Spectrum Analysis

Agilent 86120B/C and 86122A Multi-Wavelength Meters

•

Characterize WDM spectra during R&D, manufacturing

and commissioning

•

Wavelength accuracy up to ±0.2 ppm

•

Simultaneously measure wavelengths and powers of up

to 1000 channels

•

Automatic optical signal-to-noise ratio measurements

•

Automated measurement routines and data logging

As the demand for access to more information increases, the need

for greater capacity on transmission systems drives component

manufacturers and network equipment manufacturers to push their

capabilities to new limits. The successful design and deployment of

DWDM systems requires that stringent performance criteria are met in

order to guarantee quality of service. With Agilent multi-wavelength

meters, you will be able to address these demands with confidence.

The Performance You Need – When You Need It

The Agilent family of multi-wavelength meters is just that – a family.

Each model uses compatible SCPI remote commands. You pay for only the

performance you need, when you need it. If your requirements become

more demanding in the future, you can substitute another Agilent multi-

wavelength meter, avoiding unnecessary cost and time developing new

code for your test system. With the new 86122A, you can upgrade to a

unit with the best performance available. Agilent multi-wavelength meters

allow you to optimize test costs while protecting your investments.

Simultaneously Measure up to 1000 Wavelengths and Powers

The Agilent 86120B, 86120C and 86122A multi-wavelength meters,

like other, Michelson interferometer-based wavelength meters, allow

you to measure the average wavelength of the input signal. In addition,

the Agilent multi-wavelength meters – with advanced digital processing –

accurately and easily differentiate and measure up to 1000 (200 and 100

for the 86120C and 86120B, respectively) discrete wavelengths.

Agilent multi-wavelength meters simultaneously measure the

individual powers of discrete wavelengths, offering the following

measurement capabilities:

•

1 to 1000 wavelengths and powers

•

Average wavelength and total power

•

Up to ±0.2 ppm wavelength accuracy

•

Up to 5 GHz wavelength resolution

•

Calibrated for evaluation in air or vacuum

•

Wavelength units in nm, THz, or wave number (cm-1)

•

Amplitude units in dBm, mW, or µW

•

OSNR and averaged OSNR for WDM SONET/SDH systems

•

Rugged design to withstand strong shocks and vibrations

WDM Transmission Systems

Combining measurement performance with reliability, the Agilent

multi-wavelength meters allow easy and accurate verification of

optical carrier performance in transmission systems by measuring,

wavelength, power and optical signal-to-noise ratios during design

and manufacturing test. The 86122A multi-wavelength meter is

optimized for measuring ultra-dense channel spacing with an absolute

wavelength accuracy of up to ±0.2 ppm (±0.3 pm referenced to 1550 nm).

With a resolution of <5 GHz, it is an ideal solution for the design and

manufacturing of next-generation optical networks.

With a rugged and portable package, the 86120B and 86120C

multi-wavelength meters are ideal for optical network commissioning

and monitoring applications. With the 86120C resolution of <10 GHz

(<20 GHz for the 86120B) and absolute wavelength accuracy of ±2 ppm

or ±3 pm at 1550 nm (±3 ppm, ±5 pm at 1550 nm for the 86120B),

you can confidently verify system performance of DWDM systems with

channels spaced at <50 GHz.

Sources

The superior wavelength and amplitude measurement capabilities of

the Agilent 86120B, 86120C and 86122A multi-wavelength meters

enable maximum performance of your components. You can measure

DFB, FP or multiple DFB laser wavelengths and amplitudes during

burn-in, environmental evaluation, final test and incoming inspection.

Calculate center wavelengths of broader linewidth sources, such as

LED’s or Bragg-Gratings filtered ASE responses, using the user-selectable

broadband algorithm.
