Product Description
The Dell 7TCDN is a high-performance transceiver module engineered for demanding 40 Gigabit Ethernet applications. Its QSFP+ form factor allows for high port density in switches and routers, crucial for modern data center environments. This module operates at a wavelength of 850nm, which is standard for short-reach multi-mode fiber (MMF) deployments. It utilizes a duplex LC connector, the common interface for MMF transceivers, and is typically compliant with the 40GBase-SR4 standard, enabling high-speed parallel transmission over fiber optic cables. With a reach of up to 100 meters on OM3 or OM4 multi-mode fiber, the 7TCDN is ideal for interconnecting servers, storage devices, and network switches within a data center rack or across adjacent racks. Its hot-swappable design ensures ease of installation and maintenance without requiring network downtime. This transceiver is a key component for building scalable and high-bandwidth data center infrastructures.
