As the speed of optical networks grow and as switching functions are increasingly pushed into the optical layer, demands for Dynamic Signal Control (DSC) technology become enormous. We have determined that DSC mainly includes the following technologies:
Dynamic polarization control
Dynamic power control
Dynamic timing and phase control
Dynamic dispersion control
DSC technology plays a critical role in the deployment of next-generation optical networks because of its capability of restoring the integrity of optical signals when they travel at high bit rates (over 10 Gb/s) and/or for long distances (over 300 kilometers). DSC based products can also dynamically conduct gain flattening, add/drop wavelengths and control the timing of optical transmission in order to enable all-optical networks. As of today, very few products in the DSC category are available to fulfill the needs of network growth. General Photonics is positioned to be a leader in DSC technology by providing an array of key dynamic signal control products.

The OBR 4400 takes the industry's first ultra-high resolution OTDR with backscatter-level sensitivity designed for component- and module-level reflectometry to the next level. With a small, easily transportable platform, the capability to "see" reflections out to 2 kilometers with no dead zone, and integrated temperature and strain sensing, the OBR 4400 gives you the ultimate in fiber diagnostics. The OBR 4400 uses swept-wavelength coherent interferometry to measure minute reflections (< 0.0003 parts per billion) in an optical system as a function of length with spatial resolution less than 50 microns. This provides the user with precision reflectometry and unprecedented optical-module inspection and diagnostic capabilities by providing the ability to locate and troubleshoot splices, connectors, fiber bends and breaks, insertion loss points, track polarization, verify PM components and more.

Now in its fourth generation, the Loom Laser series Thread-Break Detection system uses cutting-edge laser and microprocessor technology to provide protection from thread breaks in any weaving environment.
Thread breaks are detected when the CPU senses small changes in the light received by the photocell (receiver). The system is programmed to differentiate between actual thread breaks and false signals generated, for example, when a dust particle or an insect passes through the beam.
Lasers can be strategically placed at critical points-the whiproll, back shed, front shed, or on the lay-to give complete thread-break coverage.
The advanced capabilities of the LL-2000 Loom Laser can detect threads as small as 30 microns on looms operating between 120 and 600 rpm. At the same time, the system is immune to changes in ambient light, and can withstand vibrations up to 14mm in amplitude at the surface of the receiver sensor.

Up to 24 channels of Return Loss Measurement. The high resolution reflectometer measures Return Loss from 10dB to 72dB.
The OP930 supports a CW source mode. For the Return Loss measurement the laser sources are pulsed in the nanosecond region. For certain measurements a continuous modulated (CW) light signal is a required.

Insertion loss (IL) and return loss (RL) on fiber optical components are measured fast and accurately with the OP930. The return loss is measured with the "no mandrel" method, meaning neither matching gel nor mandrel wraps are required at the far end of the cable. The insertion loss is measured by utilizing the stable transmitter of the return-loss as the source in combination with the precision optical power meter.
