Standard Optical Interleaver
An innovative technique for expanding the number of channels per fiber involves an optical device, called an optical interleaver. For example, in most DWDM equipment, the standard channel spacing is 100 GHz. But spacing the signal-carrying frequencies every 50 or even 25 GHz can double or even quadruple the number of channels per fiber. This job is accomplished by an optical interleaver. Such a device takes two multiplexed signals with 100-GHz spacing and interleaves them, creating a DWDM signal with channels spaced 50 GHz apart. The process can be repeated, creating even denser composite signals with 25-GHz or 12.5-GHz spacing. The signals at the receiving end are recovered with the same devices used as splitters or optical de-interleavers. Thus, devices and/or networks can be upgraded without requiring that all devices be upgraded, or network bandwidth can be increased.

PPS Clamp Transformer
PPS2 provides power supply to the PD detectors installed on HV cable when low voltage AC power is not available. The PPS2 takes the required power directly from the High Voltage power line under monitoring by means of units clamped on the HV power cable(s).PPS2 is designed to withstand High Voltage line failure events such as temporary overload and short circuit conditions. An internal detection and self limiting circuitry guarantees that PPS2 and the connected equipment survives in case of such events.

High Frequency Transformers
Osborne High Frequency Current Transformers operate at frequencies higher than 50/60 Hertz. Their purpose is to reduce high frequency system currents to lower values that are appropriate for instrumentation and/or protection circuits. They have been designed to meet specified current ratios, and burden impedance at a specified transformation error. One area of unique Osborne expertise is in designing for phase shift when high frequency current transformers are to be used for power measuring applications.
