FAQ for 400G QSFP-DD Optical Transceiver Module

Q1:What is QSFP-DD-400G-DR4? A:The 400G QSFP-DD DR4 is a hot pluggable optical transceiver module with a speed of 400Gbps, a wavelength of  1310nm, and a transmission distance of up to 500m with MPO-12,OS2 SMF. It is ideal for data centre, 400G Ethernet and Infiniband Interconnects.

Q2:What is the maximum transmission distance of the 400G QSFP-DD DR4 transceiver?A:HYTOPTODEVICE QSFP-DD 400G DR4 module supports the maxium transmitting distance of up to 500m with MPO-12, OS2 SMF

Q3:What fiber connector is required for the HYTOPTODEVICE QSFP-DD-400G-DR4?A:The 400G QSFP DD DR4 module uses an MPO-12 connector with SMF.

Q4:Does the HYTOPTODEVICE QDD-400G-DR4-S 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 QSFP-DD-400G-DR4 support breakout to 100G?A:Yes, The 400G DR4 module operates by using 4 independent channels, each channel running at 100G PAM4. so the HYTOPTODEVICE QSFP-DD-400G-DR4 transceiver fully supports breakout applications to 4x 100G. You can use the QSFP-DD 400G DR4 to break out to 4 x 100G-DR  transceivers (such as Cisco QSFP-100G-DR-S) using an MPO-12 to 4xLC Duplex(UPC) SMF breakout cable.

Q6:Where to buy 400G QSFP DD DR4 optical transceiver?A:There are many factories that produce and sell 400G  fiber optic transceivers, 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:Q: Why choose the HYTOPTODEVICE QSFP-DD-400G-DR4 over the DR8 version? A: The QSFP-DD-400G-DR4 version is designed for improved efficiency. It uses an MPO-12 connector (100G standard), while the QSFP-DD-400G-DR8 requires an MPO-16 connector. If you already have MPO-12 fiber installed, the HYTOPTODEVICE 400G DR4 is a more economical option.This will allow you to upgrade from 100G to 400G using the existing MPO-12 cabling.

Q8:Is the 400G QSFP-DD DR4 backward compatible with lower-speed modules,such as 100G?A: Yes. QSFP-DD 400G DR4 uses parallel fiber (MPO-12). Using an MPO-to-4xLC breakout cable, you can link it to four 100G-DR (PAM4) transceivers.

 Q9:How do HYTOPTODEVICE ensure 400G QSFP-DD DR4 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 QDD-400G-DR4 hot-swappable?A:HYTOPTODEVICE fiber transceiver modules are hot-pluggable, hot Pluggable QSFP-DD MSA Compliant.you can plug or unplug the optical transceiver, while the device is powered on without damaging the hardware.

Q11:who makes the best 400g transceiver?A: 400G Optical Transceiver Manufacturer China HYTOPTODEVICE ensures that the QDD-400G-DR4 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.Power efficiency, thermal management, multi-vendor compatibility,fast delivery are HYTOPTODEVICE advantage and commitment.

Q12：Does it use MPO-12 or MPO-16？A:The 400G QSFP-DD DR4 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.
