High-Speed Data Transmission

The Cisco QSFP-H40G-AOC-25M= 25 Meter 40GB Base Active Optical Cable is designed to provide high-speed data transmission between devices. The cable uses Active Optical Cable (AOC) technology, which combines the speed and low-latency of optical fiber with the flexibility and ease of use of copper cabling.

With a maximum data transfer rate of 40 Gbps, the cable is ideal for high-bandwidth applications such as HPC and cloud computing. The cable uses multimode fiber (MMF) to transmit data over distances of up to 25 meters, making it suitable for use in medium-sized data centers.

The cable also features QSFP+ (Quad Small Form-factor Pluggable Plus) connectors on both ends, which are compatible with QSFP+ ports on devices such as switches, NICs, and routers. This makes it easy to connect the cable to a variety of devices and configure them for high-speed data transmission.

In addition, the cable has a low power consumption of less than 1 watt, which makes it energy-efficient and environmentally friendly.

Low Power Consumption

Cisco QSFP-H40G-AOC-25M is a 25-meter 40GBASE active optical cable designed for use in data center and high-performance computing environments. Compared to traditional copper cables, active optical cables are known for their low power consumption.

Here are some of the key features of Cisco QSFP-H40G-AOC-25M that contribute to its low power consumption:

  • Optical technology: The cable uses optical technology to transmit data, which requires less power than copper-based cables. In addition, optical cables do not generate electromagnetic interference (EMI), which reduces the need for power-consuming shielding.
  • Active electronics: The cable has active electronics that help to boost the signal and extend the reach of the cable. These electronics consume less power than traditional copper-based cables.
  • Low power consumption transceivers: QSFP transceivers used in the cable are designed to consume less power than traditional copper-based transceivers. This reduces the overall power consumption of the cable.
  • Energy Efficient Ethernet (EEE): The cable supports Energy Efficient Ethernet (EEE) standard which helps in reducing the power consumption during idle periods.

Cisco QSFP-H40G-AOC-25M is designed to be a low power consumption solution for data center and high-performance computing environments, providing cost savings and reduced environmental impact.

Cable Specifications and Features

The Cisco QSFP-H40G-AOC-25M= 25 Meter 40GB Base Active Optical Cable is a high-performance cable designed for fast and reliable data transmission in high-performance computing and networking environments. Here are the specifications and features of the cable:


  • Length: 25 meters (82 feet)
  • Data Transfer Rate: 40 Gbps
  • Connector Type: QSFP+ (Quad Small Form-factor Pluggable Plus) on both ends
  • Fiber Type: Multimode fiber (MMF)

About New Bulk Pack Products

New Bulk Pack products come with clamshell boxes and do not have any manufacturer warranty. Many times manufacturers disassemble whole units to use parts or pulled from a new system. Typically, this product doesn't come with software or instructions unless indicated and no Manufacturer’s genuine warranty. You can take note these are not brand new products.

Cables - Optical Cable

Many people are currently talking about fiber optic cables. This new invention is the future of computer networking, taking over from all-time copper wire cables. If you are looking forward to setting up a new data center, or you just want an upgrade, then optical fiber cable is the way to go. It might seem like a new invention, but the cables are all out there. You can get any networking cable and interfacing cable you need for your application.

Types of Fiber Optical Cables for Networking

We may not exploit all the types of these optical cables out there, but we must bring it to your attention that you will always get what you need. There are two major categories of these cables depending on the core material. We have either plastic or glass cables, but these should not make any difference if you just want a home or office networking.

The two major categories are broken down into small groups of interest depending on the end connectors. The list of subgroups is endless, but we will quickly mention the commonly used ones. On the list, we have LC-LC cable, InfiniBand, ProLiant, Patch cable, and standard fiber optical cables. Please note that the first three items on the list are special-purpose cables commonly used in data centers.

Get Greater Bandwidth with Optical Cable

Fiber optical cable or LC cable was invented to replace copper cables because of their limited bandwidth. As technology advances, there is a need for a higher data rate than copper wires can handle. Fiber optic cable has more bandwidth compared to copper conductors of the same diameter. It never matters whether you have single-mode or multimode fiber cables; your applications are always at the top.

Higher Data Transfer Rates

Fiber optical cables are also champions when it comes to data speeds. Unlike copper conductors that rely on electrons to transfer data, fiber cables use light. So, the theoretical data rate is the speed of light. It can deliver data at that high speed while maintaining integrity. The resistance of fiber cables to environmental and magnetic interference with the signal is also remarkable!

Cheaper in the Long Run

What turns people away from fiber cables is the initial purchase price, but that is predicted to fall in the coming years. Despite that, these cables are very much cheaper in the end because of almost no maintenance cost. They also come with many advantages over their distant rivals, copper cables, worth the cost. What you actually pay for when you buy an optical cable is the performance and technology used in the manufacturing.

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.
