CE Certified 40G Optical Router

CE-certified 40G optical routers use QSFP+ transceivers compliant with IEEE 802.3ba and QSFP MSA standards, supporting high-speed 40Gbps connectivity for data centers, enterprise, and metro networks.

Overview

A CE-certified 40G optical router typically supports 40 Gigabit Ethernet (40GbE) using QSFP+ (Quad Small Form-Factor Pluggable) modules, which are hot-swappable and interoperable with IEEE-compliant 40GBASE interfaces . These routers are designed for high-density switching, routing, and long-distance optical links, ensuring reliable performance in data centers, enterprise cores, and service provider networks .

QSFP+ Transceiver Options

1. Short-Reach (SR4) Modules
   • Supports multimode fiber (OM3/OM4/OM5)
   • Link lengths: 100–150 meters
   • Uses MPO/MTP connectors
   • Ideal for intra-data center connections
2. Long-Reach (LR4) Modules
   • Supports single-mode fiber (OS2)
   • Link lengths: up to 10 km
   • LC duplex connectors
   • Suitable for enterprise campus or metro networks
3. Extended Reach (ER4) and 80 km Modules
   • ER4: up to 40 km over single-mode fiber
   • 80 km QSFP modules: for metro-scale or inter-city links
   • Uses four LAN-WDM wavelengths for extended optical budget
   • Maintains QSFP+ form factor for compatibility with existing 40G routers

Key Features

• Standards Compliance: IEEE 802.3ba 40GBASE, QSFP MSA, CE and RoHS certified
• Bandwidth: 40 Gbps aggregate, with 4 channels of 10 Gbps each
• Diagnostics: Digital Optical Monitoring (DOM/DDM) for real-time performance monitoring
• Power and Form Factor: Single +3.3V supply, QSFP+ pluggable design
• Temperature Range: 0°C to 70°C for standard modules

Deployment Considerations

• Compatibility: Ensure transceivers are tested with the router or switch vendor (e.g., Cisco Catalyst or Nexus series) for full interoperability
• Fiber Type: Choose multimode for short distances and single-mode for long distances
• Distance Requirements: Select SR4, LR4, ER4, or 80 km modules based on link length
• Network Upgrade Path: CE-certified 40G routers allow migration from 10G to 40G Ethernet while maintaining compliance with European safety and environmental standards

Conclusion

CE-certified 40G optical routers paired with QSFP+ transceivers provide high-performance, standards-compliant 40GbE connectivity for a variety of network environments. By selecting the appropriate transceiver type—short-reach, long-reach, or extended-reach—network engineers can optimize link distance, reliability, and interoperability while ensuring CE and RoHS compliance .
