Optical metrology module
The Wyko optical metrology module (OMM) is designed for in-situ metrology in high-volume production environments for OEM applications. The OMM provides accurate process control metrology where it is needed most-on the production floor-featuring high-speed, non-contact topography measurements for feature heights from 0.1 nm up to 2 mm and for fields of view up to 8 mm2 on advanced surfaces. Utilizing the interferometry techniques that power Wyko optical profilers, the OMM is a standalone module designed to integrate into the user's production equipment and environment.
Veeco Metrology Group,
Santa Barbara, CA
ActiveX automation software is designed for the company's line of automatic fiber-alignment systems and workstations. The ActiveX architecture allows users to develop custom alignment algorithms using LabVIEW, C++, Visual Basic, or other Windows-based development languages. According to the company, the independence of the developing environment makes it simple to integrate nanopositioning equipment with other software-controlled systems such as adhesive dispensers, light sources, various drivers and controllers, and other ancillary equipment. The automation server contains a full set of high-level control commands for developing sophisticated positioning applications.
40-Gbit/sec error detector
The MP1776A four-channel error detector is designed for evaluating modules and devices for 40-Gbit/sec applications. The detector incorporates four 12.5-Gbit/sec error detection units, which can be used independently or together. It can measure the error rate of devices operating at 40 Gbits/sec and above when combined with a 12.5-Gbit/sec pulse pattern generator, multiplexer, and demultiplexer. Alternatively, the unit can be used to measure the error rate on four devices operating at up to 12.5 Gbits/sec each. It can also evaluate 4:1 multiplex/1:4 demultiplex communications using PRBS. The detector provides a burst measurement function that enables optical circulating loop tests.

Upgrades to the FTB-5320 and IQ-5320 multiwavelength meters have increased their dynamic range to 55 dB (from -45 to +10 dBm) to enable detection of low-power peaks on long-haul DWDM networks. The manufacturer also improved the wavelength accuracy and signal-to-noise ratio. The field-ready and manufacturing plant multiwavelength meters, which are housed inside separate modular test platforms, can be combined with other test modules, such as an optical spectrum analyzer, to fully characterize an optical network and its related components.
