QSFP28 100G Data Rate 10km LC Duplex Singlemode. Add this QSFP module to your CCR2216, CRS504, or CRS518 setups for distances of up to 10 kilometers and enjoy true speed and ultimate reliability. This optical module provides four independent full-duplex channels with up to 25 Gbit/s bandwidth per channel and a total bandwidth of 100 Gbit/s. The module features built-in digital diagnostic functions such as optical power monitoring. It includes integrated digital diagnostics for parameters like optical power, transceiver supply voltage, temperature, laser bias current monitoring, and other critical parameter monitoring. These options can be helpful in alerting the user to abnormal transceiver activity and when certain customizable operational thresholds are exceeded. The monitoring allows you to plan proactively, make informed decisions, and predict necessary upgrades or maintenance based on the transceiver's performance.
