Video and PZT system
The pure digital Fiberlink 3800 series system for video and PZT (pan/zoom/tilt) control provides all digital processing and transmission of one-way analog video and two-way data over one or two fibers. The system's video channel is compatible with all common closed-circuit TV cameras and monitors utilizing NTSC, PAL, or SECAM standards. Data protocol can be different or the same on the transmitting and receiving ends. The series is available in singlemode and multimode versions.

COMPONENTSOC-768 modulator driverThe S76803 is an OC-768 silicon germanium modulator driver that operates at speeds of up to 48 Gbits/sec and is suited for use in short-reach and long-reach SONET-based fiber-optic data-link applications within the MAN and WAN marketplace. Designed for use in electro-absorption modulators and differential lithium niobate modulators, the product offers a 3.5-V and 7-V output swing. The S76803 features a 50-ohm input amplifier with a DC cancel circuit allowing for direct coupling to the input signal.Applied Micro Circuits Corp.,San Diego
Pump lasers
This series of multimode semiconductor pump lasers delivers up to 2.5 W of power and is available at 915 nm for pumping Raman fiber lasers and at 975 nm for co-doped EDFA pumping. The series of lasers is offered in a wide variety of standard and custom configurations to simplify their integration. Standard packages include chips on submount and lensed chips on submount as well as hermetically sealed fiber-coupled, industry-standard, 14-pin butterfly packages. Thermoelectrically cooled and uncooled versions are available.

Automation software
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.

Multiwavelength meters
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.
