General Information
This user’s manual for the Swept Wavelength System (SWS) contains complete operating
instructions for using the SWS15100 and SWS16100 systems. For information on using the
tunable laser source as a stand-alone unit, see the
SWS15101 and SWS16101 Tunable Laser
Source User’s Manual (document SD000319). For information on the polarization controller, see
the SWS15104 Four-State Polarization Controller User’s Manual (document SD000327).
Wavelength division multiplexing (WDM), and especially dense WDM (DWDM), has become a
key solution to the ever-increasing demand for network capacity and flexibility. Network device
characteristics vary with wavelength; therefore, WDM systems are forcing the wavelength
characterization of all components used in the system. Accurate characterization of the
wavelength-dependence of a device previously required many time-consuming measurements.
For example, in the past, characterization of a device over a range of 30 nm, with 0.1 nm
resolution, required 300 measurements and took three or four hours to complete.
The Swept Wavelength System determines wavelength characteristics of devices used in
optical networks. The SWS tests passive optical components for performance. The SWS can
be used to test devices under operating conditions to maximize the efficiency of components.
The system is available in two versions that have similar hardware components, cabling
requirements, and operating procedures, but differ in the following specifications:
•
Model SWS15100—C-band, 1520 to 1570 nm, completes a 50-nm scan with 0.003 nm
resolution in six seconds, plus one and a half seconds per channel, using the parallel port
interface
•
Model SWS16100—L-band, 1540 to 1630 nm, completes a 90-nm scan with 0.003 nm
resolution in eight seconds, plus three seconds per channel, using the parallel port interface
Devices that can be characterized by the SWS include:
•
Attenuators
•
Bandpass filters
•
Broadband couplers and splitters
•
DWDM demultiplexers
•
Fiber Bragg gratings
•
Isolators
•
Switches
•
Interleavers
