AIflex allows customers with access to fiber-optic lines to extend their LAN, providing the bandwidth to support both enterprise applications and operation, administration, maintenance, and provisioning. AIflex has obtained Network Equipment Building Standard level 3 certification. The AIflex is used to extend LANs by either utilizing unused fiber or WDM technology. Management data may be sent on the same fiber line as SONET or DWDM with AIflex without interfering with the existing payload or needing to bring down the fiber during installation. Provisioning time is reduced with no wait for T1 engineering and provisioning. The T1 line installation cost and monthly recurring costs are eliminated.

The Q8326 Optical Wave length Meter tests next-generation transmission laser diodes whose tolerances have narrowed due to the increased bandwidth demands of the Internet. The Q8326 enables designers, manufacturers, and users of DWDM components to quickly and accurately test the compliance of transmission laser diodes and optical filters. It has a high wavelength accuracy of ±2 parts per million and makes measurements with a high resolution of up to 0.1 pm. A sampling rate of five measurements-per-second enables a quick evaluation of laser diodes. The deviation display function allows the Q8326 to capture any minute wavelength fluctuations caused by temperature variations.

SYSTEMS & SUBSYSTEMS

The polarization-mode dispersion compensator (PMDC) eliminates distortion of optical signals over fiber-optic networks caused by asymmetries in fiber. The PMDC alleviates optical-signal distortion by adaptively canceling the polarization-mode dispersion at the receiver. The result is a cost-effective and reliable solution that alleviates the distortion. Additional features of the PMDC include a small footprint, low power dissipation, and a solid-state design.

The K2 uses powerful switching technologies that help carriers transcend metro gridlock, supercharging their optical networks with scalable, data-optimized, multiservice optical gear that integrate seamlessly and cost-effectively into existing metro access, metro transport, and metro core deployments. The K2 uses a combination of statistical multiplexing aggregation, preservation of native traffic protocols, arbitrary concatenation of SONET with traffic-based dynamic provisioning, and data grooming across the trans-metro. The K2's unconstrained architecture provides carriers with unmatched granularity and scalability from fractional DS-1 to multiple OC-192s, while supporting all prevailing packet and circuit-switching transport protocols. According to the company, the K2 is the only platform to support multiple simultaneous protection schemes as well as any topology.

COMPONENTS

The ATA7600D1 differential transimpedance amplifier (TIA) meets the performance and bandwidth demands of DWDM OC-192 systems driven by the increased demand for high-speed Internet connectivity. Operating at + 5 VDC, the InGaP HBT TIA provides low power consumption, low group delay, high gain, and low noise performance to enable high-speed, broadband fiber-optic systems. The ATA7600D1 is uniquely suited for 10-Gbit/sec and DWDM applications. The benefits of InGaP HBT processing include high reliability, resistance to temperature influences, and excellent performance uniformity. The ATA7600D1 dissipates a maximum of 500 mW and offers good gain flatness, low group delay (-20 to +20 psec), and low noise for WDM and DWDM applications. With a 9-GHz typical bandwidth, the TIA features a 0 dBm to -18.5 dBm dynamic optical range with a 1,550-nm PIN photodiode.

These interleavers with 100 and 50 GHz have low dispersion and are ready for 10-Gbit/sec and 40-Gbit/sec systems. They can be used with existing DWDM multiplexers and demultiplexers for next-generation terabit networks. The interleaver is a specialized multiplexer and demultiplexer. When used in the demultiplexer function, a denser signal stream is separated into two wider-spaced streams. Interleavers can be multistaged to increase the capacity of a system even further. The company can integrate the interleaver with other products, such as thin-film filter or arrayed waveguide grating multiplexer/demultiplexer, to allow for 160 channels or more in one fiber. The interleaver also has the ability to separate and combine signals for optical add/drop applications.

The E6091A OTDR Toolkit II is a software package for use with any of its optical time-domain-reflectometer (OTDR) products. The software reduces the time needed for post-processing fiber measurement data through the use of advanced batch-mode and reporting functions. By organizing a single project test for a cable carrying hundreds of optical fibers, engineers and central-office planners get a better view of all their system-integration or installation projects. The toolkit allows them to create a customized event table for compiling acceptance reports and creating work orders for resplicing and repair. The software can show up to 40 individual traces on a display screen. In post-processing data, engineers or supervisors can use the toolkit to replicate the multifiber test principle characterized in testing with the company's E6000B Mini-OTDR, instead of analyzing each individual fiber or event. They can batch process two-way averaging and pass/fail data to cut post-processing time from days to minutes.
