摘要： There is a need to provide a multirate burst mode receiver for an OLT to be capable of receiving a high-speed burst signal without the need for a special capability of an ONU in a PON system including a mix of ONUs at different transmission bit rates. A multirate burst mode receiver according to the invention includes a signal input discrimination section and a bit rate discrimination section. The signal input discrimination section detects an average amplitude to discriminate signal input. The bit rate discrimination section detects an envelope curve for a high-frequency component to discriminate a signal bit rate. Based on a discrimination result from the signal input discrimination section and the bit rate discrimination section, the multirate burst mode receiver switches a setting for an optical signal reception section and a serial-parallel converter corresponding to the reception bit rate.

摘要： Disclosed herein is an electronic apparatus produced using a high-temperature lead-free solder alloy which makes it possible to form soldered joints having no variations in strength and which has an excellent balance between strength and solderability. The lead-free solder alloy is an alloy which is made of an element A and an element B and which has a composition composed of AmBn being a stable phase and the element B in an equilibrium state at room temperature. When the lead-free solder alloy is solidified by quenching, the element A is dissolved in a room-temperature stable phase of the element B so that a supersaturated solid solution is formed, and when melted for soldering and then solidified, the alloy returns to its equilibrium state and has a composition composed of the stable phase AmBn and the element B and therefore maintains strength due to the presence of the stable phase AmBn even when reheated to a soldering temperature.
摘要翻译：本文公开了使用高温无铅焊料合金制造的电子设备，其使得可以形成没有强度变化的焊接接头，并且在强度和可焊性之间具有优异的平衡。无铅焊料合金是由元素A和元素B制成的合金，其组成由AmBn构成稳定相，元素B在室温下处于平衡状态。当无铅焊料合金通过淬火固化时，元件A溶解在元件B的室温稳定相中，从而形成过饱和固溶体，当熔化熔化然后固化时，合金回到其平衡状态并且具有由稳定相AmBn和元素B组成的组成，因此即使在再加热到焊接温度时也由于存在稳定相AmBn而保持强度。
