400G QSFP-DD DR4 1310NM 500M
The 400GBASE-DR4 optical transceiver is designed for high-speed data transmission in data centers, featuring an MTP/MPO-12 connector and supporting distances of up to 500 meters over parallel single-mode fiber. It complies with the QSFP-DD MSA, IEEE 802.3bs protocol, and 400GAUI-8 standards.
This module transmits a 400 Gigabit Ethernet signal across four parallel lanes, with each lane utilizing a single wavelength. It also supports a 4×100G breakout configuration for QSFP-DR-100G, making it a cost-effective and energy-efficient solution for 400GBASE data center applications.
The 400G QSFP-DD DR4 transceiver is designed for ultra-fast 400Gbps data transmission over single-mode fiber (SMF), making it an excellent choice for data centers and high-performance computing environments. With a parallel 4-channel architecture and PAM4 modulation, it ensures efficient, low-latency communication over distances of up to 500 meters. Featuring an MPO-12 connector, this transceiver is optimized for high-density deployments and supports breakout applications to 100G DR transceivers.
Designed for scalable, high-performance networking, the 400G QSFP-DD DR4 transceiver delivers the speed, efficiency, and reliability required for next-generation data center and enterprise infrastructures.
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 DR4 Optical Transceiver is a high-performance module designed for short-range communication over single-mode fiber (SMF) up to 500 meters. This transceiver operates on a PAM4 modulation scheme with an aggregate bit rate of 425Gbps, utilizing 8×53.125Gbps electrical lanes (400GAUI-8) and converting these into four 106.25Gbps optical channels for transmission. It features a 1310nm laser for data transmission and a PIN receiver for signal reception. Fully compliant with QSFP-DD MSA, IEEE 802.3bs standards, and EU Directive 2015/863/EU, this module is ideal for applications like 400GBASE-DR4 Ethernet and data center networking.
Operating on a single +3.3V power supply, the transceiver consumes a maximum power of 12W and is designed to function reliably within a temperature range of 0°C to 70°C. The QSFP-DD form factor supports digital diagnostic monitoring (DDM) via an I2C interface, allowing real-time tracking of operational parameters such as temperature, voltage, and optical power. Equipped with an MPO optical interface, the transceiver delivers robust performance, making it a dependable and efficient choice for high-speed, short-distance optical communication in modern networking environments.
