ANRITSU MS9720A 1450 to 1650 nm Optical Spectrum Analyzer

The Anritsu MS9720A is an optical spectrum analyzer with a diffraction grating that is used to measure and analyze optical spectra in the 1450 to 1650 nm band for WDM communications systems. A wavelength accuracy of ±20 pm is achieved over a range of 1530 to 1570 nm by performing calibration using the built-in wavelength reference light source. The MS9720A noise level is -87 dBm, so the tester is ideal for measuring the SNR of light sources used in WDM systems, as well as optical leakage and reflected light.
Range: 1450 to 1650 nm.
Accuracy: ±20 pm (1550 ±20 nm, room temperature), ±50 pm (1520 to 1600 nm), ±0.3 nm (all range) *After wavelength calibration.
Stability: ±5 pm (smoothing: 11 pt, 1 minute, at half-width of center wavelength).
Linearity: ±20 pm (1550 ±20 nm).
Read resolution: 5 pm (display resolution: 1 pm).
Setting resolution: 0.1, 0.2, 0.5, 1.0 nm (filter: 3 dB bandwidth).
Resolution accuracy: ≤±10% (1550 ±20 nm, 0° to 30°C), ≤30% (1550 ±100 nm, 0° to 30°C).

Measurement level ranges:
  -87 to +10 dBm (1450 to 1600 nm, 0° to 30°C), -72 to +10 dBm (1600 to 1650 nm, 0° to 30°C),
  -82 to +10 dBm (1450 to 1600 nm, 30° to 50°C), -67 to +10 dBm (1600 to 1650 nm, 30° to 50°C),
  -68 to +23 dBm (1450 to 1600 nm, 0° to 30°C, internal optical attenuator: on).
Accuracy: ±0.4 dB (1550 nm, -23 dBm).

Linearity: ±0.05 dB (1550 nm, -50 to 0 dBm).
Flatness: ±0.1 dB (1550 ±20 nm), ±0.3 dB (1520 to 1600 nm).

Polarization dependency: ±0.15 dB.
Dynamic range: 58 dB (at point 1 nm from peak), 53 dB (at point 0.5 nm from peak).
Optical return loss: 35 dB (1550 nm).
SLD output: >-40 dBm/nm (at 1550 nm).
Applicable fiber: 10/125 μm SM fiber (ITU-T G.652).
Optical connector: User replaceable (FC, SC, ST, DIN, HMS-10/A), Factory option (E2000, FC-APC, SC-APC, HRL-10).

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.
