2.5Gps SFP TRANSCEIVER MODULE
7. Digital Diagnostic Monitoring Accuracy
The diagnostic monitoring features internal 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.

8. Selective Bandwidth filtering function
Receiver bandwidth is selected by accessing over the 2-wire serial Interface according to SFF-8079 &
SFF-8089 from the host.
Each bit rates for the selective bandwidth and adaptable protocols are as follows.
a) 155Mbps setting
b) 622Mbps setting
c) 1.062Gbps setting
d) 1.25Gbps setting
e) 2.125Gbps setting
f) 2.488Gbps setting
