Questions & Answers

Ask a Question

Can OSFP ports use modules in QSFP-DD form factor, such as Dell Q56DD-400G-SR8?

OSFP and QSFP-DD are two completely different form factors, so QSFP-DD optical modules like Cisco QDD-400G-FR4-S, QDD-400G-SR8-S, QDD-400G-LR4-S or QDD-400G-DR4-S all these optical transceivers cannot be used in OSFP ports.

Can a 400G link with one end using a Dell Q56DD-400G-SR8 optical module and the other end using Arista OSFP-400G-FR4 OSFP be interconnected?

Yes, OSFP and QSFP-DD are just physical form factors for modules, and as long as the modules are of the same type (such as both being 400G-DR4 or 400G-FR4), OSFP(Arista OSFP-400G-FR4) and QSFP-DD(Dell Q56DD-400G-SR8) modules can be interconnected.

Can the Dell Q56DD-400G-SR8 modules be used on QSFP-DD ports?

Yes, Dell Q56DD-400G-SR8 modules can be directly used on QSFP-DD ports, but it is important to configure the port speed appropriately when using them.

What is the maximum power consumption of a 400G module?

The maximum power consumption of the 400G modules provided by NADDOD is 14W (QDD-400G-ER8), and there are also low-power ER4（QDD-400G-ER4 lite）modules available for distances up to 40KM, with a power consumption of 12W.

What is the modulation mode of QSFP-DD 400G SR8 transceivers?

QDD-400G-SR8 transceiver adopts 8x50Gb/s PAM-4 modulation, "S" is the abbreviation of short, which means short distance transmission, and "8" means there are 8 optical channels.

What is the difference between QDD-400G-SR8 and OSFP-400G-SR8?

The main difference is the package, QDD-400G-SR8 is the QSFP-DD form factor and OSFP-400G-SR8 is the OSFP form factor. OSFP: OSFP stands for "Octal Small Form Factor Pluggable", the electrical interface of the OSFP connector consists of 8 electrical channels with 50Gb/s each, for a total bandwidth of 400Gb/s. QSFP-DD: QSFP-DD stands for "Quad Small Form Factor Pluggable (QSFP) - Dual Density (DD)". OSFP: OSFP stands for "Octal Small Form Factor Pluggable" and the electrical interface of the OSFP connector consists of eight electrical channels, each with 50Gb/s, for a total bandwidth of 400Gb/s. QSFP-DD: QSFP-DD stands for "Quad Small Form Factor Pluggable (QSFP) - Dual Density (DD)". The electrical interface of the QSFP-DD connector has eight electrical channels running at 50Gb/s per channel for a total bandwidth of 400Gb/s. The QSFP-DD form factor is similar to the QSFP form factor except that a second row of electrical contacts has been added to increase the number of high-speed contacts, and the electrical channels have been increased from four (in the QSFP) to eight (in the QSFP-DD).

What is the max transmission distance of the QDD-400G-SR8 transceiver?

When matched with OM3 multimode fiber, the farthest transmission distance is 70m; with OM4 multimode fiber, the farthest transmission distance can reach 100m.

What are the connection options for the 400G QSFP-DD SR8 transceiver?

Direct cable, using the same module at both ends, can realize 400G transmission; Breakout cable, using a 400G optical module at one end and eight 50G SFP56 optical modules at the other end, with MPO/MTP-16 to 8xLC multimode patch cables, to realize 400G to eight 50G connection.

Can QSFP-DD 400G transceiver be used directly in OSFP ports?

No. QSFP-DD and OSFP are two different form factors with different physical dimensions. OSFP is slightly larger than QSFP-DD and cannot be directly adapted.

Can I interconnect a QSFP-DD 400G SR8 module at one end and an OSFP 400G SR8 module at the other?

Yes, QSFP-DD and OSFP only describe the physical form factor of the module. Both modules are 8x50Gb/s modulated and can be interconnected using multimode MPO/MTP 16 APC patch cords.
