Can QSFPDD 400G XDR4 be compatible with QSFP56 or QSFP28 ports?

No, QSFPDD ports can use QSFP56 or QSFP28 optical modules, but QSFPDD optical modules cannot be used on QSFP56/QSFP28 ports.

Does QSFPDD 400G XDR4 support breakout?

QSFPDD 400G XDR4 is an MPO interface, as long as the device port using the module supports the breakout function, then 400G XDR4 can be paired with MPO to LC harness fiber to interconnect with the 100G FR module. This scenario is very common in the connection of 400G QDD switches to 100G QSFP28 switches.

Description

Juniper QDD-4X100G-FR-S Compatible 400G QSFP-DD XDR4 PAM4 LWDM4 Optical Transceiver Module (MUX/DEMUX design SMF MTP/MPO-12 2km DDM with FEC)

The Juniper 400G QSFP-DD XDR4 Module supports 100G breakout link lengths of up to 2km with FEC performed on the host platform. This 400GBase-DR4+ QSFP-DD transceiver has four pairs of single-mode fiber (SMF) with an MPO-12 connector. It's designed for 400 Gigabit Ethernet (GbE) and can be used as 4x100G breakout to QSFP28 100G-DR (up to 500m), 100G-FR, and 100G-LR. NADDOD offers Arista 400GBASE-XDR4 Compatible 400G QSFP-DD XDR4 (DR4+) Optical module, which adopts a 1310nm EML transmitter type and PAM4 pulse amplitude modulation mode, using a nominal wavelength of 1310 nm for 400Gb/s optical transmission. It is compliant to the IEEE 802.3cu for 100GBASE- FR1, and 400GAUI-8/CEI-56G-VSR-PAM4 standards. It is widely used in high-performance computing (HPC) networks, data centers, 400G Ethernet interconnect, enterprise core, and distribution layers, and service provider applications.

Questions & Answers

Ask a Question

Can OSFP ports use modules in QSFP-DD form factor, such as QDD-400G-XDR4?

OSFP and QSFP-DD are two completely different form factors, so QSFP-DD optical modules like QDD-400G-FR4, QDD-400G-SR8, QDD-400G-LR4 or QDD-400G-XDR4 all these optical transceivers cannot be used in OSFP ports.

The standard of QSFP56-DD is 8*50G, why are there only four channels in QSFPDD 400G XDR4?

The optical module mainly completes the optical-electrical conversion work, for the number of its signal channels, there are two dimensions: an electrical signal (i.e., host side, connected to the device) and an optical signal (i.e., optical path side, connected to the optical fiber), the 8*50G is its electrical signal channel mode on the host side, and the DSP chip of the QDD-400G-XDR4 module with the gearbox function, which can convert the electrical signals of the 8X50G into the 4X100G optical signal.

Which application scenarios are QSFPDD 400G XDR4 generally used in?

The QDD-400G-XDR4 transceiver is usually used to interconnect a 400G leaf switch with a spine, or a 400G QDD switch with a 100G QSFP28 switch, and as server NICs increase in speed, it can also be used to interconnect a 400G QDD switch with a 400G OSFP/QSFP112 NIC.

We were looking for long range transceiver modules for our NVIDIA SN4700 series switches and needed ones with MTP interfaces as we didn't want to replace the patch cables we already had, and the salesman recommended this 400G-XDR4, which is a great fit.
