Empowering next-generation data centers with superior performance, efficiency, and bandwidth — from UNIVISO TECHNOLOGIES & DEVELOP LIMITED.
The 400G QSFP-DD (Quad Small Form-factor Pluggable Double Density) optical module is designed to meet the growing demand for high-speed connectivity in modern data centers and cloud computing infrastructures. It supports 400Gbps data transmission over a compact form factor, offering twice the density of traditional QSFP modules.
High Bandwidth: Supports 400Gbps transmission rate with reliable signal integrity.
Compact Design: Double-density QSFP form factor allows for higher port density and scalability.
Low Power Consumption: Optimized power efficiency for energy-saving data centers.
Compatibility: Compliant with IEEE 802.3bs and QSFP-DD MSA standards.
Versatile Reach: Available in SR8, DR4, FR4, and LR4 variants for distances up to 10km.
400G modules are the backbone of next-generation data transmission systems. They are widely used in:
Data center interconnect (DCI) and high-performance computing (HPC)
5G core network backhaul and cloud infrastructure
AI training clusters and hyperscale cloud environments
