The Optical Module Solution for Juniper EX4650 Switch

  • April 15. 2023

Juniper EX4650 Ethernet switch provides Layer 2 and Layer 3 connectivity of 2 Tbps to networked devices such as security routers, servers, and other switches. The EX4650 is equipped with 48 line speed 10GbE/25GbE small pluggable optical module (SFP/SFP+/SFP28) ports and 8 line speed 40GbE/100GbE quad core SFP+optical module (QSFP+/QSFP28) ports in a compact 1U platform, providing flexible support for mixed 1GbE, 10GbE, 25GbE, 40GbE, and 100GbE environments. Below, ETU-LINK will help you match corresponding transmission products based on the type of port.
