I am thinking about using different POS interfaces on dark-fibers. On one side, i already have POS-OC48-LR card (Cisco). This card use 1550 nm wave length. We would like to use a POS-OC48-SR (Cisco). This card use 1310 nm wave length. Are 1310 and 1550 optics comptatible ?
You have to have the same wavelength at both ends, otherwise it won't work.
If yes, i guess that there is impact on the power Budget available. How-Much ?!
LR tends to be 1550nm, because 1550nm has less signal loss over the same length of fiber.
