Cisco CMPT-RTX-6-1290 Modular headend digital transmodulator6dBm, 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.

General Features

- Designed to operate within the Cisco Compact Nodes (A90100/A90300, A90200, A90201)
- Variable modulation depth (RF drive level) promotes superior link optimization
- RF input test point
- 5-MHz pilot tone for easy setup
- Nonvolatile storage of preset operating parameters
- Remote optical modulation index (OMI) setting, when supported by node
- Burst mode for interoperability in RFoG
- 0 dBm DFB
- 3 dBm and 6 dBm, DFB available in 16 CWDM wavelengths
- Uncooled DFB lasers with Isolator for exceptional performance and low power consumption

Multiple setup and control options

- Local control with front panel or Cisco Handheld Programmer Terminal Model 91200
- Advanced element management (status monitoring and control) interface
