Description

Sealight’s SL-ChromaFlex 1.2 GHz SL-DMTx4 directly modulated C-Band DWDM transmitter combines high performance with the highest density platform enabling operators to conserve precious headend space.

Ideally suited for short to medium range node segmentation and the migration to node+0 and DOCSIS® 3.1. The SL-DMTx4 is available in three configurations to support different levels of density and RF combining configurations.

The SL-DMT24 and SL-DMT34 offer two and three ITU transmitters respectively per module along with separate internal RF combining of broadcast/narrowcast signals. The SL-DMT44 allows operators to take advantage of the highest density with four ITU transmitters per module for applications where the broadcast/ narrowcast signals are externally combined.

Each version is housed in a single-slot SL-ChromaFlex module using rear-facing blind mating RF connectors, supporting hot-swappable modules with a fixed mid- plane allowing rapid replacement without disconnecting RF cables. Front panel optical LC/APC connectors and F-81 common test point selectable for each RF input.

Features

  • Bandwidth: 50-1218 MHz
  • Dual/Triple/Quad transmitters per module
  • High-Density Design: Up to 16 transmitters per RU
  • Transmitter versions are available in any wavelength combination and in the ITU Interoperable Wavelength Plan Groups 1 through 4
    • SL-DMT24 – Two ITU lasers with common broadcast and two narrowcast inputs
    • SL-DMT34 – Three ITU lasers with common broadcast and three narrowcast inputs
    • SL-DMT44 – Four ITU lasers with individual, unicast RF inputs
  • Optional output port configurations
    • Multiplexed single output
    • Multiplexed single output with express port
    • Individual wavelength outputs
  • Front access
    • LC/APC optical output connectors
    • Selectable RF test point
    • LED indicators for RF and optical power alarms
  • Local and remote status monitoring and management via SNMP, CLI, and web-based GUI
