SWS15100/16100 Swept Wavelength Systems Applications The swept wavelength system is the solution for characterizing the wavelength dependence of passive optical components. The SWS is available in two wavelength ranges: the SWS15100 system scans the Cband from 1520-1570 nm and the SWS16100 offers extended L-band coverage from 1541-1630 nm. Both systems provide a very high wavelength accuracy of ± 3 pm (± 0.003 nm) and a speed considerably faster than a broadband source/OSA or a tunable laser source/power meter system. The SWS can completely characterize the insertion loss of a 40-channel DWDM in less than 90 seconds. Where full coverage of the C and L-bands in a single trace is desired, the signals from the transmitters can be combined with an optional dual band selector switch located in the receiver. The standard SWS package consists of; a tunable laser source and source optics module in a transmitter cabinet, receiver chassis, a parallel port connector or optional data acquisition board, application software, and a user-supplied computer. The tunable laser provides a narrow line width source in the wavelength range of interest. The source optics module performs real-time wavelength measurements and transmits them to the receiver. At the receiver, a portion of the light is sent to a reference detector while the rest is sent to the device under test (DUT). This process provides an accurate ratio measurement. One of the essential benefits of the SWS is the ability to simultaneously test multiple outputs of a component. As the number of
outputs increases, the test time per component decreases significantly compared to more conventional measurement techniques. Each receiver comes standard with one control module and a dual detector module. With additional chassis and detector modules, up to 128 channels can be tested simultaneously. A single transmitter unit can support nominally four independent receiver stations. As the SWS is a modular system with a distributed architecture, only a single optical fiber is needed to connect the transmitter to each receiver.

Swept Wavelength System Components PDL Controller (optional) The SWS15104 four-state polarization controller allows for the PDL and average loss to be measured quickly as a function of wavelength. The Mueller matrix method is used, whereby PDL is determined by measuring the IL of the input light for four specific polarization states. The four states consist of three linear polarizations at 0, 90, and - 45°, and one circular polarization of the input light. The controller takes one IL measurement at each of the four polarization states, then the SWS software calculates PDL using this input. The measurable PDL range is 0-5 dB.
SWS Software w ith 16-Channel Demux
Version 3.0 Software (standard with system) The latest version of the software introduces considerable upgrades in terms of program usability, flexibility, and robustness. The software is designed to work seamlessly with the dual band selector switch (optional) for combining C and L-band traces, and is backward-compatible with the data acquired with earlier software versions. File handling and data presentation tools are flexible. Analytical tools enable the user to specify bandwidth, passband, crosstalk, and flatness parameters for up to 128 channels simultaneously.
Compact Receiver
If custom applications are required, the software is packaged with welldocumented dynamic link libraries (DLLs) that integrate with your LabVIEW, C/C++, or Visual Basic application.
Interface Options The SWS receiver is delivered with a parallel printer port interface to connect with the user's computer. As an option, a fast parallel port interface with a National Instruments data acquisition card is available.
Compact Receiver (optional) To save cost and space on your desktop, a smaller version of the receiver is available. The compact receiver has two detector channels built into a mini-chassis.
User Manual The user manual is supplied with the software on CD-ROM and as a hard copy.
