Cisco 40 Gigabit Adapter CVR-4SFP10G-QSFP

In the fast-moving world of enterprise networking and modern cloud data centers, IT leaders continually seek efficient ways to increase network bandwidth without expanding their physical footprint. Cisco addresses this challenge directly with advanced optical interconnect technology that provides standard-setting performance, scalability, and operational reliability. As bandwidth demands escalate across modern enterprise infrastructures, adopting high-density 100G optical solutions has become vital for maintaining smooth data transmission.

To meet these industry requirements, Cisco introduced its 100G SFP-DD (Small Form-Factor Pluggable Double Density) module family. This solution doubles the density of standard SFP interfaces by using a two-lane electrical channel within a small physical package. As a result, organizations can effectively double their port density and upgrade overall throughput without replacing existing switch racks or compromising efficiency.

Product overview

The Cisco 100G SFP-DD product line includes a comprehensive range of optical transceivers, direct-attach copper cables, and active optical cables built for high-density environments. By doubling connection density relative to traditional SFP28 and SFP56 form factors, this portfolio enables systems integrators to optimize front-panel real estate across high-performance routers and switches.

The optical transceiver series covers a wide variety of distance requirements and cable types. For short-distance connections, the Cisco SFPDD-100G-SR4 operates over multimode fiber up to 100 meters. Single-mode optical deployments are covered by the SFPDD-100G-DR-S for 500-meter reach, the SFPDD-100G-FR-S for distances up to 2 kilometers, and the SFPDD-100G-LR4 for long-reach links up to 10 kilometers. Furthermore, the SFPDD-100G-CWDM4 provides cost-efficient multiplexed transmission over 2 kilometers of single-mode fiber.

To support high-density short-range connections inside server racks, Cisco offers Direct Attach Copper (DAC) cables, including models SFPDD-PC0101, SFPDD-PC0151, SFPDD-PC0202, and SFPDD-PC0205. For flexible intra-rack and row-to-row setups, Cisco supplies Active Optical Cables (AOC) such as the SFPDD-100G-AOC1M, AOC2M, AOC3M, AOC5M, AOC7M, and AOC10M models, providing lightweight cabling alternatives.
