High Precision QSFP Optical Transceiver Zinc Alloy Housing | Custom Die Casting Shell
EMI Shielding Metal Enclosure for 40G/100G QSFP Fiber Optical Module
2026-06-21
Product Overview
This QSFP optical transceiver metal housing is a core structural component for high-speed fiber optic modules. Adopting premium Zamak zinc alloy material and high-pressure die casting process, this enclosure provides reliable mechanical protection, excellent electromagnetic interference shielding and outstanding thermal management for internal optical and electronic components. Reserved positioning posts and mounting holes ensure precise assembly with standard QSFP cages, perfectly adapting to high-density cabinet deployment scenarios of data centers.
Production Manufacturing Process
- High precision die casting with customized molds, dimensional tolerance controlled within ±0.02mm
- CNC precision secondary machining for positioning holes and interface structures
- Optional surface treatments: nickel plating, tin plating, passivation anti-corrosion treatment
- Deburring, polishing and full inspection of appearance and dimensions
- Strict assembly fit testing before factory delivery
Core Product Advantages
- Superior EMI Shielding: High-conductivity zinc alloy effectively isolates electromagnetic signal interference to guarantee stable high-speed data transmission
- Efficient Heat Dissipation: Optimized cavity structural design quickly dissipates operating heat and extends the service life of optical modules
- High Assembly Precision: Precisely reserved positioning holes and snap-fit structures ensure seamless matching with standard QSFP sockets
- Strong Mechanical Durability: Shock-resistant, wear-proof and anti-corrosion, adapting to long-term continuous operation in harsh IDC room environments
- Flexible Customization: Support structural modification, surface finish adjustment, laser brand logo engraving and personalized packaging
