Marketplace
Below are some of the products that sizzled on the show floor at the Society of Cable Telecommunications Engineers Cable-Tec Expo in Orlando, Fla.
Oscilloscope Family Grows
Hewlett-Packard has developed a communication mask test kit for the HP Infiniium oscilloscope family that is designed to simplify compliance testing of communication and networking products. The test kit includes mask testing software and electrical communication adapters to quickly perform American National Standards Institute, International Telecommunications Union and Institute of Electrical and Electronics Engineers industry-standard tests.
The company also has introduced new software updates to increase the performance of its oscilloscope, enhance waveform viewing and provide additional quantitative information at a glance. Updated features include new color-graded persistence to allow engineers to view signal anomalies and quickly determine how often they occur, while waveform histograms provide statistical information about the noise and jitter that occurs in a system over time.
MPEG-2/ATM Connectivity
ADC Telecommunications has introduced its AccessPoint Universal Media Access System for the transmission of multiple services over asynchronous transfer mode (ATM), synchronous optical network (SONET)/synchronous digital hierarchy (SDH) or satellite networks.
AccessPoint provides economical collection and transport of high quality, low latency video and other multimedia services for interactive applications such as broadband distance learning, videoconferencing and remote arraignment, in addition to high quality broadcast TV transport applications, according to the company. AccessPoint resides at the "edge" of a network and provides both compression and decompression of video with multiple input or output channels. Standards-based MPEG-2 is used to provide scalable bit rates to 15 Mbps (4:2:0) and 50 Mbps (4:2:2) using I-frame, IB-frame or IPB-frame coding with flexible GOP structures.
Indoor Amplifier
Quality RF Services has announced the new 860 MHz QDAX power-doubled and quadra-powered indoor amplifier line.
The new line features 5 to 40 MHz active return path and 50 to 860 MHz forward bandwidth. The company says the plug-in interstage fixed equalizers provide optimum RF frequency response.
The use of plug-in pads in 1 dB steps helps to provide precise level control.
Fiber Splice Closures
Tyton Hellermann has introduced a line of fiber-optic splice enclosures for protection in aerial, underground and pedestal applications.
According to the company, CableTyte closures are compact and work with a variety of fiber counts; theyre designed for installation and re-entry without special tools. The products non-heat-shrink sealing system provides a watertight seal without a torch. Heat-shrink sealing also is available.
Closures include an optional curved splice tray. Other closure styles and tray options also are available for low and high fiber counts. Accessories include mounting brackets and hardware for stability, a port cutting tool, shield bonding products and fiber splice protectors.
Coring/Stripping Tool
Ripleys all-in-one tool will strip the jacket, core out the dielectric, and strip and bevel the aluminum sheath. The new design attaches the jacket stripper body to the main body of the coring and stripping tool by means of a quick-change rotating ring.
Plant Management System
AM Communications has released its QuickStat Plant Management System, a plant management solution for small- to medium-sized hybrid fiber/coax (HFC) network operations.
The QuickStat System is packaged in a single personal computer (PC) client/server station. The station is preconfigured with AMs OmniVu software package, OmniComm cable system interface card and the QuickTest probe.
The QuickStat System can support up to 99 transponders. QuickStat supports AMs entire family of transponders, including power supply monitors, fiber node monitors, amplifier monitors, as well as AM end-of-line (EOL) monitors.
QuickStat enables operators to improve their overall responsiveness. It notifies the user of network problems such as fluctuating RF signal levels or power levels, pinpointing the problem areas location within the plant, and will keep automatic maintenance records in its Omni database. The system also features a graphical user interface (GUI).
Times Fiber Adds New Reels
Times Fiber Communications has added 100-percent recyclable reels to its line of semi-flex trunk and distribution cable products.
Designed for strength and environmental longevity, these reels are designed to assist operators in minimizing dollars spent on waste management with added cable protection and custom-designed recycling programs.
Gateway Development
The Amecom division of Litton Industries will continue working with MacroDyne Power to produce a residential gateway for hybrid fiber/coax (HFC) networks.
The companies recently completed a six-month feasibility analysis, and the product, now in prototype phase, will allow cable operators the ability to offer single or multiple services by simply inserting a module into a host controller located at the side of the subscribers home.
