Frequently Asked Questions (FAQ)
Q
What is the difference between SFP+ SR and SFP+ LR modules?
SFP+ SR (Short Range) is designed for short-distance transmissions up to 300 meters over multimode fiber using an 850nm wavelength. SFP+ LR (Long Range) supports longer transmission distances up to 10km or 20km over single-mode fiber using a 1310nm wavelength.
Q
Which module should I choose for a transmission distance of 40km?
For a 40km transmission requirement, you can choose either the ESP31X-40D (operating at 1310nm with DFB+PIN) or the ESP55X-40D (operating at 1550nm with EML+PIN), depending on your system's wavelength and fiber infrastructure requirements.
Q
What type of connector is compatible with these SFP+ optical transceivers?
All the 10G SFP+ modules listed in our ordering table feature standard duplex LC connectors for reliable and low-insertion-loss optical connectivity.
Q
What is the maximum transmission distance supported by this product series?
The maximum transmission distance in this series is 100km, supported by the ESP55X-A0D SFP+ eZR module, which utilizes a high-performance 1550nm EML laser and an APD receiver.
Q
Are these SFP+ modules suitable for industrial temperature environments?
The models listed here are designed for commercial operating temperature ranges of 0°C to 70°C. If you require industrial-grade operating temperatures (-40°C to 85°C), please contact our support team for customized solutions.
Q
How can I access the detailed technical specifications for each module?
You can download the comprehensive PDF data sheet for any specific Part Number (P/N) by clicking the corresponding "DOWNLOAD" button in the "Data Sheet" column of the ordering table above.
