The Photonetics OM 3646RA00 Mainframe is an 8-slot chassis that serves as the platform for multi-wavelength test systems using OM Series modules. Designed to accommodate up to eight TUNICS-OM tunable laser modules, this 19″ rack-mountable instrument provides the control and integration infrastructure for compact, modular laser sources across the C-band and L-band spectral regions.

• Modulation Input Range: 0–4 V
– Key Features
• Individual modulation input on each installed module with ≥1 GHz bandwidth
• Automatic power control via adjustable diode driver for each channel
• Single-turn knob for optical power adjustment in automatic-power-control mode
• Analog outputs for laser diode current monitoring across all 8 channels
• “Lim” indicator alerts when maximum diode current is reached without achieving set power level
• Multi-turn wavelength adjustment knob on TUNICS-OM modules
• Rear panel: 8 BNC output connectors (one per module slot) plus 1 BNC input connector
– Typical Applications
• Multi-wavelength optical test and measurement systems
• Tunable laser source platforms for network characterization
• Laboratory and field test environments requiring compact, modular configuration
– Compatibility & Integration
The OM 3646RA00 is engineered specifically for Photonetics OM Series modules. The mainframe is commonly deployed as a standalone chassis; plug-in modules are ordered separately. Each installed TUNICS-OM module integrates full laser control, modulation capability, and power monitoring into the unified chassis architecture.
