Custom Die Cast Aluminum QSFP/QSFP-DD/OSFP/CFP Optical Module Housing | 400G/800G Transceiver Shell Manufacturer

1.Product Overview
Our aluminum die cast optical module housings are precision engineered for mainstream high-speed optical transceivers including QSFP+,QSFP28,QSFP-DD,OSFP,CFP/CFP2/CFP4 series, covering 40G/100G/400G/800G data transmission specifications.
Two mainstream structural designs: finned heat dissipation type and fully enclosed sealed type, matched with detachable plastic pull tab for convenient plug & pull from switch slots.
Made of high-grade ADC12 aluminum via high-pressure die casting plus CNC precision machining, surface treatment options: nickel plating, passivation. All dimensions controlled within ±0.02mm tolerance to comply with international industry form factor standards.
2.Core Product Advantages
Dual structural options for different usage demands
Heat sink fin version: Integrated radial fin structure expands heat exchange area, rapidly dissipate heat generated by high-power chips, effectively avoid overheat throttling for 800G high-consumption modules, ideal for AI server & short-range data center interconnection.
Fully sealed closed version: Complete enclosed metal cavity with superior full-band EMI shielding performance, prevent internal signal leakage and external electromagnetic interference, perfect for long-distance telecom backbone transmission & industrial harsh environment.
Uniform plastic pull tab: Secure buckle design, durable after repeated plugging, easy module maintenance.
Excellent EMI & EMC Performance
Integrally formed aluminum shell without splicing gaps, effectively block EMI/RFI noise, stabilize high-speed digital signal transmission, fully meet international EMC standards for communication equipment.
Outstanding Heat Dissipation
Aluminum base features high thermal conductivity, finned design enhances natural convection cooling, guarantee stable 7×24-hour continuous operation of transceivers in data center racks.
High Precision Machining
Combination of die casting and CNC milling, precise positioning slot, optical port and buckle dimension, smooth plug-in without stuck, universal fit for mainstream brand switches and router slots globally.
Good Corrosion Resistance
Optional chemical nickel plating or natural passivation finish, excellent salt spray & moisture resistance, applicable for indoor IDC room and outdoor base station cabinet scenarios.
