Frequently Asked Questions
1. What fiber types are compatible with these SFP GE transceivers?
Compatibility depends on the wavelength and distance. For example, the ESP8512-05D (850nm) uses Multi-Mode Fiber (MMF) for short distances up to 550m. Models like ESP3112-10D (1310nm) or ESP5512-80D (1550nm) require Single-Mode Fiber (SMF) for long-distance transmissions up to 10km and 80km respectively.
2. What is the difference between VCSEL, FP, and DFB lasers listed in the specifications?
VCSEL lasers are cost-effective and typically used for short-range transmission (up to 550m) over multi-mode fiber. FP (Fabry-Perot) lasers are suitable for mid-range transmission (up to 40km), while DFB (Distributed Feedback) lasers offer narrower spectral width and higher performance, making them ideal for long-reach applications (40km to 160km).
3. Are these SFP optical modules hot-swappable?
Yes, all listed SFP GE transceivers are hot-pluggable. This allows you to install or replace the modules without powering down the host network switch or router, minimizing network downtime.
4. What temperature range do these SFP modules support?
These modules support a commercial operating temperature range of 0°C to 70°C, which is suitable for most standard enterprise, office, and data center environments.
5. How do I access the detailed datasheet for a specific model?
You can easily download the technical specifications datasheet by clicking the "DOWNLOAD" button next to the corresponding Part Number (P/N) in the ordering information table above.
6. What type of connector interface is used on these transceivers?
All SFP GE transceivers in this ordering table utilize standard duplex LC connectors to ensure secure and reliable fiber optic patch cable connections.
