QSFP-H40G-CU1M - Cisco QSFP+ Module Direct Attach Cable Overview
QSFP-H40G-CU1M - Cisco QSFP+ Module Direct Attach Cable is a genuine modular capacity expansion product from Cisco, a global name in networking whose platforms are used by enterprises, service providers and data-center operators alike. Belonging to the Cisco family, the QSFP-H40G-CU1M unit is built to the original factory specification, so it integrates with existing Cisco deployments predictably and behaves exactly as the platform documentation describes. In the network, it is installed into a compatible chassis slot, where it works alongside the supervisor and line cards to extend the platform’s capabilities.
This unit follows the original factory specification for the Cisco family, covering its intended role without compatibility surprises. Standard mounting, cabling and management practices apply, and it interoperates with surrounding hardware using the same procedures as other Cisco equipment already deployed in the network.
Typical deployments include structured cabling for campus and data-center wiring, structured cabling for campus and data-center wiring, and structured cabling for campus and data-center wiring. Organizations commonly source it for refresh programs, capacity expansion and spares management, keeping a tested unit on hand so outages stay short and replacements are predictable. The factory detail for this unit reads: “Cisco 40GBASE-CR4 QSFP direct-attach copper cable, 1-meter, passive”. This makes it a practical choice when original-spec hardware is required at a predictable cost.
