    Frequently Asked Questions

    Q: What is the maximum transmission distance supported by these SFP28 transceivers?

    The transmission distance varies by model, ranging from 100 meters over multi-mode fiber (SR) up to 80 kilometers over single-mode fiber (ZR) using EML+SOA+PIN technology.

    Q: What is the difference between ESP852X-01D and ESP852X-01DI?

    The primary difference is the operating temperature range. ESP852X-01D is designed for commercial temperature ranges (0 to 70°C), while ESP852X-01DI is built for industrial environments, operating reliably from -40 to 85°C.

    Q: Do these SFP28 modules require specific fiber optic connectors?

    Yes, all the listed SFP28 transceivers in this series feature standard duplex LC connectors for optical connections.

    Q: What wavelength options are available for these 25G SFP28 transceivers?

    Depending on the distance requirements, they are available in 850nm (for short-range SR), 1310nm (for medium to long-range LR and ER), and 1309nm (for ultra-long-range ZR).

    Q: What laser and receiver types are utilized in the 30KM and 40KM ER modules?

    Both the ESP312X-30D and ESP312X-40D-D modules utilize a high-performance DFB (Distributed Feedback) laser paired with an APD (Avalanche Photodiode) receiver to ensure high sensitivity over long distances.
