Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect device reliability.

Notes
1. Internally AC coupled and terminated to 100Ω differential load.
2. Internally AC coupled, but requires a 100Ω differential termination or internal to Serializer/Deserializer.
3. Pulled up externally with a 4.7KΩ-10KΩ resistor on the host board to VCCT,R.
4. Mod_Def1 and Mod_Def2 must be pulled up externally with a 4.7KΩ-10KΩ resistor on the host board to V_CCT,R.

1. What is the difference between 1310 and 850 SFP?
A: D-net's 850nm wavelength is suitable for use in multi-mode SFPs, with a transmission distance limited to below 2 KM. On the other hand, the 1310/1550nm wavelength is appropriate for single-mode SFPs, enabling transmission distances exceeding 2 KM.

2. What is 1310 wavelength used for?
A: The 1310nm wavelength are mostly used for medium and long-distance transmission, of which 1310nm (SM, single mode, large loss during transmission but small dispersion, generally used for transmission within 40KM).

3. What is the speed of 1000BASE-LX SFP?
A: The D-net 1000BASE-LX40 SFP operates with a transmission rate of 1.25 gigabits per second, utilizes a working wavelength of 1310 nanometers, and is capable of transmitting data over a distance of 40 kilometers.
