Abstract: An insulation piercing connector assembly is provided with a sealing cap mountable over the end of a cable and subsequently insertable between clamping jaws of the connector. The assembled sealing cap and end cable are clamped prior to termination by retaining plates for easier handling and more reliable termination. Insulation piercing contacts of the connector pierce through the body of the sealing cap and insulation layer of the cable during termination. The sealing cap arrangement enables the cable to be inserted between the clamping jaws from a side thereof which is particularly useful in confined spaces.

Abstract: Device for measuring variations of the gain of a laser amplifier at a particular wavelength, as a function of a pumping energy, said device comprising a source supplying continuous light radiation having the said wavelength and a power Pe, said radiation traversing the amplifier with a given radius, a means for tapping part of the amplified radiation at the output of the amplifier, a photoreceiver receiving said part and measuring the power Ps thereof throughout the pumping time, a means for forming the quotient of Ps by Pe and supplying a signal G(t) representing the variations of the gain as a function of the pumping time, wherein the device also comprises means for supplying a signal E(t) representing the increase in the pumping energy used during pumping and means for extracting a signal G(E) representing the gain variations as a function of the pumping energy for the given radius from the two signals G(t) and E(t), by elimination of the time t.It also relates to a process which utilizes this device.
