Hey there! As a supplier of 400G QSFP112 SR4, I often get asked about the differences between 400G QSFP112 SR4 and 400G OSFP SR4. So, I thought I'd write this blog to break it down for you.
Form Factor
First off, let's talk about the form factor. The 400G QSFP112 SR4 comes in a QSFP112 form factor. It's a bit more compact compared to the 400G OSFP SR4, which uses the OSFP (Octal Small Form-factor Pluggable) form factor. The OSFP is larger, and it's designed to handle more power and better cooling. This larger size can be a drawback in some setups where space is limited. But on the flip side, the extra space allows for better heat dissipation, which can be crucial for high - speed data transmission.
The QSFP112 form factor, on the other hand, is more widely used in existing network equipment. Many data centers already have infrastructure that's compatible with QSFP - based modules. So, if you're looking to upgrade your network to 400G and you want to use your existing hardware as much as possible, the 400G QSFP112 SR4 might be a better choice. It can fit into QSFP - compatible ports without any major modifications.
Power Consumption
Power consumption is another important factor. The 400G OSFP SR4 generally consumes more power than the 400G QSFP112 SR4. This is mainly due to its larger size and the additional components it has for better cooling and performance. Higher power consumption means higher electricity bills, which can be a significant concern for large - scale data centers.
The 400G QSFP112 SR4 is more power - efficient. It can help data centers save on energy costs, especially when you're deploying a large number of these modules. And with the increasing focus on energy efficiency in the tech industry, this can be a major selling point.
Transmission Distance
When it comes to transmission distance, both the 400G QSFP112 SR4 and 400G OSFP SR4 are designed for short - reach applications. They typically support transmission distances of up to 100 meters over multi - mode fiber. However, in some cases, the performance might vary slightly due to differences in the internal components and design.
In general, the difference in transmission distance between the two is not significant for most short - reach network setups. But if you're working in a situation where every meter counts, it's important to test both modules in your specific environment to see which one performs better.
Compatibility
Compatibility is a big deal. As I mentioned earlier, the 400G QSFP112 SR4 is more likely to be compatible with existing QSFP - based network equipment. This means you can easily integrate it into your current network without having to replace a lot of hardware.
The 400G OSFP SR4, being a relatively new form factor, might require some upgrades to your network infrastructure. You may need to replace network switches or other components to support the OSFP form factor. This can add to the overall cost of upgrading your network.
Cost
Cost is always a consideration. The 400G QSFP112 SR4 is usually more cost - effective. Since it's based on a more established form factor and has lower power consumption, the overall cost of ownership is often lower. You don't have to spend as much on hardware upgrades, and you'll save on energy costs in the long run.
The 400G OSFP SR4, with its larger size and more advanced features, tends to be more expensive. If you're on a tight budget, the 400G QSFP112 SR4 might be the way to go.
Applications
Both modules are suitable for high - speed data center applications. The 400G QSFP112 SR4 is great for intra - rack connections where space is limited and power efficiency is important. It can also be used in small to medium - sized data centers that want to upgrade to 400G without a major overhaul of their infrastructure.
The 400G OSFP SR4 is more suitable for large - scale data centers that can afford the higher cost and need the better cooling and performance that the larger form factor provides. It's also a good choice for future - proofing your network, as the OSFP form factor is expected to become more popular in the coming years.
Market Availability
In terms of market availability, the 400G QSFP112 SR4 is more readily available. There are more suppliers in the market, which means you have more options to choose from. This also leads to more competitive pricing.
The 400G OSFP SR4, being a newer technology, might have a more limited supply in some regions. You may have to wait longer to get your hands on it, and there might be fewer suppliers to choose from.

Conclusion
So, in conclusion, the choice between 400G QSFP112 SR4 and 400G OSFP SR4 depends on your specific needs. If you're looking for a compact, power - efficient, and cost - effective solution that's compatible with existing infrastructure, the 400G QSFP112 SR4 is a great choice. On the other hand, if you need better cooling, performance, and are willing to invest in infrastructure upgrades for future - proofing, the 400G OSFP SR4 might be the way to go.
