Product Highlights
2 km Long-Reach 40G Solution
- Specifically engineered for extended intermediate distances. It delivers robust 40Gbps connectivity at lengths up to 2 kilometers (2 km) over standard single-mode fiber (SMF), making it the ideal choice for regional data center interconnections, corporate campus backbones, and inter-building networks.
CWDM Technology for Maximum Fiber Efficiency
- Utilizes 4-channel Coarse Wavelength Division Multiplexing (CWDM) technology to multiplex four distinct wavelengths onto a single fiber pair. This architecture maximizes existing fiber infrastructure utilization, eliminating the need to lay new optical cables and drastically cutting cabling costs for long-reach applications.
Standard LC Duplex Interface for Simplified Deployment
- Equipped with a universal LC Duplex connector that is seamlessly compatible with mainstream single-mode fiber networks. It removes the requirement for complex parallel or proprietary cabling, allowing the use of conventional 2-strand single-mode patch cords to streamline structured cabling management.
Compact QSFP+ Form Factor for Ultra-High Density
- The standardized QSFP+ form factor supports high port density on modern enterprise switches and routers. This allows network administrators to efficiently scale 40G uplinks, boosting aggregate data bandwidth without consuming premium rack space or complicating thermal management.
Enterprise-Grade Cisco Interoperability & Proactive DOM
- 100% authentic Cisco quality (P/N: 10-3063-02) featuring an ergonomic yellow pull-tab for error-free identification and effortless hot-swapping. Integrated with Digital Optical Monitoring (DOM), it gives operators real-time visibility into telemetry data like Tx/Rx power and temperature to ensure mission-critical network uptime.
