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 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.
Each LDM-4604DFB module has four butterfly mounting sockets that are hardwired to a standard DFB laser-pin configuration. Up to four modules and 16 lasers can be mounted in one LDM-4616 chassis. Each socket provides electrical connectors for laser drive current, photodiode feedback, TE cooler current, thermistor sensor signals, and case ground. The modules can be mixed with pin-configurable mount modules for mounting pump lasers in the same chassis. This modular approach gives greater flexibility to mix package types or leave space in the mount chassis tray for other components. Rackmount slide rollers allow easy access to the entire mounting tray, simplifying module replacement as well as laser configuration and replacement. Other features include fiber-management spools and interchangeable fiber-optic connectors.
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.
