Network adapters, also known as network interface cards (NICs), are hardware components that allow computers and other network devices to connect to a network. There are many different types of network adapters available, each with its own strengths and weaknesses. Here are some common types of network adapters and how they compare:
- Ethernet Network Adapters: Ethernet is the most common type of network adapter, used in both wired and wireless networks. Ethernet network adapters support data transfer rates of up to 100 Gbps and are compatible with a wide range of devices and networks. Ethernet adapters are relatively inexpensive and widely available, making them a popular choice for home and office networks.
- Fiber Optic Network Adapters: Fiber optic network adapters use fiber optic cables to transmit data and support higher data transfer rates than Ethernet adapters. They are commonly used in data centers and other high-performance environments that require fast and reliable network connectivity. Fiber optic network adapters can be more expensive than Ethernet adapters, but they offer greater speed and reliability.
- Wireless Network Adapters: Wireless network adapters allow devices to connect to a network without the need for cables. They use radio waves to transmit data and are commonly used in laptops, smartphones, and other mobile devices. Wireless network adapters are convenient and easy to use, but they can be susceptible to interference and can have slower data transfer rates than wired adapters.
- Bluetooth Adapters: Bluetooth adapters are used to connect devices wirelessly over short distances. They are commonly used in devices such as keyboards, mice, and headphones, but can also be used to connect computers and other devices to each other. Bluetooth adapters are relatively inexpensive and widely available, but have lower data transfer rates than other types of network adapters.
An SFP28 network adapter is a type of network interface card (NIC) that supports data transfer rates of up to 25 gigabits per second (Gbps). SFP28 stands for Small Form-factor Pluggable 28, which refers to the type of connector used to connect the adapter to a fiber optic cable.
SFP28 network adapters are commonly used in data centers and enterprise networks that require high-speed data transfer rates and low latency. They are designed to be used with fiber optic cables that use single-mode or multi-mode fiber, allowing for long-distance transmission of data.
One of the main advantages of SFP28 network adapters is their high data transfer rate. They are capable of transmitting data at speeds of up to 25 Gbps, which is significantly faster than earlier generations of network adapters.
SFP28 network adapters are also designed to be hot-swappable, which means they can be replaced without having to power down the server or network device. This makes it easier to perform upgrades or repairs without causing downtime.
Power EfficiencyThe HPE Ethernet 10/25GB 2-Port 622FLR-SFP28 Converged Network Adapter is designed to be power efficient, which can help reduce power consumption and lower energy costs. Here are some of the power efficiency features of this adapter:
- Energy Efficient Ethernet (EEE): The adapter supports EEE, which is a set of standards that helps reduce power consumption by automatically adjusting the power level of the network connection based on the amount of traffic being transmitted. This can help reduce power consumption during periods of low network activity.
- Wake-On-LAN (WOL): The adapter supports WOL, which is a feature that allows a computer to be turned on remotely over a network connection. This can help reduce the need to leave computers on all the time, which can help save energy.
- Advanced Power Management (APM): The adapter supports APM, which is a set of features that help reduce power consumption by controlling the power usage of the adapter and the system it is connected to. APM can help reduce power consumption during periods of low system activity.
- Low Power Consumption: The adapter is designed to be power efficient and has a low power consumption compared to other network adapters with similar capabilities. This can help reduce energy costs and lower the environmental impact of the network infrastructure.

What is the Manufacturer/Brand Warranty?
In general, a manufacturer's warranty service/support is a written guarantee to the buyer of a product. Its terms assure the replacement or repair of the product, if necessary, within a specified period after the purchase (2-5 years depending on the brand/manufacturer). It is typically included in the price of the product. Products are brand new and sealed and the original manufacturer box is complete with the Manufacturer's genuine warranty. For most of the brand new/retail products that come with the manual and box, exceptions may apply (i.e., Cisco, Juniper Networks).
For the server parts (i.e., Dell, HPE) to get Full coverage of the warranty server must have a full 3- 5 years warranty. However, ALLHDD.COM will cover the warranty duration if any Manufacturer doesn't support the advertised warranty and there is no refund for those.
