The 40GBASE-ER4 QSFP+ module extends 40G transmission to 40 kilometers over standard single-mode fiber, answering metro and long campus requirements without external amplifiers.
The APD-based receiver provides the sensitivity needed for the extended link budget, while the compact QSFP+ housing keeps power and panel density in check for dense metro chassis.
