    Frequently Asked Questions

    What data rate do these SFP GE transceivers support?

    All the SFP GE modules listed in the ordering information support a standard data rate of 1.25G (Gigabit Ethernet).

    What type of connector is used for these modules?

    These SFP GE transceivers are equipped with standard LC duplex connectors for reliable fiber optic connectivity.

    What is the maximum transmission distance available?

    The transmission distance ranges from 550 meters (for multimode fiber using 850nm wavelength) up to 160 kilometers (for single-mode fiber using 1550nm wavelength with DFB+APD laser configuration).

    Do these SFP modules support Digital Diagnostics Monitoring (DDM)?

    Yes, the "D" suffix at the end of the part numbers (e.g., ESP8512-05D) indicates that these modules support DDM/DOM functions, allowing real-time monitoring of temperature, voltage, and optical power parameters.

    What operating temperature range can these transceivers withstand?

    These optical modules are designed for standard commercial operating temperature environments, ranging from 0°C to 70°C.

    What is the difference between PIN and APD receivers used in these modules?

    PIN photodetectors are typically used for short to medium-range transmissions (up to 80KM), while APD (Avalanche Photodiode) receivers offer much higher sensitivity (down to -34dBm) and are used for long-distance transmissions (120KM to 160KM).
