Starview 400G QSFP-DD SR4.2 BiDi Optical Transceiver Module
Introducing our new product, 400GBASE-SR4.2 — the Starview high-performance 400Gbps QSFP-DD SR4.2 BiDi Optical Transceiver Module, designed to deliver exceptional high-speed performance, flexible compatibility with a wide range of networking equipment, and energy-efficient data transmission for high-density modern networks.
Powerful 400G to 4x100G Breakout Capability
The 400G QSFP-DD SR4 BiDi Optical Transceiver Module supports breakout connections to 4 x 100G QSFP-100G-SR1.2 modules, using MPO to LC breakout cable. This flexibility enhances large-scale deployment scenario, especially in cloud data center and core network transitioning to 400G infrastructure.
The optical transceiver module transmits two bidirectional wavelengths per fiber across four parallel MMF pairs, enabling efficient bandwidth utilization, reducing fiber count and cabling complexity.
The 400G QSFP-DD SR4 BiDi Optical Transceiver Module leverages PAM4 modulation and bi-directional 850nm/910nm wavelengths over OM4 or OM5 multimode fiber (MMF). It is capable to transmit data up to 70 meters over OM3 and 150 meters over OM5, making it ideal for data center interconnect, 400G Ethernet network, and High-Performance computing environment.
