The “Dispensing Components QC Checklist” delivers 15 simple checks to help users of air-powered and mechanical fluid dispensers achieve better process control, reduce waste, and increase productivity. The complimentary booklet features numerous photos, step-by-step instructions, and hints on what to look for when evaluating components from various suppliers.

EFD Inc.,

The Optical Communication Design Suite version 4.6 includes OptSim and the multimode add-on ModeSYS. A new bit-error ratio estimation technique handles noise statistics based on Karhunen-Loève series expansion for optical signal and noise, which offers higher accuracy for systems in which signal-noise beating and nonlinear phase noise are dominant, such as in a DPSK system with direct-detection balanced receivers. The software is capable of performing electronic dispersion compensation modeling with feedforward equalization. The design suite also supports applications such as 40-Gbit/sec systems, RF photonics, FTTX PON, and high-power optical amplifiers.

Extension platform for storage area networks
The BroadGate SAN XT enables disaster recovery and business continuity for hundreds of kilometers, at a throughput up to 2.5 Gbits/sec for high-end storage applications, over DWDM networks, SDH/SONET infrastructures, dark fiber, or independently without an existing network. The extension platform integrates with the XDM multiservice provisioning platform (MSPP) family and is supported by the LightSoft network management system. The compact device can multiplex several SAN streams into a 2.5-Gbit/sec optical aggregate and is interoperable with any standard vendor’s server, using international standards.

ECI Telecom, www.ecitele.comTh 211948

The Optiva fiber-optic transmission platform features customizable multioriented video, audio, and data input configuration; daisy-chained time-division multiplexing; intelligent bandwidth allocation (up to 2.5 Gbits/sec); and an upgrade path to support protocols from composite video to uncompressed HD-SDI and from analog audio to digital AES/EBU. All systems comply with CE standards, UL safety standards, and the FCC Part 15 regulations for emissions control.


The Xgen6000 is a Gigabit Ethernet optical network terminal (ONT) designed to operate on an ITU-standard PON and support redundant fiber feeds while economically providing SONET reliability. The ONT extends the family of Extended Gigabit Ethernet Node (Xgen) products, which are targeted for high-density, high-reliability applications and are able to be curb- or premises-mounted.

Miniature CWDM components and subsystems
A line of miniature CWDM components, as well as a range of line cards, splice cassettes, and 19-inch rack-mountable modules, is suitable for outside-plant applications such as metro edge networks. Operating endurance has been demonstrated from -40° to +85°C along with associated temperature cycling, storage, humidity, shock, vibration, and cable-retention testing, in accordance with Telcordia GR1221 for Uncontrolled Environment. Modules are available in four- and eight-channel versions and address the entire band of 18 specified ITU wavelengths. Insertion loss for an eight-channel module is typically 1.6 dB, with corresponding link loss values less than 2.9 dB.

Offering an extended operating temperature range from -40° to +85°C, the NP2000-XT erbium-doped fiber amplifier (EDFA) operates beyond Telecordia requirements, making it suitable for demanding FTTH applications. The EDFA provides output power greater than 18 dBm across the C-band, and typical electrical power consumption is less than 5 W. The module measures 150×80×20 mm.

Nuphoton Technologies Inc.,

The MiRIC series of miniaturized Fast Ethernet over PDH and SDH/SONET connectivity devices implement the Smart SFP design, which allows the device, housed in a standard SFP package, to support LAN bridging, OAM, VLAN tagging, flow control, and a variety of protocols (GFP, HDLC, CHDLC) over E1/T1 or E3/T3. It weighs only 30 g and is 1 cubic inch in size. The MiRIC can be plugged directly into an Ethernet device, eliminating external units, cables, and power supply cords because it draws power from the host device.

RAD Data Communications,

Proprietary fiber Bragg grating (FBG) technology enables the integration of the 1901FBF PowerBragg supervisory channel filter into the singlemode fibers connecting subscribers to an FTTH network. Remote, real-time monitoring of performance, connectivity, and reliability allows faster network recovery and restoration of services.

Low-power grooming switches
The VSC9190 50-Gbit/sec and VSC9191 100-Gbit/sec time slot interchange (TSI) grooming switches incorporate automatic protection switching and rate aggregation into a single unit to reduce board chip count by a factor of five. The switches perform deskewing, switching, and SONET/SDH signal regeneration at the STS-1/STM-0 level within access/metro equipment such as SONET/SDH multiservice switches, add/drop multiplexers, and optical switches, in addition to DWDM long-haul and metro equipment. The scalable switches use bit-slicing to enable configurations up to 1.36 Tbits/sec using the lowest possible chip count for routing traffic to and from scalable hubs.

Vitesse Semiconductor Corp., www.vitesse.comTh 211951

The Redhawk, a two-port 10-Gbit/sec intelligent media access controller (MAC), incorporates embedded XFI SerDes and multiprotocol congestion management technology. The MAC is integrated on an evaluation platform with a dual-port card that can be used as a full-rate, one- or two-port 10-Gbit/sec Ethernet system, or a dual-port oversubscribed system with statistical multiplexing. Two controllers can be cascaded with the platform to provide a four-port oversubscribed 10-Gigabit Ethernet system. Customers can evaluate network side XFP, XENPAK, and X2 optics, as well as XAUI and SPI-4.2 system side interfaces, using a standard PCI or USB interface for control.
