Specifications

       Description:
  • The Dell QSFP-40G-SM4 77KC3 is a high-performance 40 Gigabit QSFP+ optical transceiver designed to deliver ultra-fast network connectivity in data center and enterprise networking environments. Utilizing shortwave wavelength division multiplexing (SWDM) technology at an 850nm wavelength, this module efficiently transmits data over two parallel multimode fibers (MMF), supporting distances of up to 300 meters.
  • With its robust construction and compact QSFP+ form factor, the QSFP-40G-SM4 provides reliable short-reach connections ideal for high-density switch uplinks, server interconnects, and other bandwidth-intensive applications.
       Key Features:
  • High-Speed 40Gbps Transmission – Supports next-generation networking demands with a full 40 Gigabit per second throughput.
  • SWDM Technology – Efficiently transmits data over two parallel MMFs using shortwave wavelength division multiplexing.
  • Short-Reach Capability – Optimized for up to 300 meters over multimode fiber, perfect for data center environments.
  • Duplex LC Fiber Connector – Industry-standard interface for easy integration with existing fiber infrastructure.
  • Compact QSFP+ Form Factor – Saves rack space and supports high-density deployments.
  • Compatible with Dell Network Equipment – Seamless integration with Dell switches and servers.
       Specifications:
