Monitoring switch optical port and electrical port
Common optical port types for switches include 155M, 1. 25G, 10G, 25G, 40G, and 100G. When optical modules are installed on switches, it is necessary to read internal module parameters to monitor operating status, including link connectivity, real-time transmit/receive optical power, and temperature. As businesses scale, embrace hybrid work, and add more connected devices, switches quietly handle an ever-growing load. DOM is supported on MS120, MS125, MS130, MS210. Electrical ports (RJ45 interfaces) transmit electrical signals through twisted-pair cables and are the most basic connection method in industrial networks. Whether managing a small office or a large enterprise, visibility into port performance helps prevent issues like hardware faults, congestion, or unauthorized access from escalating into major disruptions. These reports are integral for meeting compliance needs.
