The 3500-II component-assembly cell for micro-electromechanical systems (MEMS) applications provides 5-mm accuracy placement in the X, Y, and Z axes and 0.2 milliradians in the theta axis to reduce yield losses by eliminating the need for human handling and increase packaging reliability and performance through repetitive and accurate component placement and attachment. Once the parts have been presented for assembly, the cell picks and places them into the package for bonding. The machine has flip-chip capability if the component must be turned over before being placed. It can accommodate all types of attach methods, including epoxy, eutectic soldering with tightly controlled heat regulation, thermocompression, and thermosonic bonding on gold ball bumps.

The AutoStrip automatic optical-fiber window-stripping unit handles the difficult and potentially hazardous task of removing a section of the fiber's coating (80/250/400 mm), without causing any damage or leaving residue on the fiber's bare glass. It eliminates the need for dangerous hot acid baths to strip and clean optical fibers at very high strength. At the touch of a button, the unit automatically adjusts to a specified strip length (2 mm up to 150 mm) and completes the window-stripping process, leaving the fiber at near-virgin strength (~700 kpsi). Its compact benchtop design is suited for optical manufacturing applications and R&D laboratories. The unit is PC-controllable, making it simple to operate and program, and features a built-in state-of-the-art tensile strength linear pull tester.

The TC3210 10/100Base-T-to-fiber Ethernet media converter handles high-temperatures (-40° to +80°C) as well as distances up to 100 km and features power redundancy and two-way optional "single" fiber capability available on singlemode fiber-optic cable. It is auto-negotiating for 10- and 100-Mbit/sec Ethernet links to convert 10/100-Mbit/sec Ethernet unshielded twisted-pair to singlemode (1300/1500-nm) or multimode (1300-nm) fiber optics. Transparent to the network, the converter operates efficiently even during high-demand traffic loads, according to the company. Power is 12 VDC, or optionally, 24 VDC, 48 VDC, or 115/230 VAC with an external power cube. Dry contact alarms are provided for connection to remote network management systems. Local loopback, five LED indicators, and an uplink/downlink slide switch are provided to aid in installation and troubleshooting. The converter is available in standalone or rackmount.

The 10-Gbit/sec MSA (multisource agreement) line of optical transponders was designed with a very small footprint (75×55×12 mm), enabling easy integration with large-capacity optical transmission systems and high-speed IP routers and reducing the development period and equipment size needed for large-capacity systems. The OD-J8665, OD-J8666, OD-J8791, OD-J8792, OD-J8793 and OD-J8794 transponders require 4-6 W of power to operate; support bit rates of 9.95, 10.3, and 10.7 Gbits/sec as well as distances of SR-2 (25 km) and IR-2 (40 km); and support 300-pin MSA specifications proposed by 11 leading optical module vendors. The transponders also support SONET, SDH, and 10-Gbit/sec Ethernet applications; operate in temperatures of -5° to +70°C; and feature cooled EML and pin-PD optical modules, a built-in 16:1 multiplexer and 1:16 demultiplexer, and a 6xx.xx-Mbit/sec LVDS electrical interface.

For users developing short-, intermediate-, and long-reach (SR/IR/LR) systems, the SuperPHY physical layer device consists of several AnyReach solutions. The S19211 IR CMOS transceiver operates at low power (900 mW), with an operating range of 9.9-11.1 Gbits/sec to enable transport of forward-error-correction-encoded 10-Gigabit Ethernet data through metropolitan applications. The S192215 protocol-agnostic, hot-pluggable 10-Gbit/sec transceiver supports the SFI-4.2 OIF standard interface for multiprotocol traffice over the same link and leverages the cost structure of common module platforms via XENPAK, XPAK, and future generations of four-channel small-form-factor optical modules. The S3193 10.7-Gbit/sec transmitter/S3094 receiver incorporates EYEMAX technology with proprietary dispersion compensation circuitry, enabling users to achieve significant amounts of coding gain.

The ParaLink-P pluggable 12-channel parallel module for high-speed, high-density optical data transfer applications like optical crossconnects and terabit routers plug into a 10×10 ball-grid-array socket previously mounted on the motherboard to allow for more flexible final assembly, test, and repair. It comes in separate transmitter and receiver modules. The transmitter is based on a VCSEL array with monitor feedback, providing constant optical output over the transmitter's life, and the receiver has a highly sensitive GaAs PIN photodetector array. ParaLink operates up to 2.7 Gbits/sec per channel for total data throughput up to 32.4 Gbits/sec over 200 m on 62.5-mm core multimode fiber, provides low power consumption, is compact (54×18 mm), and has a low profile (8.4 mm). The optical interface is an MT-based MPO/MTP receptacle for easy connection to standard 12-fiber-based ribbon cable.

The ResiLink LT aerial drop cable for last mile fiber-to-the-home applications comprises a loose tube buffer containing up to four optical cables and a stainless steel messenger to enable self-supporting aerial applications up to 200 ft. The messenger resists corrosion and for easy installation can be inserted into a vise-like device made for wire and adjusted to the proper tension. In addition to durability, the cable is designed for easy access to optical fibers for splicing. The tube and messenger are connected in a zipcord-style construction that allows the separation of the two components at the point where the messenger is anchored and full protection of the optical fibers up to the point of termination.

The 2520INT integrating sphere photodetector, together with the company's 2520 pulsed laser-diode test system, provides a complete pulsed source and measure solution for light-current-voltage (LIV) testing of 980- and 1480-nm EDFA pump lasers, Raman amplifiers, laser diodes, and high-power vertical-cavity surface-emitting lasers (VCSELs). It offers production test engineers the flexibility to test devices earlier in the production process, so non-compliant devices can be detected before they are packaged. High-accuracy measurements of laser-diode optical power at the wafer, bar, or chip level are provided before integration into complete temperature-controlled laser-diode modules. Designed for production and laboratory environments, the photodetector uses a 1-inch sphere with a germanium detector to give a wide operating range of wavelengths, maximize easy setup and integration, and achieve low-level power measurement. It also shortens testing time by offering an SMA fiber tap to allow measured light to be sent to another instrument simultaneously for additional optical measurements.
