400G QSFP-DD SR8 850NM 100M
The 400GBASE-SR8 optical transceiver is equipped with an MTP/MPO-16 connector and supports transmission distances of up to 100 meters over parallel OM4 multi-mode fiber. It adheres to the IEEE 802.3bs protocol and the 400GAUI-8/CEI-56G-VSR-PAM4 standard.
Designed for high-speed data transfer, this module transmits a 400 Gigabit Ethernet signal across eight wavelengths. The device manages multiplexing and demultiplexing internally, ensuring efficient data distribution. Additionally, it supports 2 × 200G-SR4 and 8 × 50G-SR configurations, making it a flexible solution for advanced networking applications.
The 400G QSFP-DD SR8 transceiver is engineered for next-generation data center and high-performance computing networks, delivering blazing-fast 400Gbps connectivity over multimode fiber (MMF). With an 8-lane parallel architecture and PAM4 modulation, it ensures efficient, low-latency transmission while minimizing power consumption. Designed for short-reach applications up to 100 meters, it is the ideal solution for high-density, high-speed interconnects.
Built for AI workloads, cloud computing, and high-speed data center interconnects, the 400G QSFP-DD SR8 transceiver delivers the performance, scalability, and reliability required for the most demanding networking environments.
We stand by the exceptional quality of our optical transceivers, which is why we offer a lifetime warranty—giving you complete confidence in performance, reliability, and long-term value.
The 400Gbps QSFP-DD SR8 Optical Transceiver is a high-performance module designed for short-range data communication over multimode fiber (MMF). It features 8 full-duplex channels, each capable of transmitting up to 53Gbps, resulting in an aggregate bandwidth of 400Gbps. Utilizing an 850nm VCSEL array for transmission and a PIN photodetector array for reception, this module operates over OM3 fiber for distances up to 70 meters and OM4 fiber up to 100 meters, with Forward Error Correction (FEC). The transceiver is housed in a hot-pluggable QSFP-DD form factor and uses an MPO16 APC optical connector, ensuring compatibility with modern networking systems.
Operating with a +3.3V power supply and consuming less than 8.5W, the transceiver is energy-efficient and reliable within a case operating temperature range of 0°C to 70°C. It incorporates internal Clock and Data Recovery (CDR) circuits on both transmitter and receiver channels for enhanced signal integrity. Digital diagnostics monitoring (DDM), accessible via a two-wire interface, allows real-time monitoring of temperature, voltage, and optical power. Fully compliant with QSFP-DD MSA standards, IEEE 802.3cd, and RoHS regulations, this transceiver is ideal for high-speed, short-range Ethernet applications in data centers and cloud networking environments.
