What does the "ER4" stand for?

by E***o on 02/12/2025

"ER4"can be interpreted as: E = Extended (indicating a long-range module) R = Range (refers to the distance, 40km for ER4) 4 = Four wavelengths (indicating that the module uses four different wavelengths for data transmission) For the ER4 module, it typically refers to an extended range (up to 40km) and four wavelengths for data transmission, used in applications like 40GBASE-ER4 Ethernet.
