimode MPO (OM3/OM4 fiber, 850nm): lower cost, suitable for data center backbone links within 100m; 2) Singlemode MPO (OS2 fiber, 1310nm/1550nm): suitable for long distance (above 500m) or metro backbone. Prioritize multimode for short distance to save cost.

A: MPO patch cables usually connect to MPO-LC conversion cables or MPO panels: Device side uses MPO interface optical module (QSFP+ etc.) → MPO patch cable → MPO patch panel → LC patch cable → Device LC port. This method facilitates maintenance and flexible adjustments.

A: Use specialized MPO cleaning tools: 1) First use compressed air to blow away loose dust; 2) Wipe in one direction with MPO cleaning pen; 3) Visually inspect end face for stains or scratches. Protect immediately with dust cap after cleaning. Do not wipe directly with alcohol cotton, may leave fibers.
