About This Part
The Dell Part Number 0H93DH represents a high-performance QSFP+ (Quad Small Form-factor Pluggable Plus) optical transceiver, specifically designed for 40 Gigabit Ethernet applications. This module, manufactured by Dell, is a critical component within modern data center and enterprise network infrastructures, facilitating high-speed optical data transmission. Adhering to the 40GBASE-LR4 standard, it operates over four distinct wavelengths around 1310nm, multiplexed onto a single pair of single-mode fibers. Each lane transmits data at 10Gbps, aggregating to a total data rate of 40Gbps. The QSFP+ form factor ensures hot-pluggability and high port density, making it suitable for compact networking equipment. With a maximum reach of 10 kilometers over standard single-mode fiber (SMF), the Dell 0H93DH is ideal for medium-distance optical links, offering robust and reliable connectivity for demanding network environments. Its technical specifications ensure interoperability with other 40GBASE-LR4 compliant equipment, providing a versatile solution for high-bandwidth requirements. This Dell QSFP+ transceiver is primarily deployed in scenarios demanding high-bandwidth, medium-distance optical connectivity. Typical use cases include inter-rack aggregation within large data centers, connecting core switches to distribution layers, or establishing robust links between geographically separated data center facilities (Data Center Interconnect - DCI). Telecommunications operators utilize such modules for backhaul networks and metropolitan area networks, while cloud service providers rely on them for their massive server farms and network infrastructure. The Dell 0H93DH effectively solves the challenge of extending 40Gbps Ethernet links beyond the reach of copper cabling or shorter-range fiber optics, providing a cost-effective alternative to more complex and expensive DWDM solutions for specific distances. It serves as a crucial upgrade path for networks transitioning from 10Gbps to 40Gbps, enabling significant capacity enhancements without requiring a complete overhaul of the fiber plant, especially for existing single-mode fiber deployments.
