Product Description:
The 400G QSFP-DD SR8 optical transceiver is a high-performance module designed for data centers and high-speed networking applications. This transceiver utilizes advanced PAM4 modulation and supports various 400G Ethernet configurations. It is engineered to deliver superior performance and reliability for short-reach applications up to 100 meters over multimode fiber (MMF).
Key Features:
* Modulation Technique: PAM4
* Standards Compliance: Supports 400GBASE-SR8, 2 x 200G-SR4, and 8 x 50G-SR
* Form Factor: QSFP-DD (Quad Small Form-factor Pluggable Double Density)
* Data Rates: Capable of 400 Gbps data rate
* Reach: Up to 100 meters over OM4/OM5 multimode fiber
* Connector Type: MTP/MPO-16 (APC)
* IEEE 802.3cd, QSFP-DD MSA, CMIS 4.0
* VCSEL 850nm
Supported Configurations:
1. 400GBASE-SR8: Provides 400 Gbps Ethernet connectivity using eight parallel 50 Gbps lanes.
2. 2 x 200G-SR4: Supports dual 200 Gbps Ethernet links using four parallel 50 Gbps lanes each.
3. 8 x 50G-SR: Enables eight independent 50 Gbps Ethernet links, ideal for breakout applications.
Benefits for Cloud Infrastructure Networking:
1. High Bandwidth: With 400 Gbps throughput, it supports the growing demand for high-speed data transmission in modern data centers.
2. Scalability: Supports multiple configurations (400G, 2x200G, 8x50G), providing flexibility to adapt to various networking requirements.
3. Reduced Latency: Ensures low-latency data transfers, critical for cloud services and applications that require real-time processing.
4. Energy Efficiency: Designed to consume less power per gigabit compared to lower-speed transceivers
5. Space Efficiency: The compact QSFP-DD form factor allows for higher port density on switches and routers
6. Ease of Deployment: Compatible with existing multimode fiber infrastructure, simplifying upgrades to higher-speed networks
