Optical module SFF interface manufacturers

Leading manufacturers of SFF optical modules include LINK-PP, Chengdu Gigac Technology, and Amphenol, offering compact, reliable, and high-performance transceivers for embedded and industrial networking applications. Key Manufacturers and OfferingsLINK-PP specializes in soldered SFF optical modules designed for permanent integration onto PCBs. Their products, such as the LF5-SC3501-40IDL and LF5-SM3101-10AI, support bidirectional single-fiber links and 1G Ethernet over single-mode fiber, providing low-latency, high-reliability performance for FTTH deployments, industrial automation, and embedded network hardware.

LINK-PP modules are ISO-certified, RoHS-compliant, and Telcordia-tested, emphasizing long-term durability and thermal stability. Chengdu Gigac Technology offers the SFF 2x5 series, which includes single-fiber (SC interface) and dual-fiber (LC interface) transceivers. These modules support speeds from 155Mbps to 2.

5Gbps and transmission distances from 300m to 160km, with military-grade and extended-grade options for harsh environments. They feature low EMI, excellent ESD protection, and operate from a single 3. 3V supply.

Amphenol provides a broad range of SFF optical transceivers, including SFP, SFP+, XFP, and QSFP28 modules. Their products support duplex, BiDi, CWDM, and DWDM applications, with LC or MPO interfaces. Amphenol modules are widely used in data centers, telecom, and high-speed networking, offering low power consumption, high reliability, and compliance with IEEE and MSA standards.

Applications and AdvantagesSFF optical modules are ideal for embedded systems, industrial Ethernet, telecom access layers, and data center interconnects. Their soldered design ensures mechanical stability, thermal efficiency, and reduced failure rates compared to pluggable modules. They support multiple communication standards, including Ethernet, SONET/SDH, ATM, and Fibre Channel, enabling broad interoperability.

Summary

For sourcing SFF optical modules, LINK-PP, Chengdu Gigac Technology, and Amphenol are prominent manufacturers offering a range of compact, high-performance, and industrial-grade transceivers. Selection depends on required interface type (SC, LC), data rate, transmission distance, and environmental tolerance, making these manufacturers suitable for both embedded and high-density networking applications.
