Its overall length is less than a jacketed LC connector, allowing for ample door clearance.Molex, Lisle, IL, www.molex.com

For IEEE 802.3ae stressed receiver conformance testing at 10-Gbit/sec wavelengths, the Optical Standards Testers (OSTs) are now available at 850 and 1310 nm in addition to the previously supported 1550-nm wavelength. Factory-calibrated degraded signals automatically test 10GBase-SR, 10GBase-LR, and 10GBase-ER optical interfaces, making the testers well suited for measuring XFP and other transceivers as well asline cards from 10-Gigabit Ethernet routers, switches, and servers as well as SONET/SDH (OC-192/STM-64), OTN (10.709-Gbit/sec), and DWDM transmission systems. OST Layer 1 degradations include added jitter, extinction-ratio level, optical-signal-to-noise-ratio level, interfering signal level, fourth-order Bessel-Thompson filter, optical power level, and PRBS errors. The OST 10E includes several features to ensure accuracy and repeatability, monitor device-under-test behavior, minimize testing time, optimize statistical measurements, sequence tests, and control external instruments such as oscilloscopes, environmental chambers, and power supplies.

The N2X multiservice tester combines leading-edge services testing with carrier-grade infrastructure testing and emulation, including routing, switching, transport, and storage. The architecture is based on programmable measurement test cards that offer best-in-class performance and can be updated to the latest standards. The cards plug into a common chassis and can be mixed and matched to create a realistic emulation that tests the performance of a service from the enterprise through the metro/access network and over the core network. The tester allows users to drill down and isolate problems in a specific part of the network or device. Network equipment manufacturers and service providers can more comprehensively test new services end-to-end and find problems faster and more thoroughly test an interdependent carrier-grade network. Services include metro Ethernet, IP/VPN, and L2oMPLS for ATM over the latest converged infrastructure standards such as MPLS, IPv6, and next-generation SONET.

The "flexible" 100% gel-free Indoor--Outdoor Ribbon Cable features a cross-ply strength element sheath, eliminating preferential bend directions so the cable can bend in every direction for greater flexibility when installed in tight premises locations and more complex fiber pathways. Its bend diameter is more than 40% smaller, giving users about twice the flexibility for quicker and easier installations. The riser-rated cable eliminates the need for installers to switch from an outside plant to a premises cable, since it can be installed from the last termination in the outside plant environment into the building, allowing for a seamless splice-free fiber flow. By incorporating water-blocking yarns into the cable design, there is no need for gels in the cable's core and central tube, further reducing installer cable preparation time. The cable can be used for direct-buried and lashed-aerial applications and has up to 600-lb tensile strength. It is UL- and OFNR-listed for riser flammability requirements and meets Telcordia GR-20 and GR-409 standards as well as ICEA 640 requirements.Sumitomo Electric Lightwave, Research Triangle Park, NC, www.sumitomoelectric.com

Doubling the fiber count under one jacket, the 288-fiber RLT riser loose tube cable for indoor and outdoor applications allows for more populated backbones without having to run multiple cables between buildings, floors, or telecommunications closets. It meets OFNR riser-rated specifications to eliminate the need for termination within 50 ft of demarcation within a building. Available in singlemode and multimode 62.5- and 50-µm designs, the cable can be produced with laser-optimized 50-µm MaxCap multimode fiber for high-speed 10-Gbit/sec backbone applications. It also meets all standards for tray installations (UL-, ETL-, and CSA-certified) and comes with a single PVC jacket, double jacket, or added corrugated steel armoring.

The high-channel-count, scalable multiplexer/demultiplexer modules based on thin-film-filter (TFF) technology provide full expandability of up to 40 channels in DWDM networks. The same module can be used in multiplexing/demultiplexing and reconfigurable optical add/drop applications. Upgrades can be handled in 8-10-channel increments in any wavelength order with minimal insertion loss increase. Optical filtering based on "banded architecture" arranges separate optical communications channelson a particular wavelength into groups-instead of processing the channels one at a time, the filter processes the group, reducing overall footprint and optimizing device efficiency and without skipping or sacrificing the neighboring channels.
