ILX LIGHTWAVE FOM-7900B Multi-Channel Fiber Optic Test System

The ILX Lightwave FOM-7900B Multi-Channel Fiber Optic Test System supports up to eight modules of stabilized DFB or Fabry Perot laser sources, fiber optic switches or dual power meters. All are controlled from a single user interface. The mainframe and modules can be controlled by a GPIB/IEEE-488.2 or RS-232 interface. Up to twenty-five FOM-7900B Systems can be linked to control up to 200 channels from one GPIB address. Specifications. Internal Modulation; Waveform: Square Wave. Frequency: 1 to 500 kHz.

Coherence Time
Average time for the wave train to lose its phase realtionships

Fiber Bragg Grating (FBG)
A fiber Bragg grating (FBG) is a type of distributed Bragg reflector constructed in a short segment of optical fiber that reflects particular wavelengths of light and transmits all others. This is achieved by adding a periodic variation to the refractive index of the fiber core, which generates a wavelength specific dielectric mirror. A fiber Bragg grating can therefore be used as an inline optical filter to block certain wavelengths, or as a wavelength-specific reflector.

Modulation is the process by which the characteristic of one wave (the carrier) is modified by another. Adding information into pulses of light.

Power Linearity
When changing the power level and measuring the differences (in dB) between actual and displayed power levels, the power linearity is ± half the span (in dB) between the maximum and the minimum value of all differences.

Stability is the extent to which a specified property, characteristic, or parameter of a substance, device, or apparatus, such as a fiber optic transmission system, remains fixed with the passage of time or with varying environmental conditions.
