FAQs

Q: Does this require dispersion compensation?
A: At 1310 nm over 40 km, dispersion compensation is typically not required; verify your link budget and OS2 G.652 fiber for best results.

Q: Is ER4 interoperable with LR4?
A: No. ER4 and LR4 are different reach classes and are not intended to interoperate across a link.

Q: Is FEC required?
A: Not typically for standard 40 km links, but follow your platform’s recommendations for long-reach optics.
