The 400GBASE-DR4 QSFP112 PAM4 1310nm 500m DOM MPO-12/APC SMF Optical Transceiver Module is engineered for high-speed data center interconnects and enterprise network applications that require reliable and efficient data transmission. This module operates at a data rate of 400Gb/s and employs advanced PAM4 modulation technology, which increases data density by encoding four distinct signal levels within a single transmission channel. This method maximizes bandwidth utilization while maintaining signal integrity, even in environments where channel noise is a concern.
Utilizing a 1310nm laser, the module is optimized for single-mode fiber (SMF) applications. The 1310nm wavelength not only ensures compatibility with existing SMF infrastructures but also supports transmission distances of up to 500 meters. This extended reach is achieved through careful optical design that balances power output with controlled signal attenuation, making the module suitable for various data center layouts and campus network configurations where longer fiber spans are required.
A prominent feature of this optical transceiver is its integrated Digital Optical Monitoring (DOM) capability. DOM provides real-time monitoring of essential operational parameters, including optical power levels, temperature, and supply voltage. This functionality is critical for maintaining network performance, as it allows network administrators to quickly identify and address potential issues before they affect overall system reliability. By continuously monitoring these parameters, the module ensures that the optical link operates within optimal conditions.
Compliance with industry standards is another key aspect of this design. The module supports MSA specifications and adheres to CMIS 5.2, ensuring seamless integration with a wide range of network equipment. The MPO-12/APC connector interface is designed to deliver secure and low-loss connectivity, which simplifies installation and improves overall system performance. Additionally, the QSFP112 form factor supports high port density, making it an efficient solution for modern data centers that require compact, high-performance components.
The 400GBASE-DR4 QSFP112 PAM4 optical transceiver module delivers practical performance for demanding network environments. Its robust technical design, emphasis on reliability through DOM, and compatibility with standard SMF systems make it a sound choice for network operators seeking to achieve high-speed, stable connections over extended distances without unnecessary embellishment.
