SFP Optical Transceiver Zinc Alloy Housing With Black Pull Tab

Product Overview
This SFP optical transceiver metal housing equipped with a black pull tab is a standard structural casing for fiber optical modules. Produced from high-quality Zamak zinc alloy through high-pressure die casting technology, the shell offers stable mechanical protection, excellent electromagnetic interference shielding and efficient heat dissipation for internal optical chips and circuit components. The specially designed hollow black pull tab is anti-slip and labor-saving, convenient for quick plugging and removal during server cabinet maintenance.
Manufacturing Process
High precision customized mold die casting, dimensional tolerance controlled within ±0.02mm
CNC secondary precision machining for assembly positioning structure
Multiple surface treatment options: nickel plating, tin plating, passivation anti-corrosion
Deburring, polishing, appearance inspection and pull tab assembly
Strict plugging fit test before factory delivery
Core Advantages
Excellent EMI Shielding: High conductivity zinc alloy effectively blocks electromagnetic interference to ensure stable high-speed signal transmission
Efficient Heat Dissipation: Optimized internal structure quickly conducts heat outward to extend optical module service life
User-friendly Black Pull Tab: Hollow anti-slip design, easy to pull and insert, greatly improving the efficiency of equipment maintenance
Ultra-high Assembly Precision: Perfectly matched with standard SFP cages, no loose assembly gap
Strong Durability: Wear-resistant, shockproof and anti-corrosion, suitable for long-term continuous operation in IDC computer rooms
