The "rate-limiting" TC3220 10/100-Mbit/sec two-port fiber-optic Ethernet media converter enables service providers to control or limit bandwidth to its customers in increments of 64 kbits/sec. Power redundancy is standard, with options including a two-way "one-fiber" version to maximize fiber plant usage and an industrial-hardened version for extreme environments of –40° to +80°C. The converter offers 152 incremental settings for 10 Mbits/sec and 226 settings for 100 Mbits/sec. Rate-limiting can be applied on a per-port basis or input/output traffic. Also included is a built-in Ethernet switch that enables distances up to 100 km without additional hardware (e.g., switch or router). The converter provides 10/100-Mbit/sec auto-negotiation and automatically adapts to full- or half-duplex mode. Transparent to the network, it operates effectively even during high-demand traffic loads. It comes standard in a modular standalone/card version that fits into a 10-card rack assembly.

For long-haul and metro DWDM optical-networking systems that deploy optical add/drop nodes and varying link budgets, the PGE60850 variable gain amplifier (VGA) provides flat response across a wide gain range of 15 dB. It features high optical power output of ±20 dBm, ensuring compatibility with systems having different link losses. For easy integration, the VGA has mid-stage access and supports up to 12 dB of mid-stage loss for dispersion compensation modules, optical add/drop multiplexers, and other high-loss optical components. It has excellent low noise and low ripple to enable efficient allocation of link budget. On-board electronics provide transient control that enables wavelength versatility and dynamic provisioning throughout the network. The VGA allows adding and dropping of more than 95% of channels with no impact on system performance.

Available with Windows 2000 capability, the FiberLine high-precision programmable optical CMM system measures critical dimensions on small parts in the manufacture of multifiber terminators, V-grooves, ferrules, optical disks, image sensors, and other optoelectronics devices. Such critical measurements include wafer linewidths, component positioning, and optical-fiber alignment with feature sizes as small as 0.5-µm. The system provides field of view measurement accuracy to 0.01 µm (10 nm) and point-to-point X-,Y-, and Z-axis measurement repeatability to 0.01 µm (10 nm) at 1 sigma (with 100X objective). Application programs are written using powerful text-based Measurement Control Language. Program files are easy to read and allow users to modify existing programs or create their own programs to control the system's operation. The XYZ positioning components and system structural components are manufactured from cast iron and granite for the greatest possible accuracy and precision.
