As data demands continue to surge, businesses need cutting-edge networking solutions that deliver ultra-fast, high-bandwidth connectivity. At Carritech Optics, we specialise in high-performance optical transceivers. These are designed to power next-generation data centres, telecom networks, and cloud infrastructures.
With full OEM compatibility, industry-leading reliability, and a lifetime warranty, our 400G optical transceivers offer a cost-effective alternative to OEM-branded modules—without compromising performance.
What Are 400G Optical Transceivers?
400G optical transceivers are advanced networking modules that enable ultra-high-speed 400Gbps data transmission over fiber optic networks. Designed to support high-density, high-bandwidth applications, these transceivers are essential for scaling data centres, enterprise networks, telecom infrastructure, and AI-driven applications.
The most common type of 400G transceiver is the QSFP-DD (Quad Small Form-Factor Pluggable Double Density), which supports eight lanes of 50Gbps, using PAM4 modulation to achieve 400Gbps throughput while maintaining power efficiency and a compact footprint.
Key Features of 400G Optical Transceivers:
- 400Gbps Data Rates – Ultra-fast speeds for high-performance networking.
- Compact QSFP-DD Form Factor – Designed for high-density deployments.
- PAM4 Modulation – Improves bandwidth efficiency and transmission quality.
- Full OEM Compatibility – Seamlessly integrates with Cisco, Juniper, Arista, Huawei, Nokia, Dell, and more.
- Multiple Reach Options – Available in SR8, DR4, FR4, and LR4 variants for different distances and network needs.
- Hot-Swappable – Allows easy installation and replacement without downtime.
How Do 400G Optical Transceivers Work?
A 400G optical transceiver acts as an interface between network hardware and fiber optic cables. The transceiver converts electrical signals into optical signals (and vice versa), enabling data to be transmitted over long distances at extremely high speeds.
These transceivers play a critical role in:
- Data centers – Enabling high-speed connections between servers, storage, and networking equipment.
- Telecom networks – Supporting the backbone of 5G infrastructure and high-capacity fiber-optic networks.
- Cloud computing – Ensuring seamless, ultra-fast communication between cloud servers and data hubs.
- AI & HPC (High-Performance Computing) – Facilitating high-bandwidth, low-latency connections for AI workloads.
Thanks to QSFP-DD’s backward compatibility, these optical transceivers can also work alongside existing 100G and 200G systems, allowing for a cost-effective, scalable network upgrade.
