The FOM-7900B is a high-performance fiber-optic test and development platform with eight channels supporting plug-in laser sources. This system provides a cost-effective solution for WDM and CWDM test applications including EDFA, SOA, and fiber optic component characterization.

Front panel plug-in modules are offered at user-specified wavelengths from 1475-1625nm including service channels at 1310, 1480, 1510, and 1625nm. Each channel can be tuned over a 1.7nm range with 0.001nm resolution. These sources can be customized to meet special requirements including fiber optic connector type, PM alignment and fiber, and center wavelength on ITU grid points.

For higher density WDM system requirements, up to 25 additional FOM-7900B mainframes can be linked together for a total of 200 channels, all controlled from a single GPIB address.

Performance for EDFA Testing

For gain flatness testing with accurate attenuator-like performance, the FOS-79800F modules feature high-resolution attenuation so that you can easily equalize channel levels. Attenuation is accurate within ±0.1dB, while maintaining other specifi cations from maximum
power to 5dB down. If speed is critical to your application, the optional SS-810 shutter blocks the output, effectively turning off the source without turning off the current to the lasers, eliminating settling time.

For measuring EDFA spontaneous emission background levels, the FOS-79800F modules feature 100% depth and 50% duty cycle modulated drive current to the lasers. Each source can be modulated synchronously at any frequency from 1-500kHz.

Normal and inverted TTL-level outputs provide flexible triggering for data acquisition instruments, simplifying test setup. In addition, a rear panel modulation input synchronizes multiple mainframes and allows synchronization of the system with an external instrument.

Multi-Channel Module Control

Each FOM-7900B module can be controlled independently through an intuitive menu on the front panel or remotely through the GPIB/IEEE-488 interface. Easy-to-understand commands allow full control of each module’s control parameters. Banked remote capability provides control of up to two hundred source, switch, and power meter functions from a single GPIB address.

Remote Control for Automated Testing

For complete automated control, the 7900B system comes with a powerful GPIB interface, allowing remote programming and control from most computers. This interface uses the National Instruments TNT488 chip-set, which supports high-speed GPIB protocol. All instrument functions accessible from the front panel are also accessible through the interface bus, and all commands are based on a set of easy-to-use mnemonics. For further control fl exibility, LabVIEW^® instrument drivers are available at no additional cost.
