The ILX Lightwave DPM-79810 is a dual-channel power meter module for the FOM-7900B Multi-Channel Fiber Optic Test System mainframe. It enables simultaneous monitoring of two independent optical signals within a modular test platform. This is a legacy product no longer sold or supported by ILX Lightwave or Newport. No technical support, repair services, calibrations, or official documentation are available from the manufacturer.
## Technical Specifications
The DPM-79810 functions as a dual power meter integrated into the FOM-7900B mainframe architecture. It interfaces with compatible fiber optic source modules covering wavelengths from 1475 nm to 1625 nm with typical output power levels of 9–20 mW depending on module configuration. The host mainframe provides GPIB/IEEE-488.2 remote control and automation capabilities.
## Key Features
• Dual independent optical power measurement channels
• Integration with FOM-7900B multi-channel test system
• Compatible with fiber optic source modules (FOS-79800E series) and switching modules
• GPIB/IEEE-488.2 remote command interface via mainframe
• Operating temperature range: 0 °C to 40 °C
• Maximum relative humidity: <80% RH (non-condensing)
## Environmental & Installation Requirements
Modules must be installed and removed only when the mainframe is powered off. All handling should occur at an ESD-protected workbench with proper operator earth grounding to prevent damage.
## Compatibility & Integration
The DPM-79810 is not a standalone instrument. It operates exclusively as a module within the ILX Lightwave FOM-7900B mainframe. The mainframe accepts multiple module types, including fiber optic sources and switching elements, supporting integrated multi-channel test configurations. Users seeking this obsolete module should source from secondary markets and understand that manufacturer support is unavailable.
