Doubling Down on 400G Optical Transceivers
As the UAE cements its position as a global AI powerhouse, industry leaders like G42 and Khazna Data Centers are spearheading the region's infrastructure expansion. At the core of this transformation is 400G optical transceiver technology, unlocking the ultra-fast throughput and low latency required for massive LLM training and high-density compute fabrics.

Frequently Asked Questions
Technical and procurement details for deploying 400G transceivers in UAE data centers.
What is the difference between QSFP-DD and traditional QSFP28 modules?
QSFP-DD (Double Density) features an 8-lane electrical interface operating at up to 50G PAM4 per lane, delivering 400Gbps total throughput, whereas QSFP28 uses 4 lanes of 25G NRZ for 100Gbps. QSFP-DD ports remain backward-compatible with QSFP28 modules.
How does 400G ZR simplify Data Center Interconnect (DCI) links?
400G ZR modules integrate coherent digital signal processors (DSP) directly into the standard pluggable QSFP-DD form factor, enabling router-to-router connections over metro DWDM networks without requiring external transponder chassis.
Can SFPS.AE provide custom coded optics for mixed-vendor data center fabrics?
Yes. Our in-house optical engineering lab codes each module to precisely match host switch specifications across Cisco, Arista, Juniper, NVIDIA, and other major OEM platforms, ensuring plug-and-play validation.
