●Industry Trends & Product Positioning
With 5G densification, cloud resource pooling, and enterprise digitalization, legacy optical networks face three critical challenges:
Bandwidth Wall: Live streaming/AI training demands 400G/channel transmission.
Space Constraints: Metro sites require 1RU high-density design to save 70% rack space.
Multi-service Convergence: Legacy SDH and modern 25G/400G Ethernet coexistence.
The CL-OTN-3900-04 addresses these needs through Opto-Electronic Co-Design:
✓ 96λ×400G=38.4T total capacity
✓ Smooth evolution from 10G/100G networks
✓ 30% OPEX reduction via multi-protocol integration
●Technological Innovations
1.Ultra-Compact Hardware
3D Thermal Design: Aerodynamic guide slots + intelligent fans improve cooling by 40%
Hybrid PSU: AC/DC/HDC compatibility with global certifications (EN 61000-4-5)
Front-access Maintenance: 45° angled ports reduce maintenance space by 40%
2.Intelligent Optical Layer
Dynamic Power Equalization: SOA amplifiers control fluctuation ≤0.5dB
Auto-Tuning Lasers: ITU-T G.694.1 compliance, wavelength switching<2ms<>
Dispersion Compensation: Built-in DCM modules (±1000ps/nm range)
●Deployment Scenarios
| Scenario | Solution | Value Proposition |
| 5G Fronthaul | Ring topology + 1+1 protection | 3μs latency for eCPRI interfaces |
| Finance | Dual-star + SNCP | Zero-loss failover for active-active DCs |
| Smart City | Multi-level OSU pipes | Isolate government/traffic/medical flows |
| Submarine | Repeater + Enhanced FEC | BER<1e-15, 5x="" reliability="" improvement=""> |
●Lifecycle Management
Deployment: CL-Toolkit generates optical power budget reports.
Operations: AI predicts laser degradation 48hrs in advance.
Evolution: Hardware-ready for 800G, SDN control via OpenDaylight.
The CL-OTN-3900-04 OTN-WDM subsystem embodies the philosophy of "Maximum Density, Full-service Support, Zero Compromise", converging optical and data technologies to deliver end-to-end 400G solutions for 5G fronthaul, cloud-network convergence, and mission-critical networks. With its modular design, intelligent optical layer, and lifecycle services, it not only addresses today's 38.4T capacity demands but also paves the way for 800G/1.6T evolution, serving as the foundational infrastructure for next-generation elastic optical networks.
