🚀 800G OSFP 2×DR4 Optical Transceiver: Scalable Speed for Modern AI & Cloud Networks
By Optech – The Professional Optical Transceivers Manufacturer
In the age of artificial intelligence, hyperscale computing, and cloud transformation, data center infrastructure must evolve rapidly to keep up with bandwidth-hungry applications. The 800G OSFP 2×DR4 optical transceiver answers that call—offering two independent 400G DR4 channels in a single high-performance OSFP form factor.
Engineered for high-density, low-latency environments, the 800G OSFP 2×DR4 module is a critical building block in next-gen Ethernet and AI cluster deployments.
🔧 Technical Overview: What Is 800G OSFP 2×DR4?
The 800G OSFP 2×DR4 is a hot-pluggable transceiver compliant with the OSFP MSA, integrating two full 400G DR4 optical engines into one module. It operates over single-mode fiber (SMF) with PAM4 modulation, offering up to 2×400Gbps = 800Gbps total data throughput.
