The JDSU SN Series fiberoptic switch is GR-1221 qualified and designed for use
in central office network applications. This reliable, miniature optical component
is available as a 1x1 (on/off), 1x2, and 2x2 switch.
Collimated lenses and a moving mirror minimize insertion loss and improve the
repeatability and stability of the switch parameters. The switch itself is directly
mounted on printed circuit boards (PCBs), and is equipped with status contacts
to provide an electrical readout of the switch position. Latching operation ensures
that the switch remains in position following power loss.
On request, JDSU also provides customized modular assemblies that incorporate
taps, wavelength division multiplexers (WDMs), splitters, and other components.

1. Insertion loss is specified for the 1290 to 1330 nm and 1520 to 1570 nm wavelength ranges, all polarization states, and does not include connectors. Add 0.3 dB maximum
over operating temperature range. Add 0.1 dB maximum for extended wavelength operation up to 1610 nm.
2. Excluding connectors.
3. A 5 V DC 40 mA pulse of 20 ms duration is recommended.
4. The switch can be operated over the short term from -5 to 70 °C for 96 consecutive hours or less and a total of 15 days or less over a one year period.

中风发生时，一切都是以秒来计算的。延误治疗可能导致大脑重大损伤。伦敦大学医学院的一位博士Alistair McEwan已经获得行为医学研究所(Action Medical Research)的同意，为急救人员开发一种无线诊断系统来减少时间延误。感谢抗血栓药物，一些病人在病情发作的三个小时之内可以完全恢复。但出血也会导致中风。医生在治疗之前需要确定发病原因，因为不适当的服用抗血栓药物会加重损害。...[详细]
