Datasheet

Overview

The VIAVI Multiple Application Platform (MAP) Broadband Source (mBBS-C1) is a third-generation design based on erbium-doped fiber. It delivers 100 mW of amplified spontaneous emission (ASE) across the extended C-band and the L-band. The output is depolarized and spectrally flat to within 1.8 dB, and its power stability is better than 0.02 dB.

The module is used to measure optical components and to test telecommunications transmission. Typical uses include spectral measurements of couplers, WDMs, isolators and other passive components, noise loading during OSNR compliance tests, power loading of optical amplifiers during gain and noise figure measurements, and polarization mode dispersion (PMD) measurements. Because its output power is very stable, the source is often used to calibrate optical power meters and variable attenuators.

Optical design

The optics consist of an erbium-based gain block and supporting optical components. They are designed to deliver maximum output power at the bulkhead-mounted optical connector. In addition to the single-band C-band and L-band versions, the datasheet lists dual-output C-band versions with a 50/50 or 30/70 power split.

Platform and control

The mBBS belongs to the MAP LightDirect module family, alongside attenuators, polarization scramblers, power meters and spectrum analyzers. It works with all current MAP-300 and MAP-200 chassis, which hold 2, 3 or 8 application modules in rack-mount or benchtop form. The platform has an LXI-compliant web interface for multiple users, SCPI-based automation drivers and IVI drivers. Its graphical interface switches between a summary view and a detailed view of each module.
