Notes:
1. Frequency response for transmitter (Tx) module only. Does not include the frequency response contribution of an optical
receiver.
2. This is the RF level that produces 100% composite Optical Modulation Index (OMI) with a 0 dB Tx input pad at room
temperature. This is used for reference purposes only and is NOT the recommended RF drive level. Consult with Cisco Sales
Engineering group in order to determine the appropriate RF drive level for a particular application.
3. The RF level measured at the Tx module’s RF test point is relative to the Tx module RF input as specified, with a 0 dB input
pad installed.
