FAQ for Nvidia 400G Transceiver MMA1Z00-NS400  QSFP112 Fiber Module

Q1:What is Q112-400G-SR4? A:The 400G QSFP112 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 MPO-12,OM4 MMF. It is ideal for data centre, 400G Ethernet and Infiniband Interconnects.

Q2:What is the maximum transmission distance of the 400G QSFP112 SR4 transceiver?A:HYTOPTODEVICE QSFP112 400G SR4 module supports the maxium transmitting distance of up to 100m with MPO-12, OM4 MMF

Q3:What fiber connector is required for the HYTOPTODEVICE QSFP112-400G-SR4?A:The 400G QSFP112 SR4 module uses an MPO-12 connector with MMF.

Q4:Does the HYTOPTODEVICE QSFP112-400G-SR4 require FEC?A:Yes. According to the IEEE 802.3db standard, Host KP4 FEC must be enabled on the Cisco switch port to achieve the 100m distance with a reliable Bit Error Rate (BER).

Q5:Does the HYTOPTODEVICE QSFP112-400G-SR4 support breakout to 100G?A:No.the Q112-400G-SR4 uses 4x100G PAM4,Standard 100G-SR4 uses 4x25G NRZ modulation. their modulation is different.Unless the 100G SR use the  100G-SR1 (PAM4) modules, and the switch must support the appropriate Gearbox/FEC settings in EOS.

Q6:Where to buy 400G QSFP112 SR4 optical transceiver?A:There are many factories that produce and sell 400G  fiber optical modules, but 400G optical transceiver manufacturer china HYTOPTODEVICE is the excellent provider: 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 QSFP112 SR4 backward compatible with lower-speed modules,such as 100G?A: Yes. QSFP112 400G SR4 uses parallel fiber (MPO-12). Using an MPO-to-4xLC breakout cable, you can link it to four 100G-SR (PAM4) transceivers.

 Q9:How do HYTOPTODEVICE ensure 400G QSFP112 SR4 module compatibility with network switch?A:Ensuring 100% compatibility, optical transceiver modules must be coded to match the switch's requirements. 400G Optical Transceiver Manufacturer China HYTOPTODEVICE was equipped with various high-speed switch,the brands include such as Cisco,NVIDIA,Arista,Juniper. highly professional in coding equipment for various brands to ensure they are recognized and running in your  device.
 
Q10:Is Q112-400G-SR4 hot-swappable?A:HYTOPTODEVICE fiber transceiver modules are hot-pluggable, hot Pluggable QSFP112 MSA Compliant.you can plug or unplug the optical transceiver, while the device is powered on without damaging the hardware.

Q11:Why Choose HYTOPTODEVICE for  QSFP112-400G-SR4?A: High-Speed Optical Transceiver Manufacturer China HYTOPTODEVICE ensures that the Q112-400G-SR4 is coded and tested for full compatibility with major switch vendors (such as Cisco, Juniper, Arista, and huawei). They verify the EEPROM settings to ensure "plug-and-play" functionality without port-recognition errors.

Q12：Does it use MPO-12 or MPO-16？A:The 400G QSFP-DD SR4 uses MPO-12 connector. There are 4 transmit and 4 receive channels (8 fibers total). An MPO-12 connector is used, with the 4 middle fibers typically remaining unused.
