HPE Aruba Instant On switches are the first choice for small and medium-sized businesses. Whether you want to wire a small office, connect racks or provide uplinks to core switches: there is a suitable TitanLink optic for every task: from SFP or SFP+ variations, to DACs and AOCs.

In many data centers, short fiber optic connections discreetly transport large amounts of data between switches, servers, and storage systems. At the heart of these connections is the 40G QSFP SR4 multimode transceiver, which allows data centers to upgrade to 40G without affecting their existing multimode fiber optic connections.

In most 100G networks, data traffic is handled by QSFP28 modules. They usually function flawlessly, but failures can occur. The signs are clear: a port that is not lit, increasing error counters, or a connection that drops under load. A step-by-step troubleshooting process will help you quickly and efficiently identify the cause.

100G QSFP28 modules transfer data between racks and across different rooms. Both SR4 and LR4 modules transmit 100 Gbps and fit into the same QSFP28 port. When setting up new connections or upgrading existing ones, you need to know which module is best suited for which application and how they differ in their data transfer capabilities.

A small business network needs to be reliable, have a simple infrastructure, be easy to manage, and have devices that work without any additional hassle. The HPE Aruba Networking 1900 Switch series is designed to do just that. This article explains which transceivers are compatible with the HPE Aruba 1900.

With increasing data traffic, 100G has become a practical step for aggregation and core connections, especially in data centers. The module that enables this change is the QSFP28 transceiver, which can provide 100G in an energy-efficient manner.

As networks transitioned from 10G and 40G to 100G, hardware developers had to introduce new optical modules to handle the load. Two of the most important product families that emerged were CFP and QSFP28. Both can handle 100G Ethernet, but were developed with different priorities and ultimately served different market segments.

Today, 800G is no longer just a concept—it's becoming a reality, and vendors are already testing speeds of 1.6 terabits. It's changing the way facilities are designed, equipment is cooled, and even the number of cables a technician needs to run in a busy rack. Read here what 800G-Networks mean.

Instead of copper conductors transmitting the signal to DACs, the electrical data from the switch or network card is converted into light in the AOC's transceiver head. A 10G SFP+ AOC is designed for standard 10 Gigabit Ethernet speeds of 10.3125 Gbps. 10G SFP+ AOCs are used for short to medium-length connections without the limitations ... 

Shutting down devices to replace a module in data centers and carrier networks is rarely possible. Their hot-pluggability allows you to unplug and plug in a transceiver while the switch remains online, maintaining data traffic. In this article, we will help you reliably use hot-pluggable transceivers.

Ethernet has long since left behind the days when 1G or 10G connections were sufficient. However, switching directly to 40G or 100G can be expensive and power-hungry. 25G Ethernet offers the ideal solution, especially the 25G SFP28 LR singlemode transceiver for stable, long-range connections, the special features of which we will outline in this article.

From a distance, the modules in the ports of switches and servers appear similar for network modules. However, the form factor names reveal a lot about the different types of connections they enable. Understanding the differences makes network planning or upgrading older equipment easier.
