Summary

Very Low STSE to Characterize Deep Wells

The figure below plots optical power transmission through two

matched, narrow notch filter fiber Bragg grating reflectors

measured with the 4200. The ratio of the signal power to the

total integrated ASE background power outside the 0.8 nm filter

width is >70 dB.

Rugged & Reliable

The 4200 is one of the most reliable Tunable Laser Source

available. Our experience in combination with that of New

Focus in designing and developing deployed tunable lasers has

helped make the 4200 a factory tunable laser with the quality of

a deployable laser. Shock and vibration are fully specified to

ISTB Procedure 2B. This is the eighth-generation tunable laser,

and our lasers are inside more test equipment than any other

suppliers’.

Low Noise, High Speed, Versatile and Low

Cost

The 4200 Tunable Laser Source (TLS) is a fast, low noise

tunable source designed as a reliable high-performance

workhorse for a variety of applications. For passive optical

component testing, the TLS and either the dBm Component

Spectrum Analyzer (CSA) or the 4500 IL/PDL/ORL Swept

Spectrometer are designed to work hand-in-hand for fast,

high accuracy characterization of Insertion Loss, PDL, and

Return Loss (ORL).

Wide Tuning Range

With standard tuning range of 150 nm, the 4200 can cover

both edges of the C and L bands and well into the S band.

Optimized Coherence Control

The 4200’s narrow line width is a blessing for some

applications. However, for a complicated factory test

system where intrinsic etalons can create severe optical

noise, we offer Coherence Control. This line-broadening

source of optical noise reduction is especially critical for PDL

measurement, where even low levels of optical noise can

wreak havoc with measurement integrity. Coherence

Control can also have very beneficial effects when multiple

flat connections (FC/PC or FC/UPC) connections exist in the

optical path.
