Frequently Asked Questions
Q: What is the maximum transmission distance for these SFP Copper-T modules?
The maximum transmission distance for all listed SFP Copper-T modules (ES-T0-R, ES-T1-R, ES-T2-R, and ES-T3-R) is 100 meters over standard Category 5e or better copper cabling.
Q: What connector type do these SFP Copper modules use?
These modules are equipped with a standard RJ45 connector interface, allowing you to connect standard copper Ethernet patch cables directly to your SFP ports.
Q: What are the differences in data rates among the ES-T series models?
The models support different data rates: ES-T0-R supports 2.5G; ES-T1-R supports fixed 1000M (1Gbps); ES-T2-R supports 10/100/1000M auto-negotiation; and ES-T3-R supports 10/100M auto-negotiation.
Q: What is the operating temperature range for these transceivers?
These SFP Copper transceivers support a commercial operating temperature range of 0°C to 70°C, making them suitable for standard indoor networking environments.
Q: Why are the wavelength, output power, and sensitivity listed as "N" in the table?
The "N" stands for Not Applicable. Because these are copper transceivers using electrical signals over RJ45 connectors, they do not utilize optical lasers, wavelengths, or optical power measurements.
Q: How can I download the official data sheets for these products?
You can easily download the comprehensive data sheets by clicking the "DOWNLOAD" button in the table corresponding to the specific Part Number (P/N) you require.
