What is BS EN 61300-2-21- Fibre optic interconnecting devices and passive components about?
BS EN 61300-2-21 is a part of an international multi-series standard that focuses on fibre organisers and closures to be used in optical fibre communication systems.
BS EN 61300-2-21 specifies the methodology to determine the resistance of a fibre optic device to the deteriorative effects of elevated temperature, humidity, and frigid conditions.
BS EN 61300-2-21 is intended to reveal defects in a device under test (DUT) caused by breathing as opposed to absorption of moisture.
BS EN 61300-2-21 describes a test that covers the effect of the freezing of trapped water in cracks and fissures as well as condensation. However, the degree of condensation varies depending on the size and thermal mass of the DUT.
Who is BS EN 61300-2-21- Fibre optic interconnecting devices and passive components for?
BS EN 61300-2-21 on fibre optic interconnecting devices and passive components is relevant to:
- Manufacturers of fibre optic devices
- Manufacturers of optical fibre
- Manufacturers of test chambers
- Manufacturers of test apparatus
- Fibre optic technicians
- Fibre optic installers
- Composite temperature/humidity cyclic testing authorities
Why should you use BS EN 61300-2-21- Fibre optic interconnecting devices and passive components?
Due to the rapid growth in data and information, fibre optic interconnections are proved to be very useful for clock distribution and communication between different parts of electronic computers. There have been raised demands for wider bandwidth in communication systems and higher performance in IT/NW equipment.
BS EN 61300-2-21 describes the procedure regarding the composite temperature/humidity cyclic test on fibre optic interconnecting devices and passive components, which is conducted in accordance with international standards. The performance of the devices and components is checked by placing the DUT in a humidity chamber and subjected to 10 temperature-humidity cycles, each of 24 h duration. BS EN 61300-2-21 also provides you with the information for the preparation of the specimen according to the manufacturer’s instructions or as specified in the relevant specification.
BS EN 61300-2-21 presents you with a test, that differs from other cyclic damp heat tests in that it derives its increased severity from:
- A greater number of temperature variations leading to pumping actions each time
- A greater cyclic temperature range
- A higher rate of change in temperature
- The inclusion of several excursions to sub-zero temperature
BS EN 61300-2-21 is particularly important for fibre optic devices made of a variety of different materials.
By applying, BS EN 61300-2-21 you can learn the basic test and measurement procedures for fibre optic interconnecting devices and passive components which can be helpful for your business.
