The wavelength blocker is designed for optical add/drop multiplexing (OADM) applications in next-generation optical communication networks. The internal optical block has no moving parts and the package is based on a hermetic sealing structure for high operational stability and long-term reliability. Other features of the subsystem include C-band or L-band operation at 100- or 50-GHz spacing, wide passband with flat-topped channel profile, channel-by-channel attenuation and blocking, and high extinction ratio. In addition to its application for reconfigurable OADMs (ROADMs), the device also can be used for network management (protection and restoration) and dynamic channel power equalization.

New devices in the WaveReady product line are scalable WDM optical transport subsystems designed for metro, access, and enterprise optical networks. The flexible WRT-780 compact dual transponder is targeted for transport of any service (OTN, SONET, Ethernet, Fibre Channel) between 125 Mbits/sec and 4.25 Gbits/sec. The WRT-780 can be combined with other WaveReady WDM modules and chassis to provide cost-effective density for WDM transport. The WRA series user-configurable erbium-doped fiber amplifiers (EDFAs) are designed to transport DWDM optical network services up to 43 Gbits/sec. The EDFAs include the WRA-100 single-channel optical amplifiers, offered in four different gains or output powers to accommodate various optical link budgets, and the WRA-200 series of C-band multichannel optical amplifiers, featuring an ultrafast transient response.

Designed for service provider edge and enterprise networks, the BTI 7000 Series platform delivers HD video, LAN and storage extension, SONET/SDH network consolidation, Ethernet business services, and 4G wireless backhaul capabilities without the high costs associated with traditional metro optical and Ethernet switching technologies. With support for CWDM, DWDM, OTN, and Carrier Ethernet, combined with a rich set of transponders and muxponders, the platform is capable of extending multiprotocol gigabit services within existing budgets to the optical edge.BTI Systems, www.btisystems.com
OSP fiber enclosure
The FieldSmart Fiber Scalability Center (FSC) is a complete PON solution for managing up to 576 distribution fibers for an outside plant (OSP) FTTX application. The enclosure can provide up to 288 fibers in a compact 16�16�32-in. footprint or 576 fibers in a 33�16�32-in. design. Fiber is protected in sub-units of 12 fibers with the Clearview cassette technology. Jacketed cable storage is eliminated because the 900-µm tight buffers have shed the outer riser-rated jacket in favor of the cassette that protects it not only from human accidental damage but also provides full bend radius protection throughout. The FieldSmart FSC accommodates all fiber management needs plus all the required slack storage for a 288 home-served patch and splice configuration.

The FSM-60S fusion splicer is the next generation of the FSM-50S, which will continue to target the European telecom market. The new ruggedized machine is smaller and lighter than its predecessor, and offers increased protection from dust, water, vibration, and shock. The FSM-60S also has a battery that can be charged during normal operation, accommodates a variety of clamping systems, and has the option to incorporate a second heater.

The addition of Fibre Channel support to the recently introduced IQS-8120NGE and IQS-8130NGE Power Blazer multiservice test modules simplifies the testing of multiservice products by network equipment vendors. In addition to offering SONET/SDH/OTN, next-gen SONET/SDH, and Ethernet testing capabilities up to 10/10.7 Gbits/sec, the modules now offer optional support for 1�, 2�, 4�, and 10� Fibre Channel rates. This extension addresses the stringent testing requirements for multiservice products by system verification, R&D, and manufacturing groups, allowing them to easily perform automation along with test and troubleshooting routines on network equipment that supports different protocols on the same interface.

Two-stage fiber-optic distributor cables enable simpler, more compact installation and clearer cable routing. The new concept has high-fiber, preterminated loose tube cables that are divided at the factory over two or three spare conduits, each with four 12-fiber bundles (each conduit contains 48 fibers). The distributor heads fit into a standard one-height unit housing with 24 ports. By using routing frames, 96 or 144 fibers can be terminated with only two or three 19-in. standard housings. The preterminated FO cables come with protective tubes that can be easily removed during on-site installation.Dätwyler Cables International, www.daetwyler-cables.com
The VS-705, the fifth-generation of the company�s voltage-controlled SAW oscillator (VCSO) product, features an expanded frequency range (120 to 850 MHz) in a smaller package (5.0�7.5�2.5-mm LCC) and several improved performance and power management capabilities that support green initiatives. The VCSO is optimized for use in phase-locked loop (PLL) circuits that require excellent jitter filtering and a wider tuning range (±100 ppm APR), including high-speed data transmission applications such as Synchronous Ethernet, Fibre Channel, traditional SONET/SDH optical networking, and high-clock-rate base stations.

The Cannon PHD SuperLC connector features a small form factor and maintains the same high optical performance characteristics of a standard LC product while operating in severe environments. A thermal plastic housing and locking feature to prevent mechanical release allows the connector to withstand high temperatures and thermal cycling, along with elevated levels of shock and vibration. The SuperLC meets or exceeds Lucent 640-252-053 and Telcordia GR-326 requirements. The connector is suitable for military/aerospace, telecom service, and industrial data communications applications. The connector features a tunable optical cartridge that functions as a standalone optical element separate from the connector housing and accepts multimode or singlemode ferrules. The locking mechanism also prevents thermal stress of the latch at high temperatures. Crimp termination of the cable to the rear body ensures ease-of-use and quick field repair.
