Using Concours optical-circuit technology, 24-fiber fanout assemblies transition two multifiber ribbons into individual 900-µm buffered fibers for termination to any single-fiber or duplex connector type. The transition is protected with a compact, hard backing that adds strength to the low-profile design. Suited for all-optical module boxes and enclosures, “back-to-back” fanout design minimizes the transition space required for multifiber ribbon to individual buffered fibers by eliminating the cumbersome breakout box. The Concours circuit mechanical features couple the bare fiber and protective buffer tube to the flexible substrate, which eliminates fiber pistoning at the 900-250-µm transition, resulting in a highly reliable fanout interface for singlemode- or multimode-fiber types. The breakout assemblies eliminate the difficult fanout and furcation operations, the completed fanout coils easily into a normal fiber wrap eliminating special mounting of the transition. Unterminated assemblies are available in standard, stocked configurations. Available in any fiber count, the fanout design is suited for high-channel-count (16, 24, 32, 48, etc.) requirements, including multi-row MT ferrule termination and planar waveguide interfaces.US Conec, Hickory, NC, www.usconec.com

For next-generation multirate Fibre Channel (FC) and Gigabit Ethernet modules, the SFP chipset includes the VSC7977 bandwidth-selectable transimpedance amplifier (pictured) and VSC7964 monolithic laser driver and post-amplifier. Available with rate selection capabilities for 1, 2, and 4 Gbits/sec, the two-chip set reduces module chip count and provides enhanced SFP/SFF-8472-compliant digital-diagnostic capabilities critical for functionality and design flexibility. The chipset architecture and pin placement reduce manufacturer bill of materials and simplifies the assembly process to the point where all components, active and passive, can fit on a single side of a four-layer printed circuit board. The chipset also requires 50% less external passive components. At 4 Gbits/sec, the VSC7977 optical sensitivity adds over 6 dB of margin to the standard. The device also incorporates a linear photo current monitor, on-chip photodiode filter, and extended temperature range operation of -40° to +105°C.Vitesse Semiconductor, Camarillo, CA, www.vitesse.com

The Quick Assembly connectors and tool kit shorten the field termination process for ST or SC multimode connectors. Within 90 sec, the connector is connected to the fiber, epoxy is cured, and fiber endfaces are polished. The splice-less process requires only one tool, which can be used with one hand, and the termination procedure, especially suited for building cable applications, does not require special knowledge or training.Huber+Suhner, Essex, VT, www.hubersuhner.com

The LightGuard CE1000 (one-bay), CE2000 (two-bay), and CE3000 (three-bay) ECOE environmental sealed cabinets protect electronic equipment from corrosion, vandalism, and the effects of weather and fire. Since they are designed with aluminum, the cabinets are corrosion-resistant and provide a significant reduction in weight from earlier designs. The interior space has been maximized with more available space for electronic equipment, fiber interconnect/apparatus, and optical cable. The cabinets also bring the new capabilities of optional redundant air-conditioner units, dc power plants, and UPS systems. Designed and tested to exceed industry standards for protection of active and passive equipment in the harshest conditions, the cabinets come in a variety of sizes for small, medium, and large networks.

The 70,000-rpm multiconfiguration deterministic micro-grinding attachment is primarily used for high-precision diamond grinding of small concave and convex aspheric optical-mold inserts. The multiple configurations allow grinding in different setups to maximize productivity, including inside/outside-diameter, cross-axis, parallel, and WECS (workpiece measurement and error compensation system) grinding in high-production environments. The cross-axis grinding setup, for example, can be used on convex molds with resin-bonded diamond wheels, and the 45-degree setup is more suitable for small concave molds with electroplated diamond grinding wheels.

For high-volume batch processing of APC connectors, the Gemini-Cx integrated provides excellent geometry and surface finish. It is easily scalable to multiple sites without the need for increased staffing and training. With high-quality throughput of over 200 APC ends per hour, the automation cell is especially suited for FTTP suppliers as a turnkey alternative to brick and mortar expansion.

Designed for fiber to the premises access at Gigabit Ethernet rates, the BBS 1000 broadband access platform includes the OLT 100 optical line termination system for deployment at the central office, providing a direct optical interface to the Ethernet/IP network core, as well as the ONU 100 optical-network unit, which terminates the passive optical network (PON) at the customer premises. Together, the two units complete the end-to-end optical last mile, providing up to 1 Gbit/sec of bandwidth to residential and business customers. Advanced Layer 2 and Layer 3 switching and routing functionality eliminates the need for carriers to deploy additional network equipment for bandwidth-intensive triple-play services. Embedded operation, administration, and maintenance functions enable remote diagnosis, flexible provisioning, and system reconfiguration as well as remote system upgrades without hardware swap-out. Supporting up to eight PON links, the access platform meets the new IEEE802.3ah standard requirements for Ethernet PON.

The Fomux C100 compact fiber-optic multiplexer utilizing CWDM supports up to eight applications on a single fiber pair, with a maximum throughput of 2.5 Gbits/sec per channel. Protocol transparency provides multiplexing of all types of transmission such as Fast Ethernet, Fibre Channel, and Gigabit Ethernet. The integrated, flexible, scalable device is enhanced by quick-changing modules that allow for growth and expansion of topology, clocking, management, and power, all from the front of the rack-mounted chassis.Pandatel, Miami, FL, and Hamburg, Germany, www.pandatel.com

For measuring 10-Gbit/sec SONET/SDH and G.709 OTN jitter, hardware enhancements to the OmniBER OTN communications performance analyzer ensure a receiver-only fixed accuracy error of <15 mUI at 10 Gbits/sec. The high accuracy and repeatability reduces jitter measurement uncertainty by more than 50%, giving component suppliers and network equipment manufacturers more assurance of design conformance to the 100-mUI industry standard. Along with the enhancements, a new ITU-T O.172 Appendix VII-based calibration procedure provides a guaranteed accuracy specification.Agilent Technologies, Palo Alto, CA, www.agilent.comUsing the interferometric method as recommended by TIA FOTP-124, the CMA 5400 PMD 160 module, an addition to the CMA 5000 multilayer test platform, scans a range up to 160 psec, doubling the maximum polarization-mode dispersion (PMD) value measurable. Standard light sources, which allow 48 dB of dynamic range, cover most applications. An optional 65-dB light source is available to measure ultra-long-haul links. Cross-correlation technique and choice of light sources enable high dynamic range, fast accurate measurements, and the capability to measure PMD through EDFAs. A graphical user interface provides several modes of operation, including a histogram mode that tests the evolution of PMD with time and a multiple-scan mode that guides operators through the required steps to measure multiple scans over multiple fibers. A reporting feature can display graphs and statistical information as well as simple pass/fail test responses on the unit’s display, on paper, or as PDF files.NetTest, Utica, NY, www.nettest.com

For emerging standards like the OIF Common Electrical I/O (CEI) project, the electrical stressed eye testing capability is packaged in the OST optical-standards-tester platform to enable a variety of automated tests, including jitter, filter, interfering source, and signal-to-noise ratio. It will test the XFP transceiver’s XFI electrical interface and can be used to test other transceivers as well as line cards from 10-Gigabit Ethernet routers, switches, and servers and SONET/SDH (OC-192/STM-64), OTN (10.709-Gbit/sec), and DWDM transmission systems.
