Starview Coherent 400G High Power QSFP-DDs are deployed for Long-Distance Optical Transmission
Project Background
A leading network operator requires transmission expert to help in their optical infrastructure upgrade to 400Gbps, and to meet their growing demand for bandwidth to enhance their service delivery nationwide.
The Challenge
Their existing fiber infrastructure presented significant challenges due to high signal loss. With standard 400G ZR+ optics attaining only fiber budget of -6 to -7dB, this is insufficient for their long-distance connectivity. In addition, optical amplifiers or boosters must be included in the design, which impacts overall project budget and return on investment (ROI).
The Perfect Solution
Recognizing their challenges, the operator approached Starview Technologies for recommendation. We proposed our SV-QSFP-400G-HZR+, a 400G coherent high power optical module to support fiber budget of 20–23dB. This eliminates the need for optical amplifiers, and reduces the costs and project complexities.
Key Benefits:
- Cost Savings: The Operator avoided the complexities and expenses of amplifiers/boosters.
- Simplified Deployment: A streamlined solution without additional equipment
- Environmental Impact: Reduced energy consumption and carbon footprint, aligning with ESG goals
Starview’s Transceivers
Starview’s 400G ZR+ and 400G HZR+ modules cater to the diverse needs of network operators and data center providers. Our SV-QSFP-400G-HZR+ enhances flexibility and performance in networks that has OADMs (Reconfigurable Optical Add-Drop Multiplexers) or OTN (Optical Transport Network).
Why Choose Starview’s 400G HZR+
- Enhanced Performance: Higher transmit power and receiver sensitivity
- Versatility: Supports applications such as extended point-to-point transmission, metro/regional OTN, and multi-vendor ecosystems
- Optimized OSNR: Improved Optical Signal-to-Noise Ratio minimizes transmission errors
- Programmable: Can be programmed to be compatible in any network equipment that supports QSFP-DD
For links under 80 km, Starview 400G PAM4 Ethernet is the ideal choice. For long-haul networks exceeding 80 km, or integrating with DWDM, 400G DCO QSFP-DD is the preferred choice.
