Cable assembly test system
The IQS-12001B interconnect assembly loss test system performs fast automated insertion loss and reflectance measurements on patch-cord, multifiber, and other interconnect assemblies in the manufacturing environment. The mandrel-free system is especially suited for hard-to-test fanout and hybrid assemblies. Remote-monitoring configuration saves time by providing access to the test setup. One software application enables system configuration to test multimode and singlemode fibers, all connector types, without an additional PC. The high-throughput configuration for insertion loss and reflectance measurements doubles the number of switch ports and adds a loss meter to the configuration to allow hybrid-patch-cord testing in one batch.

The TLS-8800 Series precision tunable-laser sources-TLS-8801 C-band and TLS-8802 L-band-provide high-output power, absolute wavelength accuracy, and power flatness over the tuning range-all in a one compact instrument. An integrated wavelength monitor achieves absolute wavelength accuracy of ±1 pm with 13 dBm of output power. An integrated power monitor maintains ±0.05 dB over the full tuning range. Power stability is ±0.01 dB over one hour and ±0.03dB over 24 hours.

The OPX-192 bit-error-rate (BER) tester, part of the AX/4000 product family, is specifically designed for the stringent testing requirements associated with core and metro-area networks. It verifies that network devices meet BER requirements and conform to the SONET/SDH standard, including reporting alarms/errors and protection switching, before deployment. The tester also enables the mapping of payloads from STS-192/AU-4-64 down to STS-1, in any valid combination, and can test up to 192 channels simultaneously and independently. The OPX-192 helps accelerate time-to-market and ensure network and equipment performance, allowing better use of engineering resources and reduced testing time and space requirements.

Hybrid alignment engine
F-130 NanoAlignment Engine is designed to provide very-high-precision alignments for companies that do not want to invest in a fully automated packaging solution. It features 3-6 degrees of freedom and combines compact motorized stages (50-nm resolution) for intelligent pre-alignment with ultra-precise piezo technology (1-nm resolution). This hybrid ultra-low-inertia approach means that during the alignment process only the small mass of the PZT scanner moves, allowing for short alignment times.

Dispensing pen system
The Mikros dispensing pen system improves fluid control and minimizes waste in fiber-optic assembly processes where precise amounts of two-part epoxies, UV-cure adhesives, and other expensive fluids are required. Used with air-powered dispensers, the dispensing system produces consistent micro-deposits as small as 0.007 inch in diameter. Disposable reservoir tips with 0.25-cc capacity reduce waste by allowing expensive adhesives to be mixed in small batches and consumed before working time expires. Silicone-free reservoir tips have 30-, 32-, or 33-gauge needles and block UV wavelengths between 280 and 390 nm.
