2.5Gbps SFP TRANSCEIVER MODULE
7. Digital Diagnostic Monitoring Accuracy
The diagnostic monitoring features external calibration, and is calibrated over operating temperature and
voltage range. The monitor parameters are represented as defined in SFF-8472.
These parameters of the monitoring accuracy are guaranteed, as long as operating conditions of this SFP
transceiver do not exceed ranges defined below.
