The code-division multiple access (CDMA) 50-ohm matched 6-mm- square power amplifier is suitable for personal communication services, wireless local loop, and other high-bandwidth wireless data markets. The InGaP HBT amplifier module is less than half the size of comparable solutions, integrates 14 supporting components, and meets continuing requirements for small, high-capacity wireless voice and data applications. The CHP1232-PM power module is a linear-efficient three-stage power amplifier developed for PCS CDMA handsets and infrastructure systems. Features include operation as low as 3.2 V from a single positive supply, 30-dB gain at operating output power, and +28-dBm output power. The unit measures 6 mm square by 1.7 mm high.

Network media box

The network media box is a homerun enclosure that mounts over a standard electrical outlet box to distribute all residential phone and data lines to various telecommunications ports throughout the home. The Model GB33645-L1 is equipped with a telecom circuit module that provides for up to six lines in and six lines out. The module also contains an integrated RJ31X alarm intercept used in home-security applications. The Model GB33645-L2 has one telephone-company circuit module and one 4-port Category 5 data circuit module. The Model GB33645-L3 comes with two telephone-company circuit modules, allowing for up to 12 lines in and 12 lines out.

Fiber termination box

The FTP-024 24-port fiber termination box comes in singlemode and multimode configurations. Optional preconnectorized multiple fiber cable or pigtails are available for fusion splicing. Custom configurations are available.

SCSI cables

High-performance small computer systems interface (SCSI) cables are based on the 0.8-mm contact-pitch standard. These small-form-factor cables are designed for high-density computer systems and enable up to four wide 16-bit SCSI cables to plug into the back of a single PCI card. The cables use a direct- attach method, which enables the conductors of the cable to be directly attached to the PC board inside the connector.

Wireless communications cable catalog

The 16-page catalog features low-loss wireless communications cables, including coaxial antenna feeders, jumper cables, and low-inductance power cables. The publication describes WCX series coaxial cables, which have gas-injected foam polyethylene dielectrics for ultralow-loss characteristics, and the RGX series with irradiated dielectrics electrically equivalent to Teflon. The catalog contains product descriptions, specifications, and ordering information for WCX and RGX coaxial cables.

Media converters

The eoLink wavelength media converters enable bidirectional conversion of optical signals from wide-area to local-area networks and LAN to WAN. The units allow companies to use existing campus network fiber infrastructure to deliver Fast Ethernet, Gigabit Ethernet, Asynchronous Transfer Mode 155-Mbit/sec OC-3 and 622-Mbit/sec OC-12, Fiber Distributed Data Interface, and Fibre Channel. The converters can deliver wavelength conversions at speeds up to 2 Gbits/sec and to distances in excess of 40 km without a repeater.

The LX-4000 high-density open-bay frame system is suitable for crossconnect or interconnect applications. The system accommodates up to 44 units of 13/4-inch EIA standard rack space, providing capacity for more than 1,200 terminations in a single bay. This rack system combines heavy-duty steel construction, a rugged 7-ft base frame, modular fiber-management spools, front-to-rear access slots, and integrated cable-management troughs. End guards on both sides of a multiple bay system protect and conceal the cable. The base frame comes in 19- and 23-inch-wide versions. Components of the system can be ordered separately, as a prewired unit or as a Zone 4 seismic-rated welded assembly.

The N XT modular network test platform uses the Windows CE Operating System and has a built-in Type II PCMCIA slot, which supports unlimited flash memory, modem communications, and Ethernet attachment. The platform features an expandable design, which gives the user flexibility to perform a multitude of tests spanning LAN/WAN/telco through Xpand modular technology. Xpand modules plug directly into the N XT platform. The X.A.C.T. module is used for fiber-optic verification and Category 6 certification while the XAMINE module does network diagnostics and analysis. The N XT Network Test Tablet, Xpand modules, and XAMINE diagnostic analyzer are priced at $2,295, $6,600, and $1,495, respectively.

Surge protector

The Powermax 8 Tel surge protector safeguards a computer system with a modem or other telephone line. The protector's joule technology can handle an unlimited number of surges. The company guarantees that the unit will protect equipment no matter how big the surge may be. The device either absorbs and reroutes the surge energy to ground or, in the event of a catastrophic surge over 1,020 joules, the unit disconnects the power to the equipment. The surge protector has eight protect AC outlets, all spaced to accommodate transformers for maximum flexibility. Four outlets are always on and four are switched. It comes with EMI/RFI noise filtration and a diagnostic light to indicate proper grounding. The unit is priced at $34.95.

Singlemode and multimode MT-RJ fiber-optic adapters provide twice the density of SC fiber adapters, accommodating 24 duplex fiber connectors in the same amount of space occupied by 12 SC fiber ports. The MT-RJ adapter family consists of three packages: an individual adapter, an adapter in a keystone package, and a six-pack modular panel. The keystone package adapters fit into modular network patch panels and faceplates. The six-pack modular panel is used in wall- or rack-mount fiber enclosures. The devices feature a self-latching mechanism similar to that found on standard copper RJ adapters and connectors. With typical insertion loss of <0.3 dB, these adapters are suitable for fiber-optic networks and fiber-to-the-desk applications.

Surface raceway

The MediaTrak 10 nonmetallic surface raceway has three channels suitable for the simultaneous installation of both electrical and data-communications cabling. For data cabling, the unit accommodates up to 84 Category 5E cables while maintaining cable-fill requirements. The raceway features fittings that have 11/4-inch minimum bend radius. One-, two-, and three-gang boxes are available and maintain data and electrical separation. The boxes also maintain a traditional vertical orientation when the raceway is installed horizontally. The tamper-resistant unit is UL-listed for use up to 600 V.

Wire-management solution

The SL100 Series slotted duct organizes cable within communications closets and wiring panels as well as other applications. Available in gray and black, the device is made of a lightweight, rugged PVC material that meets UL flammability requirements. Side tabs, which route cable and wires out from the duct, have rounded edges to minimize abrasion. The duct and cover are flush to each other, allowing the ducts to run side by side with no gap between them. Slotted duct comes in sizes ranging from 1x1 inch to 4x5 inches.

By the Book

MMTA annual telecommunications review and forecast published

One of the most useful and targeted publications that crosses my desk each year is the MultiMedia Telecommunications Market Review and Forecast, published by the Telecommunications Industry Association and its subsidiary, MultiMedia Telecommunications Association (TIA/MMTA-Arlington, VA).

This year's volume includes a summary of technical, economic, and public-policy activities during the preceding year, followed by extensive coverage of network services (such as local-exchange services and public pay phones) and technological solutions (such as Centrex and frame relay). Separate coverage is given to mobile and wireless communications, including cellular, personal communication services, and paging and messaging. Shorter chapters also deal with collaborative technologies like videoconferencing and computer-telephone integration.

The volume concludes with a look at international markets, including North American markets other than the United States, Eastern and Western Europe, Latin America, and Asia/Pacific (with special emphasis on the Asian economic crisis and its impact on the telecommunications market).
