One of the key features of this 400G QSFP-DD transceiver is its use of single-mode fiber, which ensures minimal signal loss and superior signal integrity across medium-range distances. The module is optimized for a maximum transmission distance of 500 meters, making it ideal for inter-rack and intra-data center connections where high bandwidth and low latency are critical. This distance capability allows network architects to design scalable and flexible network topologies without compromising on performance.

Power efficiency is a crucial consideration in high-speed optical modules, and this 400G QSFP-DD fiber module excels in this area with a maximum power consumption of only 12 watts. This low power profile helps reduce operational costs and cooling requirements within data center environments, contributing to a greener and more sustainable network infrastructure. Despite its energy-efficient design, the module does not compromise on performance or reliability.

The transmitter technology employed in this module is based on Vertical-Cavity Surface-Emitting Lasers (VCSELs). VCSEL transmitters are known for their high-speed modulation capabilities, low power consumption, and excellent beam quality. By leveraging VCSEL technology, the 400G QSFP-DD transceiver achieves reliable and high-speed data transmission with improved signal quality and reduced error rates. This makes it an ideal choice for applications requiring ultra-high bandwidth and minimal downtime.

In terms of electrical interface, the module features a sophisticated 4x53.125GBd PAM4 signaling architecture. This electrical interface supports four lanes of 53.125 gigabaud each, utilizing Pulse Amplitude Modulation 4-level (PAM4) signaling to effectively double the data rate over conventional NRZ signaling methods. The 4x53.125GBd PAM4 interface enables the module to deliver the full 400 Gigabit Ethernet throughput, ensuring compatibility with the latest networking equipment and standards.

Designed for ease of integration, the 400G QSFP-DD fiber module is compatible with the QSFP-DD form factor, which is widely adopted in the industry for high-density, high-performance network deployments. This compatibility allows network operators to upgrade their existing infrastructure with minimal disruption while achieving significant improvements in bandwidth and network efficiency. The module’s compact design also facilitates high port density in data center switches and routers, maximizing space utilization and scalability.

In summary, the 400G Optical Module represents a state-of-the-art solution for high-speed optical networking.
