Description

Arista QDD-400G-FR4 Compatible 400G QSFP-DD FR4 PAM4 8 LWDM Optical Transceiver Module ( CWDM/DWDM SMF LC 2km DDM with FEC)

Arista QDD-400G-FR4 Compatible QDD FR4 is an advanced 400 Gigabit Ethernet (IEEE 802.3bs) transceiver that uses Long Wavelength Division Multiplexing (LWDM8) to transmit data over SMF (single-mode fiber) at speeds up to 400 Gbps. It supports eight channels of 50G 400GAUI-8 PAM4 (Pulse-Amplitude Modulation) over distances of up to 2 km using four wavelengths - 1271 nm, 1291 nm, 1311 nm, and 1331 nm. Additionally, the QDD FR4 supports Forward Error Correction (FEC) to help ensure reliable data transmission.

Questions & Answers

Ask a Question

Can OSFP ports use modules in QSFP-DD form factor, such as Cisco QDD-400G-FR4-S?

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 Arista QDD-400G-FR4 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(Arista QDD-400G-FR4) modules can be interconnected.

Can the Arista QDD-400G-FR4 modules be used on QSFP-DD ports?

Yes, Arista QDD-400G-FR4 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 main difference between SFPDD 400G FR4 and DR4?

There are two main differences: First, the optical interface is not the same, DR4 is an MPO interface, while FR4 is a duplex LC interface, in the same transmission distance under the use of FR4 is more saving fiber resources. Second, the transmission distance is not the same, FR4 has a higher sensitivity detector, the theoretical transmission is 2km, while the DR4 is only 500 meters.

What application scenarios of SFPDD 400G FR4 are typically used?

QDD-400G-FR4 is mainly used to interconnect the 400G QSFPDD spine switch with the spine or super spine. If the cluster scale is relatively large, the QDD-400G-FR4 may also be used to interconnect the leaf to the spine.

What kind of patch cables do I need to use with SFPDD 400G FR4?

QDD-400G-FR4 is a duplex LC interface, it can be used with regular single-mode fiber with LC connector.

Can it be used on a 200G QSFPDD port?

No. The 200G QSFPDD port is in 8X25G mode and does not support PAM4, and the FR4 module can't actively downscale to 8X50G.

What is the difference between SFPDD 400G FR4 and 400G-2XFR4?

First of all, the interface difference, QDD-400G-FR4 is a duplex LC interface, while 400G-2XFR4 is a 2XCS interface, which leads to a greater difference in their choice of fiber matching; Secondly, QDD-400G-FR4 optical path is 4X100G, while 400G-2XFR4 is 8X50G, which makes them have a certain difference in cost.
