Frequently Asked Questions (FAQ)
What is the difference between SFP+ SR, LR, ER, and ZR/eZR modules?
These designations represent the transmission distance and fiber type support:
- SR (Short Range): Up to 300m over Multimode Fiber (MMF) at 850nm.
- LR (Long Range): Up to 10km or 20km over Singlemode Fiber (SMF) at 1310nm.
- ER (Extended Range): Up to 40km over Singlemode Fiber (SMF) at either 1310nm or 1550nm.
- ZR / eZR (Zeal Range / Enhanced ZR): Up to 80km or 100km over Singlemode Fiber (SMF) at 1550nm.
What connectors do these 10G SFP+ transceivers use?
All the optical transceivers listed in this ordering information sheet utilize standard LC duplex connectors for fiber optic cabling connectivity.
Why do longer-distance modules (ZR/eZR) use APD receivers instead of PIN?
APD (Avalanche Photodiode) receivers provide higher sensitivity compared to standard PIN receivers. This allows ZR (80KM) and eZR (100KM) modules to detect much weaker optical signals over long-distance single-mode fiber links.
Do these transceivers support Digital Diagnostics Monitoring (DDM/DOM)?
Yes, all modules listed support DDM/DOM interface standards. This allows network administrators to monitor real-time parameters such as optical output power, receiver sensitivity, operating temperature, and voltage.
What is the operating temperature range for these SFP+ transceivers?
These modules are designed for standard commercial operating temperature ranges of 0°C to 70°C, making them ideal for enterprise data centers and indoor networking environments.
