- Fiber Type Restriction : Optimized for multimode fiber only; not suitable for single-mode applications
- Wavelength Specific : Fixed 850 nm operation limits compatibility with other wavelength systems
- Protocol Specific : Primarily optimized for Gigabit Ethernet and 1x Fibre Channel protocols
## 2. Design Considerations
### 2.1 Common Design Pitfalls and Solutions
#### Power Supply Design
- Pitfall : Inadequate power supply filtering causing signal integrity issues
- Solution : Implement π-filter network (10μF tantalum + 0.1μF ceramic) at power input pins with proper grounding
#### Thermal Management
- Pitfall : Overheating in high-density applications leading to reduced reliability
- Solution :
- Ensure minimum 25 LFM airflow across module
- Maintain ambient temperature below specified maximum
- Consider thermal modeling in enclosure design
#### Signal Integrity
- Pitfall : Excessive jitter due to improper host board design
- Solution :
- Maintain characteristic impedance
