FAQ for NVIDIA MMA4Z00-NS400 Compatible SFP+Transceivers

Q1:What is OSFP-400G-SR4? A:The 400G OSFP SR4 is a hot pluggable optical transceiver module with a speed of 400Gbps, a wavelength of 850nm, and a transmission distance of up to 100m with OM4 MMF. It is ideal for data centre, 400G Ethernet and Infiniband Interconnects.

Q2:What is the maximum transmission distance of the 400G OSFP SR4 transceiver?A:HYTOPTODEVICE OSFP 400G SR4 module supports the maxium transmitting distance of up to 50m with OM4 MMF.

Q3:How is the 400G OSFP SR4 compatibility with MMF fiber?A:The OSFP-400G-SR4 optical transceiver is fully compatible with MMF Fiber, it has a maximum transmission distance of up to 50 meters with OM4 MMF.

Q4:What is the 800G SR8 vs 400G SR4 transceiver comparison?A:Both the OSFP 800G SR8 and OSFP 400G SR4 are MMF optic modules with a wavelength of 850nm and a transmission distance up to 50m (OM4 MMF). The difference is that the 800G SR8 doubles the 800G speed by using eight 100Gbps channels, while the 400G SR4 has a speed of 400Gbps and uses four 100Gbps channels.

Q5:What are the power consumption and cooling requirements for the 400G SR4 modules?A:The power consumption of an 400G SRF optical transceiver is generally around 6-9W, depending on the specific model.adequate cooling is required to maintain the performance and lifespan of optical transceivers.

Q6:Where to buy 400G OSFP SR4 multimode optical transceiver?A:There are many manufacturers that produce and sell 400G fiber optical modules, but HYTOPTODEVICE is the excellent manufacturer: a source factory, fully controllable process, reliable performance, 100% compatible, sufficient inventory, fast delivery, and quick response.

Q7:The link is "Up" but I have high packet loss. Why? A:There could be two reasons,1. Dirty connectors:tiny dust particles can obstruct signal transmission. Please use fiber optic cleaner to clean the connector. 2. Fiber optic cable bending: avoid severe bending of the fiber optic cable.

Q8:Is the 400G SR8 backward compatible with lower-speed modules,such as 100G?A:Yes,The 400G SR4 is backward compatible with lower-speed optical transceivers, such as 200G,100G and 50G, but the performance will be reduced.

Q9:How do HYTOPTODEVICE ensure 400G OSFP SR4 module compatibility with network switch?A:Ensuring 100% compatibility, optical modules must be coded to match the switch's requirements. Source-factory HYTOPTODEVICE was equipped with various high-speed switch,the brands include such as Cisco,NVIDIA,Huawei. highly professional in coding equipment for various brands to ensure they are recognized and running in your device.

Q10:Is OSFP-400G-SR4 hot-swappable?A:HYTOPTODEVICE fiber transceiver modules are hot-pluggable, hot Pluggable OSFP MSA Compliant.you can plug or unplug the optical transceiver, while the device is powered on without damaging the hardware.

Q11:Why is the Flat Top (OSFP-RHS) design necessary?A: The 400G OSFP SR4 use the Flat Top OSFP design for optimized thermal management, it is very important for adapter cards (like ConnectX-7), that use the riding heat sink on the connector cage for cooling, so that the pluggable transceiver stays within the 0°C to 70°C (32 to 158°F) operating temperature range.
