What is BS EN 61300-2-48 – Fibre optic interconnecting devices about?
BS EN 61300-2-48 details a procedure for determining the suitability of a fibre optic device or closure to withstand variations in humidity and temperature that may occur during operation, storage and/or transport.
The test provided in BS EN 61300-2-48 is intended to indicate the performance of such devices when exposed to heat and humidity followed by short-term freezing.
In general terms, BS EN 61300-2-48 provides a high temperature to induce potential failures due to softening and expansion, a high humidity to encourage moisture absorption and swelling and a low temperature to facilitate ice formation, embrittlement and contraction.
BS EN 61300-2-48 differs from other cyclic environmental tests, notably the damp heat cyclic test of IEC 61300-2-46 and the composite temperature-humidity cyclic test of 61300-2-21, by incorporating alternative levels of severity.
This is achieved through:
- A greater number of cycles
- A greater cyclic temperature range
- A decreased cyclic period
Who is BS EN 61300-2-48 - Fibre optic interconnecting devices for?
BS EN 61300-2-48 on fibre optic interconnecting devices is useful for:
- Electrical engineer
- Manufacturer of fibre optical wire
- Telecommunication companies
- Maintenance and repair agencies
- Fibre optic interconnecting device manufacturers
Why should you use BS EN 61300-2-48 - Fibre optic interconnecting devices?
Fibre optic cables run thousands of miles with multiple interconnecting devices. These devices face quite some variation in temperature and humidity.
BS EN 61300-2-48 provides guidelines to test these devices for their resistance against change in humidity and temperature.
Use BS EN 61300-2-48 best practice guidelines can reduce chances of failure due to repetitive change in temperature and humidity. BS EN 61300-2-48 can help you in selecting fibre optic interconnecting devices with required characteristics.
What’s changed since the last update?
BS EN 61300-2-48:2009 supersedes EN 61300-2-48:2003.
The main changes are the addition of the Category O cycle procedure and the severity reconsideration.
