Suppression components/ systems line
Assisted by 3-D computer-aided design (CAD) software, Americor's line of electromagnetic interference/radio frequency interference (EMI/RFI) suppression components for systems makes designs ready to be incorporated into customer products and drawings. The system combines RFI components with other components such as switches, terminal blocks, relays, and power cords into one unit to maximize the design and minimize installation labor. Packaged in custom-designed and compact housings, the suppression systems arrive ready for installation. Custom-designed components with snap-in mounting eliminate the need for lead-wires.

Power meter, laser and LED source
The Model 510 optical power meter by Cercis is offered with a choice of three different detectors-3 mm germanium for 750 to 1,500 nm; 2 mm indium gallium arsenide (InGaAs) for 850 to 1,650 nm; and 3.5 mm silicon for 400 to 1,100 nm. Available in single- or dual-source versions, the Model 520 laser light source operates at -10 dBm, and its features are accessed via three keys. These three keys provide the functions for the Model 530 light-emitting diode (LED) source, and red or green LEDs illuminate at power on, source on, and modulation. All instruments are powered with either an internal 9-V battery or optional alternating current (AC) adaptor.
NORDX/CDT's GigaBIX data transmission crossconnect system has a channel bandwidth of up to 300 MHz, and offers a data rate of 4.8 Gbits/sec, according to company claims. The system's termination kits contain components required to terminate 4-pair or 25-pair cables in a crossconnect system; a base and mount designed to accommodate 4800LX cables; 12 clear graphite 6-port connectors; black designation strips and wire guards; white labels; wood screws; Velcro ties; and a detailed installation guide. A cable management module, patch cord organizer, horizontal channel plates, and a management ring assist in vertical and horizontal management. Available in various lengths for design flexibility, the system's plug-and-go patch cords claim to offer performance up to 300 MHz in the IBDN System 4800LX. Wires contain fluorinated ethylene propylene (FEP) for improved transmission and fire rating compliance, and pairs have been stranded for cable stability.
POINTE CLAIRE, P.Q., CANADA
Tabs on Erico's durable Caddy AFAB Series angle brackets expedite assembly and stabilize the J-hooks-eliminating any movement of the hook after installation. Designed for modular installations, two brackets can be linked together with two J-hooks and installed on a threaded rod to create a tree assembly for multiple runs of high-performance cable. These brackets are available with different mounting hole sizes including: the standard quarter-inch; 3/16-inch for powder-actuated tools; and one that can accommodate 3/8-inch and 10-mm threaded rod or bolt. Two brackets may be assembled in a 90° angle to guide cable around a corner and still maintain the necessary bend radius, the company says.
Cable management rod
The quarter-inch-diameter Push-Pull Rods by CMD are made of non-magnetic fiberglass and are polypropylene-coated to avoid shattering. These rods are used for running and retrieving cable, and you can use them to push or pull cable inside or outside conduit. Each rod is five feet long with threaded attachments at each end, and is flexible enough to go around corners and up and down walls. You may connect as few or as many rods together to create your desired length.

Flexible and scalable, Canoga Perkins' UCS 1001 accommodates optical transponders and repeaters, wavelength-division multiplexing (WDM), 10/100/1,000 Ethernet, and E1/T1 and E3/T3 modems into one system. Modules inserted into this two-slot chassis are replaceable, and they will not interrupt another module's operation. The chassis backplane is the communication conduit between the modules, and in full-redundancy, the troubled module is replaceable without interrupting the others' operation. The backup or redundant link/module is monitored for operational status by the active module.
Cable and conduit labels
VIP Division's line of self-adhesive labels for wires, cable, and conduit are screen-printed on plastic and supplied with an adhesive for residential, commercial, and industrial applications. The labels are available in three sizes: .5x2, 1.75x3, and 3x6 inches. Caution labels are printed black-on-orange with legends. Danger labels are printed white-on-red, with legends that read "danger" or combination voltages. Labels may be custom-manufactured in your choice of size, color, and legends.
Designed to provide PBS systems, computer racks, and other equipment with protection from theft and vandalism, Bryce Fastener's Uniqz provides the benefits of a combination lock in the head of a screw. It features a three-sided, recessed head design that is custom-fabricated and licensed to individual users. Each side of the head has the potential for 20 different degrees of angle and depths of recess. With a specialized screwdriver bit, fasteners can have a 12-digit combination code. To use this feature, insert the key into the head of the screw and twist it until the combination matches and falls into place.

Underwriters Laboratories Inc. (UL-Chicago) 497-listed, ITW Linx's Cat5-Lan 4-pair surge protectors provide solid-state protection with 110-connectors in a 4-pair module for local area network (LAN) circuits. According to company claims, a response time of 2 to 5 ns prevents transient voltage from damaging electronic equipment by diverting the voltage to the ground via the grounding screw on the side of the module. Each protector includes: 110-connectors, a PC board with punch-down color-code, a shield grounding clip for 4-pair OSP cable, a grounding screw, and mounting hardware. An Isolated Loop Protector provides further protection in hostile industrial environments and for unshielded twisted-pair (UTP) cables within buildings per UL 497B.
Also Underwriters Laboratories Inc. (UL-Chicago) 497-listed and featuring an Isolated Loop Protector, the ML25-Cat5-Lan 25-pair surge protector fits the footprint of a 66 Block. It snap-fits to standard 89D brackets. With single-pair protection, the 25-pair surge protector scales the protection to the system size, protecting only the lines requiring protection. Solid-state protection resets without user intervention.

MaxCell, a flexible fabric conduit engineered by TVC Communications, lets you install three cables in a two-inch conduit or nine cables in a four-inch conduit. The engineered fabric has a low co-efficient of friction and does not spiral like conventional innerduct, resulting in low cable pulling tension. This fabric does not rip or tear during entry and re-entry, letting you add to occupied conduits with existing cable. Also, the fabric is chemical-resistant to ground chemicals and petroleum products, as well as water-repellant. Color-coding by printing and stitching identifies each cell.
By the Book
Textbooks introduce basic engineering systems
Artech House Publishers (Boston, MA) has produced a new Introduction to Infrared and Electro-Optical Systems, by Ronald G. Driggers, Paul Cox, and Timothy Edwards. With a 1999 copyright, the 407-page illustrated hardcover is a volume in the Artech House Optoelectronics Library, aimed at engineering professionals and students. Following introductory chapters on the mathematics of the subject, the book covers diffraction, sources of radiation, atmospherics, optics, resolution, detectors and scanners, electronics, and displays. The final section, on systems, covers both infrared and electro-optical systems, with a final chapter on considerations for sensor design.
The Wiley Series in Telecommunications and Signal Processing, from technical and engineering publisher John Wiley and Sons (New York, NY), includes the Second Edition of Optical Communications (copyright 1995), by Robert M. Gagliardi and Serman Karp. The 347-page hardcover volume is, again, heavily mathematical and is oriented toward engineers. Topics covered include the optical communication system, optical field reception, photodetection, and both noncoherent (or direct) and coherent (or heterodyne) detection. Later chapters deal with optical digital communications, fiber-optic communications, fiber networks, the atmospheric optical channel, and issues in outer-space optics.
