Designed to preserve the properties of light passing through, the PS2300B inline optical polarization analyzer obtains real time polarization information without interrupting the optical signal. The small insertion loss and ultra-small polarization-dependent loss are suited for applications like data traffic monitoring, polarization-mode dispersion measurement, and mitigation. The analyzer is furnished as a small optical head, which can be controlled through an RS-232 computer interface with the help of user-friendly software.

For carriers commissioning and turning up new services on multiservice switching platforms, the 10-plus-Gbit/sec multirate EPX6100 transceiver with deep channelization and mixed-payload concatenations is a test module housed inside the scalable multichannel EPX platform. It can function either as a standalone to test the SONET frame section, a line, and one path (or channel) of data or as part of a set of modules to process as many as 192 paths of data simultaneously. The transceiver supports hybrid payloads and independent configuration of the payloads to simulate live traffic and enables complete testing, including bit-error rate, hybrid concatenation, and service disruption switch time. Deep channelization allows simultaneous generating and monitoring all the mapped payloads.

For high-density fiber to the X applications, the NEMA-12-rated TICE series wallmount cabinets provide increased protection from indoor contaminants, accommodate up to 144 fibers, and come in a range of sizes. Dual-hinged design ensures separation of owner/client network segments and maximizes wall space utilization for splicing and interconnection. The NEMA-4-rated MDC series wallmount or rackmount cabinets accommodate up to 216 fibers and provide flexibility to configure enclosures for single or dual access applications. Lightweight heavy-gauge aluminum-welded construction supports outside plant environments by providing protection against harsh elements. Both product series can also accommodate optical-component modules, allowing the units to house splitters, wavelength-division multiplexers, filters, and other optical components.

CODE V release 9.4's interactive 3-D viewing empowers users to create detailed renderings (solid, translucent, or wire frame) of an optical system, which can be dynamically rotated, panned, and zoomed. Within the interactive 3-D model, surface properties can be viewed and changed with a mouse click, allowing designers to efficiently modify system parameters. The ability to rapidly visualize and explore system characteristics provides a more powerful means of diagnosing design issues and visualizing complex system geometries. The program also provides closer integration with the optomechanical design process with the introduction of STEP, SAT, and enhanced IGES file export capabilities for data sharing with CAD solids modeling programs. These capabilities are particularly useful for complex optical assemblies such as off-axis systems with folded geometries, lens arrays, and densely packed systems.

For enterprise LAN as well as MAN first mile applications, four additional iConverter-managed media-converter modules include advanced fiber-to-fiber Gigabit Ethernet (GbE) to GbE (GX/X), GbE to Fast Ethernet (FE) (GX/F), FE to FE (2Fx), and 10/100 copper (UTP) to fiber (10/100VT), which features bandwidth control for easy network tuning based on need. They support 803.1Q virtual LAN (VLAN) tagging, which enables network segmentation for load-balancing and security, and 802.1p quality of service (QoS) priority, which enables prioritizing data streams based on their real time criticality. The GX/X and 2Fx utilize switch-repeater technology that can be used in network extension by cascading converters with individual segments of up to 80 km and 120 km, respectively; the GX/F can extend the life of existing network equipment; and the 10/100VT enables efficient delivery of data and IP services. Available in 850- and 1310-nm multimode fiber, 1310- and 1550-nm singlemode fiber, and 1310/1550-nm WDM-based single-fiber options, the converter modules support ST, SC, MT-RJ, and LC connectors and feature advanced remote fault detection and isolation features that facilitate remote diagnosis.

The optical multiservice metro 16–64 platform allows operators to support increasing levels of data traffic seamlessly alongside existing voice and other services. It is a high-density, full-connectivity service delivery platform as well as a compact high-capacity traffic aggregation and switching device, supporting multiple traffic types such as STM-1 through STM-64, PDH interfaces, and 10/100-Mbit/sec and Gigabit Ethernet. The highly modular platform combines multiple line rate, Ethernet transport/switching, and scalable fully nonblocking crossconnect capability. The dual data and TDM bus architecture futureproofs the platform and allows easy migration to higher-density multiple data services as demand emerges. The platform offers the new ITU-approved data-enabling capabilities—fully standardized generic framing procedure, link capacity adjustment scheme, and virtual concatenation—so carriers can offer variable bandwidth services.

For rapid deployment of high-speed communications, the free-space optics (FSO) SONAbeam E series includes two redundant high-powered lasers transmitting at 1550 nm within a simple environmentally sealed housing and transmits at distances from 50 to 4,600 m (160 ft to 2.9 mi). Interchangeable interface cards allow quick ramping of bandwidth or switching of protocols; support NxT1/E1, 10/100 Ethernet, E3/DS-3, STM-1/OC-3 protocols or data-rate transparent transmission; and provide clock data-rate recovery. Designed to withstand extreme environmental conditions, the small-form-factor system can be managed over Ethernet and is IP addressable. It is unlicensed worldwide and can be easily transported to installation sites, especially in areas that lack or have lost wireline communications infrastructure. In addition to emergency restoration of service and temporary deployments, emerging service providers can use the FSO system for aggregating the bandwidth of off-net buildings and RF networks, and mobile wireless network operators can expand their coverage or capacity.

The LightCrimp Plus singlemode connectors' new fiber-splice-engine technology allows for the precision alignment of cabled fiber to the factory-polished stubbed ferrule, enabling installers to obtain low insertion loss and low reflectance. The fiber is terminated in three easy steps: strip the fiber, cleave the fiber, and crimp the connector; termination and installation is "typically less than one minute per fiber," according to the company. The connectors exceed TIA/EIA 568 B.3 and ISO/IEC 11801 insertion loss and return loss specifications for direct termination applications at patch panels and wall outlets and for backbone or horizontal cabling. Its metal body delivers robust, stable performance over time and can withstand temperature fluctuations from –10° to +60°C. Installers can use the same toolkit for both the company's singlemode and multimode connectors.

Designed for deployment of CWDM and DWDM systems, the VAC-PAK modular rackmount attenuator enclosure allows up to 16 singlemode channels in four-channel increments to be individually attenuated from 1 to 30 dB. Attenuation adjustment is simple with a screwdriver on the front face next to each port. Patented air-gap technology provides 0.1-dB resolution over any wavelength from 1200 to 1600 nm. The slim 19-inch 1U enclosure's input and output ports are available with any standard or small-form-factor connector interface, including FC, LC, ST, MU, MT-RJ, or MTP.

"One of the most critical steps in fiber termination is scribing," notes product manager Nancy Santana-Pedersen. "If there is a mistake at this step, the contractor must cut the connector off and restart the whole termination process." With that in mind, the company's OptiSmart fiber stub connectors are designed to simplify the installation process for electrical contractors and installers, significantly reducing training and on-the-job time. The connectors terminate in any environment and require no epoxy or primer, meaning less mess and more reliable, high-quality terminations. They are available as multimode and singlemode fiber stub SC- and ST-type connectors that work with 900-µm and 3-mm-jacketed fiber in multiple applications, including terminations in fiber enclosures, workstation outlets (fiber to the desk), distribution frames, and fiber-cable and equipment terminations.
