The 8×8 all-optical optomechanical broadcast switch is designed for applications requiring information from a source distributed to multiple destinations such as SANs, video on demand, and distributed data processing. The switch offers excellent repeatability, low insertion loss, and low power consumption. It can be configured as a broadcast switch, crossconnect, or protection switch. In multicast or broadcast mode, any input channel can be routed to any combination of output channels with switching time <15 msec. The switch enables such services as lambda sharing and optical virtual private networks, and it can be built with multimode fibers.

The XL-TT10G small-form-factor 10-Gbit/sec widely tunable transponder in a 300-pin 3.5×4×0.53-inch multisource-agreement (MSA) package tunes over the entire C- or L- band with wavelength spacing of 50 or 100 GHz and supports multiple data rates, including 9.95, 10.3, 10.66, 10.7, 11.1, and 12.5 Gbits/sec. The transponder is offered with an avalanche photodiode or PIN receiver and an X or Z cut modulator (0 or -0.7 chirp). Tuning the transponder wavelength is done using the standard I2C communications link and commands or by using the three tuning control pins in the MSA connector or tuning it offline with an evaluation board and control software over eight wavelengths around the preset central wavelength.

The CrossWave 1400 1×4 MEMS-based all-optical subsystem is a building block for transparent N×N wavelength switching nodes in long-haul, ultra-long-haul, and regional carrier networks. It integrates DWDM demultiplexing, switching, and multiplexing functions into a single device, providing wavelength granularity switching between the input and output ports. Designed to handle up to 96 wavelengths per fiber at 50-GHz channel spacing in the C-band, the switching subsystem enables a variety of wavelength-crossconnect (WXC) architectures, giving system designers a way to build highly scalable and upgradable N×N WXCs (8×8 and beyond). Also, OEMs can create a typical 4×4 WXC with only four subsystems.

Designed for enterprise, metro, and core networks, the VSC3138 (40×40) and VSC3139 (72×72) fully nonblocking asynchronous crosspoint switches carry broadband data streams at rates to 3.6 Gbits/sec. Applications include SONET-based and DWDM core and metro optical-networking equipment, SAN switches, and digital video equipment. The switches include multiple programming ports (parallel, serial, and a secondary serial port) with multicast, broadcast, and striping programming modes. The 3.6-Gbit/sec data rate-per-channel capability enables optical-electrical-optical switching of 40-Gbit/sec very-short-reach data rates when routed as 12 × 3.6-Gbit/sec signals. The switches incorporate proprietary integrated signal equalization capability to eliminate the effects of intersymbol interference when long, narrow PCB traces are used. To support board-level manufacturability, they also incorporate on-board PRBS generator/detector, integrated temperature sensor/alarm, boundary scan support, and the ability to force or sense signals on any pin through a single port.

The MPAK multifiber two-piece connector system comprises of a female connector and male jack with 6 MT-style ferrules for a total of 48, 72, or 144 optical fibers, depending on ferrule configuration. It includes rugged nickel-plated cast zinc housings that shield and isolate electromagnetic interference. Dual shutters, one each on the connector and the jack, offer dust and eye safety protection. Designed to Telcordia GR-1435-CORE requirements, the connector system comes in singlemode and multimode versions and in combination as well as card and chassis mount versions. An optional integrated device shutoff can shut down the active device when not in use, extending component life.

The ME7894A optical-component test system for WDM transmission systems operating in the C- and L-bands comprises an advanced tunable-laser source with 70-dB optical signal-to-noise ratio and high power output; optical power meter; high-sensitivity sensor; and control software. Measurements are in <10 sec when the number of measured points is 5,001 at a 20-nm wavelength range and 4-pm wavelength resolution. Dual-channel feature allows automatic measurement of up to two channels simultaneously, and results are displayed graphically. Dynamic range of >50 dB allows the test system to conduct accurate analysis of optical filters, couplers, isolators, and splitters during R&D and manufacturing.

The 819xxA compact high-power tunable-laser source for testing next-generation active and broadband passive components helps component manufacturers speed development, without the need for an additional booster erbium-doped fiber amplifier (EDFA). Optical output power of 13 dBm and stimulated Brillouin scattering suppression allow high-launch powers in optical fibers, enabling testing of nonlinear effects in metro, DWDM and 40-Gbit/sec applications. The high-output power helps overcome losses in test setups or in the device under test, so engineers can test EDFAs, Raman amplifiers, semiconductor optical amplifiers, and erbium-doped waveguide amplifiers to their limits. The instrument provides wide wavelength coverage of 110 nm within the S-,C-, and L-bands.

The enhanced BandSOLVE 1.1 design software for calculating photonic band structures is built from the ground up to simplify the design and analysis of all photonic-crystal (PC) devices. Users can create PC designs in an intuitive CAD interface, then generate accurate band structures and mode profiles with just a few mouse clicks. The software handles arbitrary structures in one, two, or three dimensions and can analyze numerous modal properties. Enhancements focus on the design of PC slabs; algorithmic upgrades have also increased the software's speed.

The handheld Fiber Optic Visible Fault Finder Kit provides installers/troubleshooters with a dual-laser visible light source to locate excessive bends, kinks, and breaks in fiber-optic cables. It is also suited for optimizing splices and MT-RJ prepolished connectors during field termination. The kit contains two built-in independently switchable 635-nm visible laser sources, which can be operated in continuous wave mode or modulated at 3 Hz (flashing), 500 Hz, and 2 kHz, so the unit can be used as a tracer signal generator in conjunction with fiber identifiers or optical leak detection probes. AC- or battery-powered, the kit comes with a quickly rechargeable battery as well as status indication. It also comes in a durable waterproof carrying case with a plastic laminated instruction booklet.
