FAQs

What is SFP connector?

SFP is a compact, hot-pluggable network interface used to connect network switches with other devices for data transmission. The products support single-lane data rates from 100 Mbps to 224 Gbps. Based on mechanical structure, they are available in single-level and dual-level designs: Single-level / 1×N: includes a shielding cage and connector. Dual-level / 2×N: the shielding cage and connector can be integrated or separated.

What are the application areas for SFP connector products?

Key application areas for SFP HSIO connectors include: Cloud computing equipment: such as data-center storage systems, servers, routers, and switches. Telecom networks: telecom operators and equipment manufacturers, including scenarios such as 5G base stations.

What is the manufacturing process for SFP products?

The manufacturing process for SFP connectors covers product design, simulation and validation, mold design and fabrication, injection molding, stamping, plating, heat-sink manufacturing, and final assembly and testing. All processes are completed within GLGNET, supported by in-house developed automated assembly and test equipment. This integrated manufacturing model ensures strong competitive advantages in product quality, lead time, and cost control.

SFP cages selection recommendations and application processes?

Press-fit: recommended for convenient maintenance and stable quality. Soldering: suitable for high-performance requirements, but with higher material and process costs.

What standards do SFP HSIO connector products comply with, and what are the key specifications?

Complies with standards such as SFF MSA, IEEE 802.3, and CEI-OIF-4.0. Mechanical, electrical, and environmental performance meets the test requirements of EIA-364 and JESD22-A104.
Key specifications:
