Description
Cable Length and Distance Support
The QSFP-H40G-AOC2M Cisco 2M 40G Direct-Attach Copper Cable is a high-speed cable designed for use in high-performance computing and networking environments. The cable has a length of 2 meters (6.56 feet) and supports distances of up to 2 meters.
This type of cable uses a direct-attach copper (DAC) design, which provides a low-cost and low-power solution for high-speed data transmission over short distances. The cable 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.
The QSFP-H40G-AOC2M cable is ideal for use in data center environments where high-speed connectivity is essential over short distances. Its short length and direct-attach design make it a cost-effective solution for connecting devices in close proximity, such as within a rack or cabinet.
Fiber Type and Connector Type
The QSFP-H40G-AOC2M is not a 2M 40G Direct-Attach Copper Cable. It is actually a 2-meter 40GBASE active optical cable (AOC) designed for use in data center and high-performance computing environments.
Regarding the fiber type and connector type used in this cable, they are as follows:
- Fiber Type: The cable uses multi-mode fiber (MMF) which is a type of optical fiber with a relatively large core diameter that allows multiple modes of light to propagate. MMF is commonly used for short-range optical communication applications such as data center interconnects.
- Connector Type: The cable uses QSFP (Quad Small Form-factor Pluggable) connectors which are a type of hot-swappable transceiver that plugs into the QSFP port of a network switch or router. The QSFP connector has four channels, each capable of transmitting at a rate of up to 10 Gbps, for a total bandwidth of 40 Gbps. The QSFP connector also has a locking mechanism to ensure a secure connection.
Network Topologies Supported
The QSFP-H40G-AOC2M Cisco 2M 40G Direct-Attach Copper Cable is a high-speed cable designed for use in high-performance computing and networking environments. The cable is compatible with a variety of network topologies, including:
- Point-to-Point (P2P) Topology: This is the simplest network topology that involves connecting two devices directly using the QSFP+ connectors on each end of the cable. The QSFP-H40G-AOC2M cable is ideal for this topology as it provides a direct-attach solution for high-speed data transmission over short distances.
- Switched Fabric Topology: This topology involves connecting multiple devices to a central switch that manages the flow of data between them. The QSFP-H40G-AOC2M cable can be used to connect devices to a switch with QSFP+ ports, providing high-speed connectivity within the switched fabric.
- Leaf-Spine Topology: This topology involves connecting multiple leaf switches to a spine switch, forming a hierarchical network architecture. The QSFP-H40G-AOC2M cable can be used to connect devices to the leaf switches, providing high-speed connectivity within the leaf-spine network.
- Mesh Topology: This topology involves connecting multiple devices to each other in a mesh-like structure, allowing for multiple paths for data transmission. The QSFP-H40G-AOC2M cable can be used to connect devices in a mesh topology, providing high-speed connectivity between devices.
