The standard 86105D (86115D) plug-in module

is typically used for testing multimode and

single-mode optical signals at rates from 8 to

14 Gb/s. The new option 281 (282) uses state-

of-the-art high-speed photodetector technology

and improved sampler electronics to provide

true measurement hardware bandwidth

capable of reference receiver performance

to rates as high as 28.05 Gb/s. No pattern

length restrictions are imposed, and no signal

processing is required. The companion electri-

cal channel bandwidth has been improved to

exceed 50 GHz bandwidth. The 86105D-281

(86115D option 282) is compatible with

both 86100C and 86100D mainframes (using

firmware 10.0 or higher for the 86100C and

firmware 2.0 or higher for the 86100D).

Keysight 86100D DCA-X:

The industry standard for

optical communications

waveform analysis

Keysight Technologies, Inc.’s Digital

Communications Analyzers have provided opti-

cal communications engineers with the most

accurate and easy-to-use tool to characterize

their waveform performance. The modular

platform has allowed the 86100 system to be

reconfigured and upgraded as communications

technology has evolved. The 86105D has a wide

bandwidth optical channel and electrical chan-

nel. A multiple optical channel system can be

created with the 86115D. The 86115D has two

optical channels similar to those available with

the 86105D and no electrical channels.

Reference receivers 14.025, 25.78, 27.95, 28.05 Gb/s

(With option IRC, reference receivers can be

defined at arbitrary rates between < 8 and

> 40 Gb/s, pattern lengths restricted to PRBS16

and shorter. IRC is not required for standard

rates from 14.025 to 28.05 Gb/s). 14.025 Gb/s

reference receiver is optional. A general purpose

15 Gb/s filter is included at no charge when the

14.025 Gb/s optional filter is not selected.
