QSFP28 PSM4: PSM4, or Parallel Single-Mode Four, is a type of QSFP28 module that uses parallel single-mode fiber for transmission. It can reach distances of up to 2 kilometers.


QSFP28 CWDM4: CWDM4 (Coarse Wavelength Division Multiplexing) QSFP28 modules are designed for high-density data centers and enterprise applications. They use CWDM technology to transmit data up to 2 kilometers.


QSFP28 100G PSM4: This module can transmit data at 100 Gbps over a distance of up to 500 meters. It is widely used in data center interconnects.


QSFP28 100G LR4: Similar to the 100G PSM4, this module transmits data at 100 Gbps but is designed for longer distances, up to 10 kilometers over single-mode fiber.


QSFP28 eSR4: The Extended Short Range (eSR4) QSFP28 module is designed to provide high-speed connectivity for short distances, typically up to 70 meters over OM3 MMF.





Advantages of QSFP28


Scalability: QSFP28 modules provide a scalable solution for data centers and networking environments. They can easily be added or replaced, allowing networks to expand or adapt to changing requirements.


High Bandwidth: The 28 Gbps data rate of QSFP28 ensures that networks can handle the growing demands of data-intensive applications and services.


Energy Efficiency: QSFP28 is designed to be power-efficient, reducing operational costs and environmental impact.


Reliability: QSFP28 modules are built to stringent industry standards, ensuring the reliability of network connections.
