Phoenix Photonics, manufacturer of all-fibre optical components and modules, has introduced an inline power monitor to its product range. The noninvasive power monitor is a small-footprint device designed to replace a tap coupler—a photodiode with a single small-footprint package. The device is based on interaction with the evanescent field of the propagating signal and consequently is noninvasive to the optical path. It offers low insertion loss with high responsivity. Several standard models are available to accommodate power-range requirements in different applications. A single device will operate from 1280 to 1630 nm. The monitor is housed in a compact 10×5mm diameter package. Among other applications it is designed for EDFA gain modules, DWDM channel power balancing, power control, and optical-channel monitoring.

Krell Technologies introduced its Icon system, which integrates optical-connector polishing with inspection in a multistage platform. Icon fully automates connector processing from air polish through final finishing and quality testing. Inline inspection includes surface defect analysis and interferometric measurements. Icon utilises connector workholders that incorporate an independent suspension design for uniform polishing with vastly extended film life. Waveguides, arrays, ferrules, and other components are also supported by the Icon system.

Polytec introduced the MMA-300, describing it as the world's first integrated laser Doppler vibrometry and stroboscopic video microscopy system for full-field 3-D characterization of MEMS dynamics. The MMA-300 combines the MSV-300 scanning laser vibrometer with the new PMA-300 planar motion analyser. It maps out-of-plane vibration while PMA-300 measures in-plane motion simultaneously. The analyser exploits the advantages of both techniques: the extreme accuracy, speed, and broad application of laser Doppler together with video microscopy's ability to measure in-plane motion of virtually any surface.

MSV-300 offers a measurement frequency range from near-DC to 30 MHz, including FFT and time domain processing. Whole-field vibration response is animated for specific frequencies or in the time domain. A laser vibrometer measures any vibration waveform in real time, including transient and random.

Applications include modal analysis, impulse response, settling times, resonant frequencies, Q-factors, calibration, FE model verification and reliability of MEMS, telecoms arrays, gyroscopes, and other "micromachines."

Alfautomazione expanded its product offering for the optoelectronics industry with the launch of its AlFiber3000 fibre-optic alignment system. The system is configurable for fibre-device, multifibre-device, and mulitfibre-device-multifibre processes, providing automatic control of the alignment process and flexibility to implement custom alignment routines. Imaging, motion control, and data acquisition are fully integrated into the system, which has a scan rate of 300 points/sec during alignment. The vision system of the AlFiber3000 allows for coarse alignment resolution of up to 5 mm controlled by imaging and allows shorter cycle times and higher setup flexibility. Alfautomazione's optical power tracking algorithm enables a rapid multi-axis alignment process. The AlFiber3000 supports automatic loading and unloading of components. Glue dispensing and UV curing as well as laser welding are available as options.

Limo is presenting its complete range of micro-optics for collimation, beam-shaping, and fibre-coupling for industrial high-power diode lasers at the forthcoming Laser 2003 Expo in Munich. The significant advantages of diode lasers can be widely deployed by using LIMO's optics in industrial applications. The collimation optics also benefit the beam-shaping of excimer lasers. Thus, LIMO is offering new homogenisation optics for lithography, material processing and medicine. LIMO's new M3 optics will be presented in Europe. They are already the basis for optical communications technologies for next generations of passive and active modulators, switches, and amplifiers.

For the first time, a "highest brightness" laser with 25 W at the output of a 100-µm fibre will be introduced. The offer of lasers with high power now also includes passively cooled lasers with output power up to 120 W.

Communication By Light (CBL) launched its scalable FiberMultiplier family. Highlights of the range are coarse wavelength-division multiplexer with four and eight channels. Up to eight independent channels can transmit different signals simultaneously over a single fibre pair. With its modular design the FiberMultiplier can be customised. Management occurs via the Web or simple network management protocol agent.

FiberMultipliers offer a range of parameters and diagnostic functions as well as monitoring the power level of incoming signals during operation. With interface adaptation of once-purchased modules as well as software and firmware upgrades, CBL offers its customers high investment protection. The FiberMultiplier transmits applications in wavelength ranges between 1470 and 1610 nm over one pair of fiber. Each single channel can transmit a maximum data rate of 1,250 Mbits/sec over distances up to 30 km.

Laurel Networks introduced 10-Gbit/sec SONET/SDH and Gigabit Ethernet (GbE) physical interface (PHY) cards for its ST200 Service Edge Router. With the interface, the ST200 delivers the highest density and widest range of interfaces (64 kbits/sec to OC-192) and most diverse multiservice support available, the company claims. The one-port OC-192c/STM-64 SONET/SDH PHY card scales to eight ports per ST200 (16 per telco rack) and supports packet over SONET, point-to-point protocol, high-level data link control, and frame relay encapsulations. The one-port 10-GbE PHY card scales to eight ports per system (16 per telco rack) and supports advanced Ethernet over MPLS capabilities, including 802.1Q VLANs and 802.1p prioritisation.

