Frequently Asked Questions
Q What is the maximum transmission distance supported by these CWDM SFP28 modules?
Depending on the specific model selected, these CWDM SFP28 transceivers support transmission distances of 10KM (ESCxx2X-10D), 20KM (ESCxx2X-20D), and up to 40KM (ESCxx2X-40D) over single-mode fiber (SMF).
Q Which wavelengths are available for the 25G CWDM SFP28 transceivers?
The 10KM and 20KM models operate within the 1270nm to 1370nm wavelength range. The long-distance 40KM model operates within the 1270nm to 1330nm range to optimize signal integrity over extended spans.
Q What is the difference in laser and receiver types between the 10KM/20KM and 40KM models?
The 10KM and 20KM models utilize a DFB laser paired with a PIN receiver, suitable for standard reach applications. The 40KM model uses a high-performance EML laser combined with an APD receiver to achieve higher receiver sensitivity (-18 dBm) required for long-distance links.
Q What type of optical connector do these transceivers use?
All models in this series are designed with standard duplex LC optical connectors, ensuring compatibility with standard fiber patch cables.
Q What are the operating temperature limits for these modules?
These CWDM SFP28 transceivers support a commercial operating temperature range of 0°C to 70°C, making them ideal for standard data center and enterprise networking environments.
