Product Description

Product Description

Precision Zinc Alloy Die Casting QSFP-DD 400G 800G Optical Transceiver Housing

Professional Introduction:

This high-precision die-cast housing is specifically designed for QSFP-DD (Quad Small Form-factor Pluggable – Double Density) optical transceivers. Engineered to meet the rigorous demands of next-generation data centers, it supports eight-lane interfaces for 400G and emerging 800G bandwidth scaling.

Technical Advantages:

Our precision die-casting process ensures ultra-thin wall thickness stability and complex internal geometries required for high-density components. The design provides exceptional EMI/RFI shielding effectiveness, critical for high-frequency signal integrity. High dimensional stability and excellent thermal conductivity are maintained to prevent heat throttling in dense networking environments.

Material Characteristics:

Manufactured using premium Zinc Alloy (Zamak 3 or Zamak 5) or high-grade Aluminum ADC12. These materials are selected for their superior flow characteristics during casting, allowing for high-detail reproduction and robust structural integrity.

Quality Control:

Components undergo rigorous 100% CMM dimensional inspection, salt spray testing for surface finish durability, and fit-form-function verification according to Multi-Source Agreement (MSA) standards. Our facility is ISO 9001:2015 and IATF 16949 certified.

Packaging & Export Info:

Products are packed in customized ESD-safe trays and vacuum-sealed moisture-barrier bags. Standard export sea-worthy/air-worthy cartons are used to ensure damage-free transit for international B2B procurement.

"Designed and manufactured by specialists with 10+ years of expertise in high-precision die casting for industry leaders."
