    Frequently Asked Questions

    Q: What is the transmission distance capability of SFP28 optical transceivers?

    A: Depending on the specific model, SFP28 transceivers support various transmission distances: SR (Short Range) supports up to 100m over multimode fiber, while LR, ER, and ZR models support distances ranging from 10km, 20km, 30km, 40km, up to 80km over single-mode fiber.

    Q: What is the difference between Commercial and Industrial temperature range SFP28 modules?

    A: Commercial temperature range modules (e.g., ESP852X-01D) operate between 0°C and 70°C, making them ideal for standard indoor data center environments. Industrial temperature range modules (e.g., ESP852X-01DI) are designed to withstand harsher conditions, operating reliably from -40°C to 85°C.

    Q: Which fiber optic connector type do these SFP28 transceivers use?

    A: All listed SFP28 optical modules in this ordering guide are equipped with standard LC duplex connectors, ensuring secure and low-loss optical fiber connections.

    Q: What laser and receiver types are configured in the 25G SFP28 series?

    A: These modules utilize VCSEL, DFB, or EML transmitters paired with PIN or APD/SOA receivers. For instance, short-range modules use VCSEL+PIN, mid-range modules use DFB+PIN/APD, and the long-range 80KM ZR module uses a high-performance EML+SOA+PIN configuration.

    Q: Are these SFP28 transceivers hot-pluggable?

    A: Yes, all these SFP28 transceivers are fully hot-pluggable, allowing you to install, replace, or upgrade modules without shutting down the host networking equipment, thereby minimizing system downtime.
