   EXFO FOT-930 (FOT 930)   Description / Specification:    
EXFO FOT-930 Multifunction Loss Tester Series

EXPO’s FOT-930 Multifunction Loss Tester series is designed to help network service providers address CAPEX and OPEX issues, enable installers to easily adapt to all network types, and provide CATV operators with a single-unit solution to their back reflection, fiber length, high power and bidirectional loss measurement needs. Combined with its video fiber inspection probe, this unit also enables the easy detection of dirty or damaged connectors, providing a clear view of connectors and fiber ends on the FOT-930 series’ high-resolution display.

Models included in the series are the FOT-932, the FOT-932X, and the FOT-933.

Broadband Source (BBS)
A Broadband Source is a spectrally large source that emits a signal which contains a continuous range of frequencies with a broad optical bandwidth (usually 100 nm or more). Sometimes called a white light source, there are two different meanings of this term. Visible white light and a source which does not necessarily emit in the visible spectral region.

Coherence
Coherence is the pattern and or relationships of waves due to phase properties.

Linearity
Linearity is the relative difference between the displayed power ratio, Dx/D0, and the actual (true) power ratio Px/P0 caused by changing the displayed power level from the reference level, D0, to an arbitrary displayed level, Dx.

Power Flatness Over Modulation
When changing the wavelength and modulation frequency, and measuring the differences between actual and displayed power levels (in dB), the power flatness is ± half the span between the maximum and the minimum value of all differences.

Singlemode fiber
Singlemode Fiber has a small core, only about 9 microns, and is used for telephony and CATV with laser sources at 1300 and 1550 nm. It can go very long distances at very high speeds. Both multimode and singlemode fiber have an outside diameter of 125 microns - about 5 thousandths of an inch - just slightly larger than a human hair.
