What is BS EN IEC 61300‑3‑21 - Spatial switch about?
BS EN IEC 61300 is a series on fibre optic interconnecting devices and passive components. The broad variety of passive optical components applications include multichannel transmission, distribution, optical taps for monitoring, pump combiners for fibre amplifiers, bit-rate limiters, optical connects, route diversity, polarization diversity, interferometers, and coherent communication. BS EN IEC 61300‑3‑21 describes a method to measure the switching time and related performance parameters of a fibre optic spatial switch when the actuation energy is applied or removed to change the state of the switch.
Who is BS EN IEC 61300‑3‑21 - Spatial switch for?
BS EN IEC 61300‑3‑21 on fibre optic interconnecting devices and passive components is useful for:
- Telecommunication equipment manufacturers
- Fibre optic component manufacturers
- Design engineers
- Quality control personnel
- Research and development facilities
Why should you use BS EN IEC 61300‑3‑21 - Spatial switch?
Passive optical components are data format transparent, combining and dividing optical power in some predetermined ratio (coupling ratio) regardless of the information content of the signals. BS EN IEC 61300‑3‑21 describes a test for the spatial switch to measure their performance parameters. For each optical path through the switch that is to be tested, a stable optical signal from an optical source is applied to the input port(s), and the time-dependent optical signal level at the output port(s) is measured with respect to the time when the actuation energy specified in the relevant specification is applied or removed.
The time taken by a switch to go from an ON state to an OFF state or from an OFF state to an ON state is called switching speed or switching time. For switches configured with fibre optic connector plugs or receptacles (configurations B or C), the appropriate fibre optic patch cords or adaptors are used in the place of the temporary joints. When multiple output ports are measured, each may be connected to a detector, and it should be assured that impairment from reflections is avoided. Using BS EN IEC 61300‑3‑21 you can understand the method to measure the switching time and related performance parameters of a fibre optic spatial switch.
