Products Description
Designed for the most demanding environments, this series delivers stable, high-capacity bidirectional communication using dense wavelength division multiplexing (DWDM) technology. By separating transmit and receive signals over dual fibers, we ensure maximum signal integrity over ultra-long distances.
Key Highlights:
- Versatile Performance: Supports multi-rate data transmission from 1.25Gb/s to 25Gb/s, adaptable to various network generations.
- Ultra-Long Reach: Capable of bridging distances up to 160 km, ideal for connecting remote industrial sites, power grids, and transportation systems.
- Seamless Integration: Built on the standard SFP+ form factor with wide equipment compatibility, offering a low-risk, plug-and-play solution for evaluating new suppliers or expanding existing DWDM infrastructure.
Who This Product Is Designed For
This DWDM SFP+ series is designed for customers who:
- Operate long-distance optical links where stability is critical
- Maintain industrial or infrastructure networks with long service lifecycles
- Need to add or qualify a new DWDM supplier
- Require drop-in replacement without system redesign
- Work in environments with wide temperature variation or limited maintenance access
Typical Challenges in DWDM Projects
In real-world DWDM deployments, customers often face:
- DWDM modules approaching end-of-life or supplier discontinuation
- Performance instability over long distances and extended operation
- Harsh environments with temperature extremes, vibration, and EMI
- Difficulty servicing remote or unmanned sites
- Risk associated with introducing a new supplier into an existing system
How This DWDM SFP+ Series Reduces These Risks
- Dual-fiber DWDM architecture ensures stable optical transmission
- Broad data rate support covers both legacy and upgraded systems
- Transmission distances up to 160 km over SMF
- Wide temperature grades suitable for industrial environments
- Standard SFP+ package allows direct integration and phased evaluation
- Engineering support focused on replacement and validation, not just sales
