Hey there! As a supplier of 400G QSFP - DD DR4 products, I'm super stoked to dive deep into the technical specifications of these bad - boys. Let's get right into it!
First off, what the heck is a 400G QSFP - DD DR4? Well, it's a high - speed optical transceiver module that's designed to support 400 Gigabit Ethernet (400GbE) applications. It follows the QSFP - DD (Quad Small Form - factor Pluggable Double - Density) standard, which is a hot technology in the data center and high - speed networking game.
Physical and Mechanical Specs
The 400G QSFP - DD DR4 has a sleek and compact design. It's about the size you'd expect for a modern, high - density transceiver. The form factor is crucial because it allows for a high port density in network switches and routers. This means more data can be transmitted and received in a smaller space, which is a huge plus for data centers where space is at a premium.
The module has a standard QSFP - DD connector interface. This interface is well - established and widely used, so it's easy to integrate into existing network infrastructure. It also supports hot - plugging, which means you can insert or remove the module while the system is running without causing any disruptions. That's super convenient for maintenance and upgrades.
Electrical Specs
In terms of electrical performance, the 400G QSFP - DD DR4 operates at a high speed. It can achieve a total data rate of 400 Gbps, which is mind - bogglingly fast. This high data rate is achieved through a combination of four lanes, each operating at 100 Gbps.
The module has low power consumption. In today's energy - conscious world, this is a big deal. Low power consumption not only saves on electricity bills but also reduces the heat generated by the module. Less heat means better reliability and a longer lifespan for the transceiver.
It also has excellent signal integrity. The electrical design of the 400G QSFP - DD DR4 ensures that the transmitted signals are accurate and free from interference. This is crucial for maintaining high - quality data transmission over long distances.
Optical Specs
Optically, the 400G QSFP - DD DR4 uses a Direct Attach Copper (DAC) or a fiber - optic connection. When using fiber - optic cables, it typically operates at a wavelength of around 850 nm. This wavelength is well - suited for short - reach applications, such as within a data center.
The module has a high optical output power. This means it can transmit signals over relatively long distances without significant signal degradation. It also has a high sensitivity, which allows it to receive weak signals effectively.

Protocol Compatibility
The 400G QSFP - DD DR4 is compatible with a variety of networking protocols. It supports 400 Gigabit Ethernet, which is the standard for high - speed data center networks. It also works with other emerging protocols, which makes it a versatile choice for future - proofing your network.
Comparison with Other Modules
Now, let's compare the 400G QSFP - DD DR4 with some other similar modules, like the 400G OSFP DR4+. The OSFP (Octal Small Form - factor Pluggable) module is another option for 400G networking. While the 400G OSFP DR4+ also offers high - speed data transmission, the QSFP - DD DR4 has a more compact form factor. This can be a deciding factor for data centers that need to maximize port density.
The OSFP Optical Module is also a great alternative. However, the QSFP - DD DR4 is often more cost - effective, especially for large - scale deployments.
Applications
The 400G QSFP - DD DR4 is perfect for a wide range of applications. In data centers, it can be used for server - to - switch and switch - to - switch connections. It can handle the massive amounts of data traffic generated by modern cloud computing, big data analytics, and artificial intelligence applications.
It's also suitable for high - performance computing (HPC) environments. HPC systems require high - speed data transfer between nodes, and the 400G QSFP - DD DR4 can meet those demands.
