The Viavi (JDSU) E81DISPAP is an Optical Dispersion Measurement (ODM) module for MTS/T-BERD-6000 and MTS/T-BERD-8000 optical test platforms. The E81DISPAP offers combined long range CD, PMD and attenuation profile module (1260-1640nm).

Chromatic Dispersion:

• Two-ended test using one fiber based on phase shift method
• Full wavelength range characterization
• Suitable for any fiber type
• High dynamic range up to 55 dB

Polarization Mode Dispersion:

• Based on the fixed analyzer method using fast Fourier transform (FFT)
• Established in the market
• High dynamic range up to 65 dB

Attenuation Profile:

• dB loss/km over the full wavelength range: 1260-1640 nm
• Allows CWDM and DWDM transmission band characterization
• Water peak (1383 nm area) characterization

Some of the cutting edge features of the E81DISPAP include the following:

• Test through non-bidirectional components, including erbium doped fiber amplifiers (EDFAs) and filters
• Very fast acquisition time (from 40 to 80 seconds) with minimum 500 acquisition points
• Accurate zero-wavelength characterization on G.652 fiber
• One input port for any test configuration
