These flange-mount fiber-optic links are for 70- or 140-MHz intermediate frequency 2-km applications and can be used in a variety of satellite signal applications. The links are available for less than $1000. Ortel Corp. Alhambra, CA
COMPONENTSThe DSC-R40X photoreceivers have bandwidth of up to 14 GHz, voltage gains up to 1000 V/W, single- and dual-bias voltage models, power gains up to 30 dB, and pigtailed backreflection lower than 55 dB. Typical optical terminations for the devices are FC/PC or APC, but other fiber terminations can be supplied to customer specifications. RF output is via Wiltron Type K connectors, which are compatible with SMA style. Discovery Semiconductors Inc. Cranbury, NJ
The BelOptix Series cables are designed to be futureproof and environmentally protected. The cables contain LCF laser-certified fiber to handle the new light sources required in short-wavelength Gigabit Ethernet systems. They are operational with current LED light sources and exceed FDDI+ performance specifications. The cables are produced with RiteStrip II, a micron-buffered fiber-coating process. The process is designed to strip to 250 microns or down to 125 microns. A gel-less water-blocking system is also included. Belden Wire & Cable Co. Richmond, IN
The SLW-180 SELFOC Microlens is designed to redirect large-diameter, large-NA optical beams by minimizing longitudinal spherical aberration over 80% of the lens's diameter. The lens is currently used in optical isolators and DWDM devices. NSG America Inc. Irvine, CA
TEST EQUIPMENT
The Advanced Fiber Ranger uses a 1310-nm laser for short- to immediate-range applications. The dead zone is less than 30 m and its maximum range is beyond 20 km. It features simplified controls that require no special training. It can detect up to seven events in less than 15 sec from a cold start-up. The device enables the user to select the index of refraction so that accurate measurements can be obtained from different cable indices without additional calculations by the operator. Readings can be reported in feet or meters and are stored so one to seven reflections can be reviewed repeatedly until the next measurement is made. Designed specifically for field installation and service, the handheld fault locator is offered at $2495. Wilcom Inc. Laconia, NH
INSTALLATION
The Fiber-Net modular fiber panel is 3U 19-inches rack mounted (185 mm in depth). It allows for up to 12 cassettes to be accommodated for expansion of fiber-optic networks using new cables. The cassettes can be used to terminate individual cables or accommodate optical components such as WDMs, splitters, switches, bare fiber for link extension, and OTDR dead zone coverage. Users do not have to choose different types of cassettes according to the operating wavelength, since both 1310- and 1550-nm wavelength units will operate with 0.4-dB insertion loss and 40- to 50-dB isolation to 1625 nm. All fibers are terminated with SC/APC connectors and adapters or others, such as FC/PC, SC, E2000, DIN, or SCII. Optronics EYT Athens, Greece
The 116 FR is a 1:1 mix ratio epoxy potting and casting compound designed for production use. The mixing ratio is intended to make the epoxy suitable for production line mixing as well as automatic dispensing. According to the manufacturer, it is one of the safest epoxy compounds available, as it reduces the risk of eye, skin, or respiratory problems usually associated with epoxy compound use. Applications include casting sensitive electronic components and potting telecommunications equipment. It is available in 2-quart, 2-gallon, or 55-gallon kits. Insulcast Roseland, NJ
