40g Qsfp Optical Transceiver Zinc Alloy Die-Cast Housing Kit with Pull Tab & EMI Shielding

Focusing on optical communication die-casting accessories for over 20 years, we specialize in high-precision zinc alloy die-cast SFP, QSFP and XFP module housings. Adopting professional hot-chamber high-pressure die-casting technology, our products feature tight tolerance, excellent EMI shielding, stable heat dissipation and ultra-long plug durability. Most products are exported to Europe, America, Southeast Asia and other global markets, fully compliant with international telecom equipment asse

We adopt full-process quality control from raw material incoming inspection, die-casting forming, CNC precision machining, surface electroplating to finished product packaging. Equipped with professional salt spray testers, coating thickness gauges and 2D dimensional testing equipment, all housings pass strict plug life test and anti-corrosion test, complying with RoHS, REACH and international telecom industry quality requirements.

Absolutely. We support full customized OEM/ODM solutions for optical module housings, including custom surface finishes (semi-bright / high-gloss / thick passivated nickel plating), pull tab colors, laser LOGO, internal cavity structure modification and latch tension adjustment. Our technical team optimizes products according to clients' equipment matching and market demand.

As a professional manufacturer focusing on communication die-casting parts, our SFP/QSFP/XFP housings adopt standard Zamak3 zinc alloy one-piece die-casting. With compact structure, zero-deformation, superior EMI shielding and efficient heat dissipation, the housings effectively reduce module bit error rate and overheating failure. Automated mass production ensures stable quality and highly cost-effective solutions for global telecom clients.

Our full-series housings are widely applicable for global fiber communication equipment, perfectly compatible with 1.25G/10G/25G SFP/SFP28, 40G/100G QSFP/QSFP28 and 10G XFP transceivers, covering single-fiber, dual-fiber and RJ45 copper port modules. They are widely used in data centers, 5G base stations, industrial network and security monitoring systems.
