Cisco CMPT-RTX-3-1290 Modular headend digital transmodulator

3dBm, 1290nm, CWDM laser, pigtail SA/APC connector All transmitters feature a built-in microprocessor and pilot tone for easy set-up of the reverse path. The pilot tone does not take up any reverse bandwidth as it is placed at 5 MHz. Moreover, placing the pilot tone at 5 MHz also makes the reverse transmitter interoperable with virtually all reverse receivers in the marketplace. If there is no modulation, the pilot tone serves as a quieting tone, which reduces spurious noise and improves overall noise performance with up to 15 dB. All reverse transmitters have increased gain, which allows low reverse input levels at the node.

The reverse transmitter can also run in burst mode which makes it possible to deploy Cisco Compact Nodes in a radio frequency over glass (RFOG) network.