BASIK is a new compact diode pumped DFB fibre laser module from Koheras. The laser offers 100-200-mW single longitudinal output (CW), a linewidth less than 1 kHz, and low phase noise. Measuring 43×117×75 mm), the module is fitted with a LEMO input interface and 3-mm jacketed singlemode output fibre (optionally polarisation-maintaining). Laser wavelength is adjustable and can be set to 0.1-pm long-term accuracy. The lasers are produced for operation within the wavelength ranges 1030-1090 and 1535-1570 nm and can optionally be supplied as fast-tuning devices (>20 kHz). The module has been designed as a new enabling integrated source to meet the demands of several sensor applications such as LIDAR, security, and oil field sensing.

Two new models have been added to Agilent's N4900 serial bit-error-ratio (BER) test series. The instruments are claimed to be the industry's first to provide built-in differential inputs/outputs, clock data recovery (CDR), and enhanced jitter, analysis, and measurement capabilities to enable R&D, design verification, and manufacturing engineers to perform full parametric measurements across a wide range of technologies and applications. The new testers cover frequency ranges of 150 Mbits/sec-13.5 Gbits/sec (N4901A) or 150 Mbits/sec-7 Gbits/sec (N4902A).

The N4900 test series can be used for design verification and characterisation of components, semiconductor chips, and modules as well as general-purpose applications in R&D and manufacturing.

Omnitron Systems Technology added a new module to its iConverter managed media-converter product family. The iConverter GX/T provides 10/100/1000Base-T UTP to 1000Base-X (fibre) media and speed conversion. It extends high-speed network distances up to 80 km with advanced Gigabit Ethernet fibre-optic technologies. The iConverter GX/T models are available to support multimode, singlemode, and single-fibre options. They support SC, MT-RJ, and LC connectors. The UTP port supports 10/100/1,000-Mbit/sec speeds and half- or full-duplex auto-negotiation with hardware and software manual override controls to set the desired speed and duplex mode. The GX/T features user-selectable link propagate, link segment and remote fault detection modes that facilitate quick fault detection, isolation, and reporting and increase network uptime and reliability. It can be used in a managed or an unmanaged configuration.

Femto's lock-in amplifier boards are designed for industrial OEM applications as well as precise scientific measurements. These "research grade" amplifiers are versatile and suited to signal recovery applications. Four different models are available, from the single-phase to the 120-kHz dual-phase model, with an integrated real time vector summing amplifier. Sensitivity settings, time constant, and phase shift can be selected in real time using a remote control interface or by external switches provided. 19-inch boards can operate in EMI-designed standard cases and are the perfect choice for designing high-performance multichannel systems, expanding the reach of lock-in amplifiers into cost-sensitive applications.

Cypress Semiconductor has announced volume production of its field-programmable zero delay buffer (CY23FP12), a 200-MHz clock distribution device featuring a flexible architecture that can be customised to fit a wide range of applications. The single chip, which incorporates the functionality of an entire clock distribution portfolio, is implemented on Cypress's proprietary silicon oxide nitride oxide silicon (SONOS) technology and is fully programmable via manufacturing facility or desktop programmers. The buffer enables the user to define an application-specific clock distribution device with up to 12 outputs, customised input and output dividers, feedback topology (internal/external), output inversions for differential operation, and output drive strengths as well as a variety of other functional and performance characteristics. For additional flexibility, the user can mix and match multiple functions. This feature enables implementation of a number of distinct configurations, all of which are selectable via control bits on a single programmed device. Cypress's buffers also feature a proprietary circuit that shuts down the device in case of a reference clock source failure, thereby simplifying power-down schemes.

PMC-Sierra has introduced two intelligent Fibre Channel (FC) port bypass controllers designed for networked storage systems. The PM8368 PBC 18x2G and PM8372 PBC 4x2G controllers deliver extensive system diagnostics, design flexibility, high port density, and low power demand. Leveraging PMC's high-speed mixed-signal crossconnect and 2G FC expertise, this new class of product enables storage-system OEMs to develop low-cost, high-performance, and intelligent storage subsystems using fewer components. IT managers needing to maintain complex multivendor and mission-critical storage networks will benefit from the enhanced system-level diagnostics and increased reliability provided by PMC's standards-compliant carrier class 2G FC products.
