Explore our core portfolio of SFP cage modules, high-frequency SMT connectors, and magnetic RJ45 transceiver modules engineered for ultra-low latency applications.
As cloud computing, massive scale virtualization, and 5G telecommunications expand globally, hardware engineering teams face severe constraints surrounding signal integrity, electromagnetic interference (EMI), and thermal dissipation.
For high-frequency SFP connectors working at transmission rates of 5 Gb/s to 28 Gb/s and beyond (such as SFP28/SFP56 interfaces), the mechanical tolerances of contact gold plating play a critical role. Thick gold plating (e.g., 15u" and 30u" options) prevents contact oxidation and decreases contact resistance, directly lowering insertion loss and preventing reflection mismatches along the signal paths. SMT (Surface Mount Technology) connectors optimize capacitive parasitics compared to legacy through-hole designs, supporting cleaner eye diagrams in high-speed circuits.
High-density line cards operating in close proximity are highly susceptible to crosstalk and radiated emissions. High-performance SFP cages mitigate this through integrated EMI shielding structures. By combining press-fit pins, metal spring fingers, or elastomeric gaskets, the cage ensures a tight Faraday cage envelope around the module. In addition, multi-port ganged configurations (such as 1x6 or 2x8 SFP+ cages) use structural ground tabs to bridge the gap between the cage and the bezel panel, absorbing stray RF energy before it escapes the system enclosure.
Next-generation optical transceivers produce significant heat during peak performance. SFP cages feature integrated thermal ventilation holes and options for heatsink attachments to keep optical components within safe operational temperature envelopes. Furthermore, space-constrained front panels benefit from integrated light pipes (optical fibers molded directly onto the cage housing) to route status LED indicators from the host PCB directly to the front faceplate without compromising EMI integrity.
Technical Insight: Standardizing mechanical interfaces through the Multi-Source Agreement (MSA) ensures that compatible SFP cages and connectors interoperate seamlessly across diverse multi-vendor network environments. Zyqora interconnects are thoroughly tested for exact physical alignment and electrical compliance to match these standards.

Our manufacturing process is supported by comprehensive quality assurance procedures, including incoming material inspection, optical performance testing, aging tests, compatibility verification, and final product inspection. A dedicated team of 42 quality control professionals ensures that every product meets international standards and customer expectations.
As a company with both manufacturing and international trading capabilities, Zyqora has built a reliable supply network with more than 860 supply chain partners, enabling efficient sourcing, stable production, and flexible delivery schedules. Our primary customers include telecom operators, data center providers, system integrators, network equipment distributors, and enterprise IT solution providers worldwide.
Why global telecom leaders source SFP cages and connectors from China's advanced component clusters.
The manufacturing corridor in China integrates high-precision copper extrusion, precise plastic injection molding, and surface-mount packaging within a tight geographical area. This localization allows Zyqora to source high-grade phosphor bronze, beryllium copper, and flame-retardant LCP plastics quickly. Collaborating with over 860 supply chain partners enables us to shorten prototyping turnaround times to under two weeks, reducing time-to-market for global system integrators.
Managing high-frequency signals demands strict dimensional tolerances. To ensure reliable performance, Zyqora employs 42 quality control professionals. Every production batch undergoes automated optical inspection (AOI), X-ray plating thickness verification (to confirm 15u" or 30u" gold deposition), and network analyzer testing for insertion loss. Our manufacturing line complies with international standards, delivering CE, FCC, RoHS, and REACH certified components for smooth import clearance.
Standard components do not fit every custom housing. Last year, Zyqora designed and launched 168 new products, including custom height limits, modified press-fit layouts, and light pipe configurations. Backed by an engineering team of 65 R&D specialists, we provide custom high-speed firmware coding, specialized labeling, and mechanical packaging adjustments to match client-specific system layouts.

Deploying high-speed SFP interfaces across diverse operating environments and next-gen infrastructures.
Outdoor 5G macro stations and distributed edge computing units endure extreme temperature swings and high humidity. Using robust SFP cages with press-fit terminations ensures reliable electrical contact under mechanical stress. The inclusion of nickel-plated copper alloys protects against thermal expansion and galvanic corrosion, keeping cellular networks online in harsh environments.
Hyperscale environments pack dozens of transceiver modules onto a single rack unit. Ganged layouts (like 1x8 or 2x8 configurations) maximize front panel ports. In these setups, maintaining airflow and reducing crosstalk are critical. Advanced EMI-shielding gaskets and integrated heatsinks prevent thermal bottlenecks, allowing 25G and 100G architectures to run continuously without overheating.
The networking industry is moving past 28G NRZ signaling toward 56G and 112G PAM4 modulation schemes (QSFP-DD and OSFP). At these frequencies, standard PCB traces cause high attenuation. SFP cages must support Direct Attach Cables (DAC) and Active Optical Cables (AOC) with precise impedance matches. System architectures are also shifting toward Co-Packaged Optics (CPO), placing the optical engine closer to the ASIC. This requires highly specialized, low-profile SFP connectors to preserve signal integrity.
Answers to common engineering and sourcing questions about optical interconnects.
SMT (Surface Mount Technology) connectors are soldered directly onto surface pads on the PCB, providing low parasitic capacitance and excellent performance at high speeds. Press-Fit pins use mechanical force to wedge compliant pins into plated through-holes on the board. This creates a strong mechanical joint without soldering, making them easier to replace and highly resistant to thermal stress. As a result, Press-Fit is the standard choice for multi-port SFP+ cages.
Optical modules are frequently hot-plugged, causing mechanical wear on the connector contacts. Gold plating (available in 15u" and 30u" thicknesses) protects the underlying copper alloy from oxidation and wear. A thicker 30u" gold layer preserves low contact resistance over hundreds of insertion cycles. This maintains signal integrity at high speeds and helps prevent connection dropouts.
Metal spring fingers are durable, cost-effective, and provide sufficient EMI shielding for standard networking hardware. Elastomeric gaskets, which use conductive rubber, provide a tighter seal along the panel cutout. This makes them better suited for high-frequency systems (28 Gb/s to 56 Gb/s) that require strict containment of electromagnetic leakage.
