Multiservice modules for testing
The multiservice module (MSM) product line provides testing of 2.5- and 10-Gbit/sec networks utilizing Packet over SONET/SDH (POS), Ethernet over SONET, and 10-Gbit Ethernet. Network equipment manufacturers can test for performance, scalability, and functional validation of MSPPs, MSSPs, edge and core routers, digital crossconnect systems, and add/drop multiplexers during product development; service providers can also use the modules to test during qualification and rollout of new infrastructure and services. Up to 16 ports in a single Optixia X16 or IXIA 1600T can generate traffic of millions of unique flows per port. The 2.5-Gbit/sec load module supports concatenated OC-48c POS, and the 10-Gbit/sec load module supports concatenated OC-192c POS and 10-Gbit Ethernet LANs/WANs.
The short-wavelength A2000 component analyzer operates in the 850- to 1100-nm range. When combined with a tunable laser, it allows measurement of PMD/DGD from less than 0.1 psec to more than 200 psec. The analyzer performs real-time polarization extinction ratio measurements on PM fibers to levels beyond 50 dB, using polarizationNAVIGATOR PC software that supports many popular automation interfaces. State and degree of polarization, as well as optical signal power, are sampled at rates up to 1 megasample/sec. Internal referencing based on the Jones-Matrix-Eigenanalysis method enables accuracy of 0.01 dB for PDL and repeatability below 10 fsec for PMD measurements.
An eight-channel polarization controller that uses eight Phoenix PSC all-fiber polarization controllers offers both manual polarization control and analog voltage control in a 19-inch rack configuration. Each controller within the unit consists of three variable waveplates controlled by thermal variation of fiber birefringence. Manual control of the state of polarization can be achieved in all eight fibers simultaneously. Applications include polarization control from optical source arrays, polarization characterization of components, and PMD emulation.

The One-Touch installation system reduces installation time with preinstalled pigtails in the slide-out “Valet Parking” design. The FSC supports patch and splice applications with an all-in-one 12-fiber cassette. Fiber-optic termini conform to GR-326 standards and the FSC has been third-party tested to GR-487 specifications. The cabinet is well suited to high traffic areas where critical failure may occur, rural FTTH deployments with a limited number of users, and as a replacement for larger cabinets where network design calls for fiber being deployed deeper in the network.
The FPU-Polyimide Unit is a handheld fiber preparation device that removes polyimide, metallic, and carbon-coated optical fibers using Ion Enhanced Cold Plasma (IECP) stripping. This technology ionizes the atmosphere surrounding the plasma field, creating a steady electric arc immune to altitude, humidity, and temperature, thereby eliminating harsh chemicals, mechanical blades, and dependency on environmental conditions during the stripping process. Guided fiber holders place the fibers in the correct strip length position for fusion splicing and connectorization. The built-in microprocessor controls all critical stripping, cleaning, and cleaving processes. The device was created for standalone use, but is compatible with several common fusion splicers.
