EXFO IQS-3150-B 65 dB SM Variable Attenuator Module

The Exfo IQS-3150-B variable attenuator features an extremely rugged design that only uses two moving parts-a rotating motor for the shutter and a linear motor for the filter-and state-of-the-art electronics. The attenuator’s optomechanical assembly was tested at its highest operating temperature, at a very high relative humidity level, and with a continuous incident optical power of 23 dBm at 1550 nm.

Wavelength range: 1250 to 1650 nm.
Maximum attenuation: ≥ 65 dB.
Insertion loss: 1.0 dB (Typical), 1.5 dB (Maximum).
Attenuation setting resolution: 0.002 dB (Typical).
Attenuation linearity: ±0.1 dB.

Spectral uniformity, 1510 nm to 1605 nm: ±0.05 dB.
Spectral uniformity, 1450 nm to 1630 nm: ±0.09 dB (Typical).
PDL, peak-to-peak: 0.15 dB.
Return loss: 60 dB (Typical).
Maximum input power: 23 dBm.
Transition speed: up to 23 dB/s (Typical).

Coherence Length
Average distance over which superimposed waves lose their phase relationships

Linewidth is the width of a spectral line in terms of wavelength, wave number and frequency.

Power Flatness Versus Wavelength
When changing the wavelength at constant power setting and recording the differences between actual and displayed power levels, the power flatness is ± half the span (in dB) between the maximum and the minimum of the measured power levels.

Spectral Width
Spectral Width is the wavelength interval over which the magnitude of all spectral components is equal to or greater than a specified fraction of the magnitude of the component having the maximum value. In optical communications applications, the usual method of specifying spectral width is the full width at half maximum. This is the same convention used in bandwidth, defined as the frequency range where power drops by less than half (at most -3 dB).

Telecom Bands
Optical fiber communications typically operate in a wavelength region corresponding to one of the following Bands. O Band (original): 1260–1360 nm. E Band (extended): 1360–1460 nm. S Band (short wavelengths): 1460–1530 nm. C Band (conventional): 1530–1565 nm. L Band (long wavelengths): 1565–1625 nm. U Band (ultralong wavelengths): 1625–1675 nm
