High Precision QSFP56 QSFP-DD Optical Transceiver Zinc Alloy Housing

This QSFP-DD and QSFP56 series optical transceiver metal housing is specially developed for next-generation high-speed fiber communication modules. Adopting high-performance Zamak zinc alloy raw material and precision die casting forming process, this split metal shell provides reliable mechanical protection, efficient electromagnetic interference shielding and excellent heat dissipation guarantee for internal high-speed optical chips and circuit components.
Two structural designs are available: one with rear heat dissipation slotted structure and one with fixed mounting lug design, which can adapt to different heat dissipation and installation requirements of high-density server cabinets.
Manufacturing Technology
High precision customized mold die casting, dimensional tolerance strictly controlled within ±0.02mm
CNC precision secondary machining for mounting holes, positioning slots and interface structure
Optional surface treatment: nickel plating, bright tin plating, matte anti-corrosion passivation
Deburring, surface polishing, salt spray anti-rust treatment and full dimensional inspection
Assembly fit test and EMI shielding performance test before factory delivery
Core Product Advantages
Excellent EMI Shielding Performance: High conductivity zinc alloy effectively isolates high-frequency electromagnetic interference to ensure stable transmission of 200G/400G high-speed signals
Optimized Heat Dissipation Design: Optional rear slot heat dissipation structure accelerates air convection, quickly takes away the heat generated by high-power optical modules
Ultra-high Assembly Precision: Standard QSFP-DD dimensional design, seamless fit with official standard cages without assembly deviation
Strong Mechanical Stability: Integrated die-casting structure, shock-resistant, anti-deformation and durable for long-term continuous operation in IDC equipment rooms
Diversified Structural Selection: Two mainstream installation structures can be selected to meet different customer installation and heat dissipation scene demands
