    Frequently Asked Questions

    Q What is the maximum transmission distance supported by these SFP GE modules?

    The transmission distance varies by model, ranging from 550 meters (for multimode model ESP8512-05D) up to 160 kilometers (for single-mode model ESP5512-G0D).

    Q What type of fiber connector do these SFP modules use?

    All the SFP GE transceivers listed in the ordering information table use standard LC duplex connectors.

    Q What is the operating temperature range for these SFP transceivers?

    These SFP modules are rated for commercial operating temperatures ranging from 0°C to 70°C.

    Q What is the difference between VCSEL, FP, and DFB laser types?

    VCSEL lasers are typically used for short-range multimode applications (e.g., 550m). FP lasers are used for short to medium distances (up to 20km), while DFB lasers provide narrow spectral widths suitable for long-range transmissions (40km to 160km).

    Q Do these SFP GE transceivers support digital diagnostic monitoring (DDM)?

    Yes, the "D" suffix at the end of the part numbers (e.g., ESP8512-05D) indicates support for Digital Diagnostics Monitoring (DDM / DOM), allowing real-time monitoring of critical parameters.
