For use in XENPAK, XPAK, X2 and XFP optical-transceiver modules, the NR3312 10-Gbit/sec PIN-type ROSA is designed for operation to 100°C, providing very high heat tolerance and a 15°C improvement. To match the applied voltage of customers’ transimpedance amplifiers, the ROSA’s applied voltage was reduced from 5 to 3.3 V, enabling the module to be used with a single-source power supply. The NR4210 highly sensitive APD-type ROSA provides high-speed performance and efficient conversion of optical to electronic signals. It delivers excellent signal integrity, with a sensitivity rating of -28 dBm, a 3-dBm improvement. The PIN and APD modules offer SC and LC sleeves to make them compatible with high-speed transceiver modules. They’re also designed to support flexible printed circuit boards.
PureAccess bend-insensitive fiber drop cables for FTTP and FTTH applications combine low bending loss with easy entry-cable designs to facilitate easier fiber handling for tight bends at the edges of walls and tighter fiber coiling within entry ports and network interface devices located at the premises, multiple-dwelling unit, or home. The drop-cable fibers have minimum bend radii of 15 mm, a 50% decrease in bend sensitivity to allow for even greater fiber density with low bending loss for component and tight access wiring. When wrapped around a 30-mm-diameter mandrel, the fiber exhibits no additional attenuation loss, thereby preserving signal strength.

The LambdaNode 2000 all-optical switch eliminates the need for OEO conversions that slow high-bandwidth data transmissions in traditional optical networks, and the integrated LambdaCreate network management suite empowers organizations to develop high-performance agile all-optical networks that support growing requirements for high-bandwidth services and advanced applications. The switch uses 3D MEMS for reliable, rapid switch time and low signal loss. Built for ring, mesh, and ring/mesh metro and regional networks, it fully integrates DWDM technology, allowing diverse packet formats to travel together at the same time on one optical fiber. Protocol-agnostic, the switch is compatible with GMPLS. The software suite enables remote real time end-to-end control of the switches in the metro/regional network, reducing the need for manual provisioning and network management, speeding service delivery, and boosting network performance. Fully FCAPS-compatible, the software’s intuitive point and click graphic interface provides a single view of the entire network and each switch.
Using the bidirectional adaptive optics method of beam control, the GT1.0 communicator reaches a range of >20 km with low probability of intercept or detection due to its intrinsic ability to control the beam diameter down to a few centimeters. The system provides 800-Gbit/sec bandwidth with a fiber source and 1-Gigabit Ethernet bandwidth with a COM interface. It’s packaged in a 9×13×13-inch chassis that operates on battery power for >8 hours continuously, weighs just 12 kg, can be tripod mounted, is fully man-portable, and comes ready for field deployment. For ground applications, the optical subsystem enables building-to-building (in-room) line-of-sight links directly though windows with no performance degradation. The system’s highly optimized beam delivering 200X the power also allows for low power operation and significant range improvement in challenging environments. Near-field range is 250 m from a single aperture/terminal with the automatic operator-adjustable optics module.

DTX CableAnalyzer accessories include copper and fiber adapters that allow users to test a greater number of links and measure insertion loss in a shorter period of time. The adapters also allow testing of coaxial cables for video distribution or legacy-network coax cabling as well as patch cords to ensure optimal network performance and full compliance with the TIA/ISO patch-cord standards. The DTX-GFM contains a set of two gigabit multimode fiber modules, each incorporating an 850-nm VCSEL source and 1310-nm laser source combined into a single output port with an integrated VFL. The modules minimize test time to a 12-sec auto test that includes loss measurements for both fibers in the link each at both wavelengths as well as a length measurement. The tester calculates the loss limits based on the length and provides a clear pass/fail indication with margin calculations. Tests can be executed in record time-at least three to five times faster. All DTX testing is in full compliance with Category 5e and 6 as well emerging cabling technologies such as 10-Gigabit Ethernet and Class F/Category 7.
The rugged, portable OptiVisor 400 provides full OTDR testing flexibility with field-interchangeable multimode, singlemode, and combination modules, which can be easily switched out in the field without using tools. The unit can provide full test results four times faster in as little as 45 sec. It features a 7.7-inch color LCD touchscreen large enough to view both the trace and event table. Internal memory stores of up to 700 traces, eliminating the need for a hard drive. If extra storage is needed, the mainframe contains a floppy drive and PCMCIA port. The OTDR’s modules provide a standard continuous wave source, while the mainframe offers an optional power meter, reducing the overall amount of test equipment required for system qualification by integrating power-through testing directly onto the OTDR platform. An optional visual fault locator, useful for fiber identification and troubleshooting, is available on all modules. Auto mode allows users to select parameters automatically, advanced mode offers more setup and measurement capabilities for the more experienced user, and template trace mode allows creation of a template for comparison with other traces, especially for quick testing multiple fibers.

For SONET/SDH, DWDM, 10-Gigabit Ethernet, and Fibre Channel systems, the FronTera FT2010 and FT3010 10-Gbit/sec transponders enable up to 200-km transmission without dispersion compensation over the existing fiber infrastructure, allowing service providers a simple network upgrade with high transponder performance. Based on FTDB technology, the transponders allow smooth network upgrades from 2.5 to 10 Gbits/sec, easy and flexible network design, ring consolidation, and network coverage expansion. They are bit-rate-independent, 300-pin MSA-compatible, and compatible with existing NRZ transponders. They also have a higher range without additional network elements and ensure reliable operation, while meeting the demands of the Telecordia GR-253-CORE and ITU-T G.691 and G.692.
