MAP - Multiple Application Platform

MAP – MAP is the measuring system developed by VIAVI for industrial and laboratory use. There are different measuring platforms available that vary in their number of connection slots. For these platforms plug-in modules for various measurements are available, such as, for example, light sources, filters, or optical switches.

MAP Light Sources and EDFAs

Light sources and amplifiers for the MAP system: broadband sources, LED sources, Fabry Perot lasers, tunable DBR lasers, and erbium-doped fiber amplifiers

Description

The MAP system is used in a large variety of applications. The variety of available MAP light sources is just as large.

Broadband light source – mBBS
with a high power density in the C band and high spectral stability
Tunable DBR laser – mTGL
The tunable distributed Bragg reflector (DBR) plug-in module is a tunable laser for the C band with 50 GHz of channel spacing.
Erbium-doped fiber amplifier – mEDFA
EDFAs are low noise and feature high optical power output and high amplification

MAP Broadband Light Source mBBS

The mBBS broadband light sources utilize the advantage of erbium technology: amplified spontaneous emission (ASE), which provides a smoothed power density in the C band. The spectral stability of the source is very high.

MAP BBS Features

Output power with smoothed spectrum
High output power density
High spectral stability

MAP Tunable DBR Laser mTLG

The mTLG modules can be set to all DWDM wavelengths in the C band with 50 GHz of channel spacing. The wavelength and output power are adjusted using the MAP platform controller module – either locally or remotely with the help of a PC interface. The internal wavelength locker and power control circuit ensure wavelength stability and output power stability.

MAP TLG Features

Configuration with one, two, or four channels
Tunable in the C band
Wavelangth tunability: up to 42 nm
Channel spacing: 50 GHz

MAP Erbium-doped Fiber Amplifiers (EDFAs)

Erbium-doped fiber amplifiers are optical amplifiers that strengthen an optical input signal without having to electro-optically convert it first. This amplification is based on the stimulated emission of the signal to be enhanced. The modulation of the signal is irrelevant; it does not change. The EDFAs are thus referred to as “transparent.”

Optical amplifiers are used in network technology; for example, they serve as signal amplifiers when bridging large distances, such as in transatlantic fiber optic connections.

In EDFAs, sections of the fiber are doped with erbium and then optically pumped using a semiconductor laser. The mEDFAs manufactured by Viavi exhibit an output power between 12 dBm and 21 dBm. They feature a low noise of just 3.5 dB and an amplification profile with a flatness of better than 2.0 dB.
