Introduction

The Keysight Technologies 8160xx Family of Tunable Laser Sources offers the full wavelength range from

1240 nm to 1650 nm with no wavelength gaps. All 8160xx Tunable Laser Sources are modules for the Keysight

8164B Lightwave Measurement System mainframe. This provides test instrumentation with maximum

exibility.

Investing in the Keysight 8160xx Family of Tunable Laser Sources can realize the cost efciency and

performance required to test components for coarse and dense wavelength division multiplexing (CWDM,

DWDM, 100GBASE-LR4) and passive optical networks (PON).

Fast Two-Way Sweeps and High Power with Low SSE

The new Keysight 81606A top-line Tunable Laser Source has been designed to reach a new accuracy level

and to increase test efciency by enabling faster swept-wavelength tests and lower cost of ownership. It

accelerates the automated adjustment of wavelength-selective devices in the new two-way sweep mode up to

200 nm/s speed with sub-picometer repeatability and best-in-class accuracy. With more than +12 dBm output

power at the product family’s lowest spontaneous emission level, it enables the validation of extremely deep

lters.

Through a major redesign, the new Keysight 81606A Tunable Laser Source reaches:

– 15 dB more dynamic range through high signal power at lowest spontaneous emission, enabled by the new

cavity and laser module design.

– A 4-fold improvement in absolute accuracy with increased real-time tracking speed and

resolution, enabled by the novel wavelength reference unit.

– Faster sweeps at up to 200 nm/s in both directions without impacting the specied dynamic accuracy,

enabled by enhanced feedback controls and drive mechanics.

The new value and basic line models share the 81606A’s new design with low spontaneous emission and

narrow line width, its industry-leading power repeatability and long-term stability. The new modules offer

additional price-performance options based on output power, tuning speed, wavelength accuracy and

repeatability. Whether you need to verify the design of demanding optical components or adjust more

wavelength-selective switches per hour, or you simply need a stable, tunable optical source, the 8160xx family

of tunable lasers offers a suitable model.

Certied quality

The 8160xx Family of Tunable Laser Sources are produced to the ISO 9001 international quality system

standard as part of Keysight’s commitment to continually increasing customer satisfaction through improved

quality control.

Specications describe the instrument’s warranted performance. They are veried at the end of a 2-meter-long

patchcord and are valid after warm-up, and for the stated output power and wavelength ranges.

Each specication is assured by thoroughly analyzing all measurement uncertainties. Supplementary

performance characteristics describe the instrument’s non-warranted typical performance.

Every instrument is delivered with a commercial certicate of calibration and a detailed test report. For further

details on specications, refer to Chapter 3 in the Keysight 8160xx Series Tunable Laser Family User’s Guide

(publication number 81606-90B01).
