The SpecMap fiber-optic interferometer provides advanced noncontacting optics with high-speed data acquisition and analysis. All critical surface geometries are measured for single-fiber connectors and multifiber arrays containing up to 72 fibers. The compact interferometer's excellent vibration insensitivity and autofocus operation guarantees accurate and repeatable measurements under all environmental conditions.Krell Technologies, Overland Park, KS

For deployment and provisioning of DWDM and TDM high-speed optical networks, the handheld MPI-800 multipath interference meter contains a built-in loss measurement test set. It can detect multipath interference, a physical phenomenon prevalent in ultra-long-haul networks containing Raman amplifiers, which increase the signal in both directions, causing unwanted ghost reflections that can lead to an excessive bit-error rate. The meter provides a solution for network operators, who "up until now, were forced to adopt a complex setup using radio-frequency spectrum analyzers that are not designed for field-testing applications," claims EXFO product management vice president Étienne Gagnon.EXFO Electro-Optical Engineering, Quebec City

The Gemini Cx integrated polish, clean, and inspection automated manufacturing cell has a new process for terminating 24-fiber (MT-24) multifiber connectors to attain higher optical-fiber-connector densities in smaller-form-factor footprints required for numerous photonic applications. It addresses the challenges of achieving high-quality endfaces that are much greater for multifiber connectors than simplex connectors, particularly maintaining the protrusion uniformity of all 24 fibers within the connector. The machine maintains consistency not ..only between all 24 fibers within the individual connector, but also among all the multifiber connectors within the high-volume polishing fixture designed for batch-polishing MT-24s. Features include a floating gimbal head, adaptive force control, and roll-to-roll polishing media dispensing.Sagitta, Hauppauge, NY

Designed for data rates from 155 Mbits/sec to 2.67 Gbits/sec, the FTM-6128C-S80xx multirate CWDM small-form-factor-pluggable (SFP) optical transceiver provides an enhanced monitoring interface compliant with SFF-8472. It is available in eight standard CWDM wavelength channels (1470–1610 nm) and offers a guaranteed minimum optical link budget of 28 dB. The monitoring interface allows real time measurement of the transceiver's key operational parameters such as optical input and output power, supply voltage, bias current, and module temperature to help monitor and manage system performance.Fiberxon Technology, Shenzhen, China, and Santa Clara, CA

The small-form-factor-pluggable (SFP) optical transceiver comes in eight ITU-..compliant CWDM wavelengths (1470–1610 nm), with color-coding by wavelength for easy identification. Using high-performance, uncooled distributed feedback lasers and optimum thermal design, the transceivers support 1.25-Gbit/sec Gigabit Ethernet, 2.5-Gbit/sec STM-16/OC-48, and 2.7-Gbit/sec STM-16/OC-48 with forward error correction, achieving transmission distances of 40 km with a PIN photodiode (PD) receiver and 80 km with an avalanche PD. They comply fully with the SFP multisource agreement, include built-in digital diagnostic functions, and operate from a single 3.3-Vdc supply.

"About a year ago," notes Tellium chairman and CEO Harry Carr, "we started working closely with many tier one carriers around the world concerning the challenges facing their networks...to meet current and future needs in optical switching." The result is the Aurora MTX series of multiservice transport switches, designed to address carrier needs beyond the core of long-haul networks by eliminating the need for separate broadband and wideband digital-crossconnect systems, add/drop multiplexers, and Ethernet switches, thus supplying unified transport and switching for both legacy TDM and new data services. The switches will support ring and mesh topologies and handle aggregation and transport from 1.5 Mbits/sec to 10 Gbits/sec, including support for Gigabit Ethernet services.

Designed to provide 25% greater port density, the 10-port Gigabit Ethernet multiplexer is targeted at cable multisystem operators, which Sorrento Networks chairman and CEO Phil Arneson describes as "starting to spend heavily in rolling out VoD [video on demand] services." With the higher port count, cable service providers can use fewer wavelengths to transport a given amount of VoD traffic, meaning less equipment, less rack space, less power, and fewer potential points of failure. The multiplexer module takes only two slots in the 17-slot GigaMux platform.Sorrento Networks, San Diego

Meeting Telcordia 1209 and 1221 standards for expanding high-capacity networks from the enterprise to the core, the SpectraMux compact coarse wavelength-division multiplexer/demultiplexer has channel spacing of 20 nm and wide bandpass characteristics for use with non-temperature-controlled lasers. It also ..provides high center wavelength accuracy and stability, low insertion loss, high directivity, an epoxy-free optical path, and low polarization-dependent loss. The mux/demux comes in four or eight channels and includes an expansion port for 16-channel systems.

Integrating a variable optical attenuator (VOA) and equipped for mid-stage access in central-office applications, the SmartGAIN optical amplifier provides a variable gain from 15 to 30 dB without affecting output flatness. It suppresses optical power surge within 100 µsec even when 31 of 32 channels are dropped. With an output power up to 20 dBm, the amplifier allows a mid-span loss of 10 dB or more, regardless of the fiber loss or the insertion of dispersion compensation elements. It offers 40-dB dynamic range for optical power detection, allowing the network to have rapid changes in its configuration while keeping existing communications channels intact.

Plugged directly into the WAN port of such devices as Layer 2 switches, the pluggable transponder for metro/access applications is part of an end-to-end optical-networking solution that can be managed all the way to the client port, providing a new optical demarcation point on the customer premises. "While GBICs can prove to be a viable alternative to external transponder-based solutions for enterprise applications, service providers wish to have end-to-end control of the transmission domain from within the optical layer management system," reasons CEO Isaac Olasoko.

The plastic High-Security Pedestal for improving network security and reducing cable-signal theft is molded from modified linear low-density polyethylene, designed to resist impact, ultraviolet, and environmental degradation. It includes a ground retention system so the pedestal cannot be pulled out of the ground without the use of heavy equipment, a custom-designed lock-protector that prevents breaking the lock with common hand tools such as screwdrivers or hammers, and heavy-gauge mounting reinforcement plates that stop thieves from breaking into potential weak points at the mounting and bolted areas. The pedestal features 360-degree access and rugged economical construction. It includes multiple stake, lock, and bracketry options, and the factory-assembled lock and stake arrive ready to install. A name plate or logo option as well as ventilation options can be customized. Corning Cable Systems, Hickory, NC

Plug and play cassettes and MTP pre-terminated cables ease installation of fiber-optic links because connector terminations are not required in the field. The system is especially suited for zone cabling applications where network configurations may be required or installations where quick deployment of a fiber link is essential. The durable metal cassettes fit into fiber patch panels and enclosures that accept FSP series adapter panels. These compact housings contain factory-polished multifiber fanouts in SC, LC, ST, and MT-RJ connector styles for singlemode and 62.5- or 50-µm multimode fibers. The fanouts ..are terminated at the back of the cassette to a 12-fiber MTP receptacle. Factory-terminated, plenum-rated, 12-fiber MTP cables come in 10-, 25-, 50-, and 100-m standard lengths—other lengths can be special-ordered. The cables have a pulling grip attached at one end for easy pulls through conduit and innerduct.
