Compatible QSFP High-Speed ​​Optical Connectors

High-speed QSFP connectors, including QSFP+, QSFP28, QSFP56, and QSFP112G, are available from South Asian suppliers such as AUK (Taiwan) and Wuhan RayOptek (China), supporting data rates from 10 Gbps up to 400 Gbps per port.

Overview of QSFP Connectors

QSFP (Quad Small Form-factor Pluggable) connectors are widely used in data centers, telecom, and networking applications. They support multiple channels in a single pluggable interface, enabling high-speed data transfer:

• QSFP+: Supports 40 Gbps aggregate bandwidth, backward compatible with SFP+
• QSFP28: Supports 100 Gbps, backward compatible with QSFP+
• QSFP56: Supports 200 Gbps aggregate bandwidth
• QSFP112G: Supports 400 Gbps aggregate bandwidth with 112G PAM4 per channel, designed for next-generation high-density systems These connectors offer low insertion loss, EMI containment, and thermal management options such as heat sinks and airflow-optimized cages .
