The HFBR-7934Z four-channel parallel optical transceiver module complies with RoHS 6 and operates at 3.125 Gbits/sec per channel for an aggregate bandwidth of 12.5 Gbits/sec and a link distance up to 350 m. This distance and high-bandwidth capacity provide the flexibility to create larger systems in central offices or large enterprises, helping meet the demand for terabit data transfer. It is compliant with the POP4 multisource agreement, uses an MTP/MPO ribbon fiber connector interface, and features electrical connection via the pluggable 10×10 Meg-Array connector system. The module is available in four configurations for EMI and heat sink options.
The flexible, scalable Cannon PHD line of optical interconnects enables a higher density optical system than traditional SC, ST, or MC ferrule technologies. Based on an industry-standard 1.25-mm ceramic ferrule, the optical core connector bodies and structured cable systems are highly robust, delivering reduced insertion loss, less channel-to-channel variance, and higher return loss. The product’s end face is GR-326 compliant. Specific systems may be identified for panel mounting, use on backplanes and rack and panel designs, interface with the standard MIL-C-38999 footprint, or applications in outdoor and factory environments where commodity fiber-optic products prove unsuitable.

The GPON Class B+ family of optical transceivers can recover every bit from the first bit of the incoming optical signal running in burst mode, offering 28-dB loss budget and 20-dB dynamic range without power leveling scheme. The transceivers are also compatible to both reset and reset-less GPON system design with Digital Diagnostic Monitoring interface on both ends. The product line is based on small form factor (SFF) and small form factor pluggable (SFP) multisource agreements. On the optical network terminal side, the RoHS-compliant devices serve both diplexer and triplexer version transceivers supporting Multimedia over Coax Alliance (MoCA) functionality and work in the industrial temperature range.

Version 7.0 of the Passive Component Design Suite, which includes the BeamPROP, FullWAVE, BandSOLVE, GratingMOD, DiffractMOD, FemSIM, and MOST tools, now incorporates advanced nonuniform mesh generation and improved speed and usability. By reducing the number of grid points, FullWAVE, an FDTD-based simulator, can perform more quickly when using a nonuniform mesh compared to a simulation with a uniform mesh. New algorithms for FemSIM and DiffractMOD allow similar accuracy to be obtained at less computational expense compared to previous versions. All products, including GratingMOD, are now tightly integrated with MOST, a scanning and optimization tool.
RSoft Design Group,
Designed for fully automatic, precision microelectronics assembly, the computer-controlled work cell in the Mode 3500-II die bonder performs adhesive dispense, component placement, die attach, and flip-chip operations over a 0.46-m2 work area. Applications include flip chip, stacked die, MEMS devices, multichip modules, optoelectronic modules, and hybrid microcircuits. Soft touchdown or noncontact laser height-sensing mechanisms assist in precise pickup and placement of fragile devices. An eight-position turret head can rapidly change tools on the fly without a space- and time-consuming tool dock assembly.
The latest version of the waveguide optics design suite, OptiBPM 8, adds new mode solvers for circular fibers, powerful optimization engines, and increased simulation performance. Advanced LP and vector mode solvers for circular fibers find modes using a transfer matrix method in cylindrical coordinates. The optimization feature accommodates user-defined functions of merit and employs one of three powerful optimization strategies: the Golden Search Method, Nelder-Mead Simplex Method, or the Modified Powell Method (a direction set method). Additional features include the ability to import DXF and GDSII mask file formats and a simulation engine performance boost allowing OptiBPM 8 to run 50% faster than previous versions.
Standard-function narrow (SFN) switches use third-generation switch technology to lower installed costs between 20% and 70% compared with current market offerings. The switches provide low-cost, fully industrially hardened, entry-level switch functions with five or eight ports (10/100 Mbits/sec) in a narrow housing width. These include a complete range of 100-Mbit/sec glass fiber configurations that support SC or ST style connectors. Optional security frames can be used to block unused RJ45 ports and lock in existing cables, restricting network access by unauthorized personnel. All SFN switches have the ability to read “quality of service” prioritized messages and process critical control messages before normal priority messages.
The Netstender platform now supports 10-Gbit Ethernet and OC-192/STM-64 interfaces with the 10-Gbit/sec wavelength conversion module for metropolitan and regional networks. Using pluggable optics on line ports, the module can translate any optical interface (850-nm, 1,310-nm, DWDM) to any wavelength with full performance statistics, allowing service providers to profitably offer 10-Gbit/sec services with service-level agreements. The plug-in unit supports client port utilization data and performance monitoring of both line and client signals to deliver 10-Gbit/sec transport, network demarcation, LAN-PHY point-to-point extension, and router port long-span performance.
BTI Photonic Systems,
With the compact Free-Light, a 10-Gbit/sec widely tunable transponder designed for metropolitan area and long-haul networks that use reconfigurable optical add/drop multiplexers (ROADMs), carriers can expect to reduce the number of transponder spare parts needed from 40/80 to one, since the single transponder can replace any working transponder in the commonly used ITU-T grid. It remotely selects and changes the actual wavelength, provisions new wavelengths, and enables the rerouting of existing ones. Designed for ECI’s XDM All Range WDM/ROADM system and part of ECI’s OTN offerings, the highly compact transponder plugs into the XDM universal traffic card.

The ultrathin PureGain 400 erbium-doped fiber amplifier (EDFA) module is 7.5 mm thick, designed to work within the strict space constraints in transponder and line card applications. The module can be used in a preamplifier configuration, which enables high receiver sensitivity without a transimpedance amplifier, or a booster configuration, which enables high launch power in advanced transmitter designs. It incorporates standard optical components and is compatible with Telcordia requirements.
A complete family of optical power meters is available for precision optical power measurements, peak detection, and laser tweaking. Sets include display and sensor units covering an overall optical power range of 5 nW to 30 W and a wavelength range of 250 nm to 10.6 µm. The family comprises sets with standard semiconductor and thermal sensors as well as those with thin profile sensors or integrating sphere sensors. Display options include a multifunctional digital handheld console or a large, mirrored, and easy-to-read analog display. All power meters automatically recognize the connected sensor and download the calibration data stored in the sensor head.
The Noyes M200 optical time-domain reflectometer (OTDR) offers fiber-optic cable test and trouble-shooting capabilities in a handheld package weighing less than 2 lb. Three models are offered: the M200-MM (850/1,300-nm multimode) and M200-Quad (850/1,300-nm multimode plus 1,310/1,550-nm singlemode), suitable for Tier 2 certification of premises fiber-optic networks, and the M200-SM (1,310/1,550-nm singlemode), designed to test and troubleshoot FTTX and fiber-optic access networks. Data can be stored on the internal, nonvolatile memory (more than 100 traces) or CompactFlash removable media (thousands of traces per card).
The OP815D insertion loss measurement instrument is optimized for large-core optical fibers from 100 to 1,000 µm, including silica and plastic optical fibers. Integrating a stable laser or LED source and a precision optical power meter in a chassis measuring only 8.5×3.5×12 inches, this unit can be operated via the front panel controls or automated over a USB interface by OPLPro turnkey application software. The OP815D can be customized for measurement tasks in the lab or in high-volume manufacturing environments.
