AMT8300T4 6F/ L and AMT8400T 4 6F/L re ceivers op erate from a 3-V supply and provide high-speed data handling for 800- and 1,300-nm fiber applications. The devices, which detect fiber-optic signals and convert them into electrical signals, enable small-form-factor transceivers for high-speed 2x Fibre Channel and emerging 2.5-Gbit/sec Infiniband fiber-optic networks. The AMT8300 offers minimum sensitivity of -20 dB and optical overload of better than 0 dB for 850-nm applications, and the AMT8400 features minimum sensitivity of -23 dBm and optical overload of better than 0 dBm for 1,300-nm applications.
The RSU family of fusion splicers' optimized processes and automated functions result in faster and more accurate operations. With automatic fusion current control, the RSU controls the current by processing the hot image in real time to be able to hold a constant temperature throughout the splicing process, which improves results when splicing sensitive fibers or fiber combinations with different mode-field diameters. Using overlap and pull values, the splicer calculates and uses additional overlap by measuring the differences between fiber gaps. A tunable estimation program optimized for each splice method improves the RSU's performance, making estimating more accurate.
The LC loopback assemblies are based on the LC interfaces that are used to test the transmission capability and re ceiver sensitivity of network equipment, providing a straightforward "go/no-go" test result. The loopback features a compact housing that is easy to handle and does not have the external loop of fiber-optic cable typical of other loopback connectors. The loopbacks are available in singlemode, 50/125 multimode, and 62.5/125 multimode versions.

The 16-, 20-, and 32-channel DWDMs encompass the C-band and L-band of the 200-GHz ITU grid. The high-port-density DWDMs complement the company's existing line of 4-, 8-, and 10-channel DWDMs. The narrow bandpass thin-film-filter devices are part of a family of growing high-performance devices that allow individual wavelengths to be combined onto and separated from a single optical fiber. The 32-channel DWDM product line incorporates thin-film-filter-band separators. A C/L-band separator combines or separates the C-band from the L-band. The main application of the band separators is to more efficiently use the 200-GHz ITU grid by opening up the L-band to additional channels. The DWDM products are available in either a low-profile cassette for card applications or a module compatible with AMP ATDU or Lucent LGX distribution hardware.

The GT10-1310TR is a self-contained, single-power-supply data transceiver that provides customers with an efficient alternative to current solutions. It is optimized for OC-192/STM-64 applications. A direct modulated 1,310-nm laser module and PIN detector-based optical-receiver module convert data streams between the electrical and optical domains. A high-performance laser driver and receiver amplifier are also incorporated to provide optimum signal levels throughout the assembly. A 16:1 multiplexer and a 1:16 demultiplexer translate between OC-192/STM-64 data rates and OC-12/STM-4 rates. The unit is compact and space efficient, measuring 5x4x0.7 inches with an integrated heat-sink. All sensitive active components are hermetically sealed. The transceiver module runs on a single 5-V power supply, with all signal interfaces via twin 80-pin surface-mount connectors. Optical signals are accessed via fiber pigtails with customer-specified connectors.

The SwitchingFilter SF100 and SF200 products are optical add/drop multiplexer systems designed for applications where dynamic channel multiplexing and demultiplexing are required. The systems are both available on the ITU grid at channel spacing of 100 GHz and 200 GHz, in channel configurations of four to 40. The SF100 incorporates the company's MultiFiber and FiberFilter components for demultiplexing and multiplexing in 100-GHz channel spacings that enable the dynamic switching of wavelengths based on the user's individual requirements. The products feature a patented fused fiber Bragg grating technology that delivers flat passband and low insertion loss, while maximizing temperature ranges from -40°C to +85°C.

This family of singlemode and multimode fiber-optic adapter products provide twice the density of SC fiber adapters, accommodating 24 duplex fiber connectors in the same amount of space occupied by 12 SC fiber ports. The family consists of an individual adapter, an adapter in a keystone package, and a six-pack modular panel. The keystone package adapters fit into modular network patch panels and faceplates. With a typical insertion loss of <0.3 dB, these adapters are ideal for use in demanding fiber-optic networks and fiber-to-the-desk applications.

The FiberStrip 7030 machine was designed for stripping buffers and/or coatings from glass fibers with the highest possible quality and repeatability. Light and portable, the FiberStrip 7030 is well suited for field use, although it is equally well suited for high production use in a factory environment and serves as a companion to fiber cleavers and fusion splicers. It overcomes the variability in strip quality that is typical of manual stripping methods, with features such as the precision die blade and centering system, adjustable temperature heating, dwell-time system, and the rate-controlled stripping system. Special grippers are available for use with jacketed cables and an adapter is available to accept more popular fusion splicer fiber holders on the market.

The TRA-BOND F123LV is a rigid two-part epoxy system for numerous fiber-optic applications. The low-viscosity, fast-curing material has been used for bonding fiber-optic bundles, potting glass fibers, and terminating single and multimode connectors. At a cure temperature of 100°C, the epoxy system will cure in 5 min, while at 150°C, the cure time is 1 min. The three-step color change ensures that the material is completely mixed and cured. High strength and impact resistance bonds can be formed to material such as glass, ceramics, metals, and many plastics. If the viscosity of the material is not suitable to your needs, the company also offers other viscosity variations of the material to match your requirements.
The Model D510 T1 test set is a handheld, easy-to-use field-rugged test set intended for the installation and maintenance technician to analyze and correct common problems arising in T1 networks.

The FTB-5500 PMD analyzer is a critical testing tool for telecom-related companies working with high data rates. PMD limits transmission quality, often referred to as the bit-error rate. With the deployment of a 10-Gbit/sec system and 40-Gbit/sec data rates, characterizing PMD becomes a necessity over installed or even new fiber. The FTB-5500 PMD analyzer measurement range covers 0.05 psec to 200 psec. The module uses field-oriented interferometric technology to rapidly and accurately characterize the PMD of any optical link over a 50-dB dynamic range. No communication is required between the handheld polarized light source and the lightweight platform. The software is easy to use and beginners can use the one-button testing capabilities with the auto-range function to determine the most suitable scanning range for accurate measurement. The multiple measurement and auto-naming file storage units mean the user can characterize the fiber over different periods of time without manipulation.
