I would like to know if there is any differences between Optical interfaces using 1310nm or 1300nm. Can a 1310nm interface be used with a 1300nm interface? Please help.

 

850nm and 1300nm light wavelenghts are produced by LEDs and are standards for multimode fiber. 1310nm and 1550nm light wavelengths are produced by laser diodes and are standards for single mode fiber. 1300nm and 1310nm are considered a single wavelength (1300nm) by NIST for devices they design or test.

 

The answer is "likely"... while transmitters produce light at a very narrow wavelength, the receivers generally receive a much wider spectrum of light. You'll find a kind of bell-curve forms centered on the target wavelength, with "loss" increasing the farther you stray from the target wavelength.

Can you mix 1300nm and 1310nm devices? If you're talking about a well-made fiber runing 30 feet, then you'likely have no problem. If you're trying to squeeze 20 miles out of the system, you'll fail. I cannot suggest at what length/cable loss the answer changes from "no problem" to "no way".
