Imported QSFP optical receiver

Imported QSFP optical receivers are high-speed, hot-pluggable modules that convert optical signals into electrical data for network devices, supporting data rates from 40 Gbps to 100 Gbps and beyond.

Overview

QSFP (Quad Small Form-factor Pluggable) optical receivers are part of the QSFP family of transceivers, designed for high-density, high-performance optical communication in data centers, enterprise networks, and telecommunications infrastructure . These modules integrate four independent electrical channels into a single compact form factor, enabling scalable bandwidth and efficient use of switch and router ports . They are hot-pluggable, allowing easy installation and replacement without powering down network equipment.

Types and Data Rates

• QSFP+: Supports 4 lanes of 10 Gbps each, totaling 40 Gbps aggregate bandwidth, suitable for 40 Gigabit Ethernet and InfiniBand applications .
• QSFP28: Increases per-lane speed to 25 Gbps, achieving 100 Gbps aggregate bandwidth, commonly used in 100 Gigabit Ethernet deployments .
• QSFP56 and QSFP-DD: Support 50 Gbps per lane and 8-lane configurations, enabling 200 Gbps to 400 Gbps aggregate bandwidth for modern high-speed networks .

Technical Features

Imported QSFP optical receivers typically include:

• LAN WDM channels: For QSFP28 LR4 modules, four wavelengths (e.g., 1295.56, 1300.05, 1304.58, 1309.14 nm) are used to multiplex/de-multiplex optical signals .
• High-sensitivity PIN photodiodes: Ensure accurate optical-to-electrical conversion for long-distance links up to 20 km or more .
• Digital diagnostics: Real-time monitoring of temperature, voltage, optical power, and signal integrity .
• Compliance with IEEE standards: Such as 100GBASE-LR4 for QSFP28 modules, ensuring interoperability with network equipment .
• Environmental resilience: Designed to operate under varying temperature, humidity, and EMI conditions .

Applications

Imported QSFP optical receivers are widely used in:

• Data centers: High-density switching and routing for 40G, 100G, and 200G networks .
• Telecommunications networks: Long-haul and metro optical links.
• Enterprise networks: High-speed backbone connections and server interconnects.
• AI and HPC clusters: Low-latency, high-bandwidth interconnects for compute-intensive workloads .

Considerations for Import

When sourcing imported QSFP optical receivers, consider:

• Compatibility: Ensure the module matches the switch/router vendor and QSFP generation.
• Reach requirements: Choose LR, SR, or ER variants based on link distance.
• Regulatory compliance: Imported modules should meet local safety and electromagnetic standards.
• Warranty and support: Verify vendor support for diagnostics and replacement. Imported QSFP optical receivers provide a reliable, high-performance solution for modern optical networks, combining compact form factor, high data rates, and robust operational features suitable for both short- and long-distance applications .
