Product Review
The Juniper QFX-QSFP-40G-SR4 offers a 40 Gigabit Ethernet transmission over multimode fiber with a reach of up to 150 meters, catering well to high-density data center environments. However, its operating temperature range is limited to 0° to 40° C, potentially restricting deployment in environments with more extreme temperatures. Additionally, the module supports up to 128 link aggregation groups with 32 ports each, enhancing network flexibility and scalability, but its power consumption of 3.5W could impact overall energy efficiency in large-scale deployments.
