The Optical Fiber Network Saddles are designed with rounded edges to provide a smooth surface between the mount and cable, helping prevent potential stress on the cable and damage to its insulation through snagging or abrasion. The saddles are available in single- and dual-capacity versions, allowing users to select the appropriate capacity for specific fiber-optic-cable routing applications. The saddles are also available in push-mount or adhesive-mount versions, providing further flexibility of application. Each single-capacity saddle can accommodate a maximum bundle size of 1.06 inches in diameter, while the double-capacity version may be used for routing two bundles of the same size. The saddles are constructed of a durable nylon material and are available in natural and black colors.

The HTS-11 High Tensile Strength Stripper is designed to remove outer coatings from 250-micron and 400-micron UV resin-coated fibers to ensure high-strength splicing. A pair of blades removes the coating around the fiber after the fiber is heated. Because the blades do not touch the actual surface of the fiber, the strength does not degrade, according to the company. A temperature change-over switch has four settings, allowing the intensity of the heat to be increased. The stripper operates from a 100 V-240 Vac power source through an AC adapter and is used in conjunction with the FSM-30SF and FSM-30PF high-strength factory splicers.

The MP1570A is a portable analyzer that supports DS-1 to OC-192c in a single mainframe. It can be used during R&D and manufacturing to analyze optical circuits as well as during the installation and maintenance of fiber networks. The analyzer has the ability to measure SONET, SDH, PDH, ATM, and signal bit rates from 1.5 Mbits/sec to 10 Gbits/sec. The MP1570A was designed with a number of built-in functions, including concatenation mapping from OC-3c to OC-192c, CID pattern, and tandem-connection monitoring. There are also separate plug-in units so the analyzer can be configured to meet specific test requirements.
Developed specifically for integration in high-speed DWDM transmission systems, the IPD-10 is an integrated photo detector that enables real-time monitoring of the optical power through each channel with minimal insertion loss, according to the company. Properties include a broad wavelength range covering both C- and L- bands, low backreflection, and high photocurrent. A built-in tap coupler enables power monitoring with a minimal loss of <1 dB, which is uniform over the entire wavelength range. The detector also contains up to 10 channels and provides for simultaneous monitoring of each channel.
The FTB-5500 PMD analyzer's measurement range covers 0.05 psec to 200 psec and uses the field-oriented interferometric technology to characterize the PMD of any optical link over a 50-dB dynamic range, so that no communication is required between the handheld polarized light source and the lightweight platform. The software features one-button testing capabilities with the auto-range function, the ability to characterize any optical fiber with high coupling or weak-mode coupling, multiple-measurement and auto-naming file storage functions, and a statistical table in order to perform multiple-trace analysis.

The ACT2 tests two multimode fibers at once for loss at two wavelengths, calculates cable length, stores data for later readout on a PC, and includes a talkset for communications between test crews. The tester works by testing one fiber at 850 nm while another fiber is being tested at 1,300 nm. The two fibers are then switched at the meter and retested. The meter analyzes the loss data, calculates the length of the cable, and stores data from the tests. The data is stored in a database organized by cables and fibers, which has memory for complete test data up to 250 cables and 500 fibers.
