Frequently Asked Questions
Q: What is the difference between SFP28 SR, LR, ER, and ZR transceivers?
The primary differences lie in their transmission distance, wavelength, and laser source. SR (Short Range) works up to 100m over multimode fiber at 850nm. LR (Long Range) supports up to 10km/20km at 1310nm. ER (Extended Range) covers up to 30km/40km, while ZR (Zero Range) reaches up to 80km over single-mode fiber using advanced EML+SOA+PIN technologies.
Q: Can I use these SFP28 transceivers in standard SFP+ ports?
SFP28 modules physically fit into SFP+ ports, but compatibility depends on the host switch. Most SFP28 modules can be configured to run at 10G speeds, but they will not run at 25G in an SFP+ port. It is recommended to check your hardware specifications beforehand.
Q: What is the operating temperature range of the ESP852X-01DI model?
The ESP852X-01DI is an industrial-grade transceiver designed to operate reliably in extreme environments, supporting a temperature range from -40°C to 85°C. This is in contrast to commercial-grade models which operate from 0°C to 70°C.
Q: What type of connectors do these SFP28 modules utilize?
All models listed in the ordering information table utilize standard duplex LC connectors, providing secure and reliable fiber optic connectivity.
Q: Do these transceivers support Digital Diagnostics Monitoring (DDM)?
Yes, all the listed SFP28 transceivers feature built-in Digital Diagnostics Monitoring (DDM), allowing real-time tracking of parameters such as laser temperature, optical output power, optical input power, and transceiver supply voltage.
